New Seminars Cover the Latest Technology
New cars and trucks are being packed with more technology faster than ever before. The Gear Absolute Position sensor, Selective Catalyst Reduction, StrategyBased Diagnostics, GM Multiple Diagnostic Interface, Passenger Presence System, active head restraints and shape memory alloys — they are just a few of the new components and systems now being used on modern vehicles. To help technicians keep up with the latest technology, ACDelco has developed several new ACDelco seminars that are available now through your local ACDelco distributors.
2014 Vehicle Technology Update (S-EL06-44.01SEM) The 2014 Vehicle Technology Update seminar covers the latest advancements in powertrain, drivetrain, and electrical technology, including: • New GM Gen V engines • Stop/start systems • Manual and automatic transmission innovations • Electric vehicles • New electronic differentials • Electric power steering • New circuit protection • Hazard avoidance systems The seminar reviews the new TR6070 7-speed manual transmission in the 2014 Corvette. The transmission features Active Rev Matching, which uses
a GM-patented Gear Absolute Position (GAP) sensor mounted to the top of the transmission housing that provides a signal of the real-time position of the shifter from the transmission to the ECM. With this information, the engine RPM is controlled to better match the next gear selection for smoother upshifts and downshifts. To activate Active Rev Matching, the driver presses either paddle on the steering wheel. The new TL80SN 8-speed automatic transmission in the 2014 CTS sedan also is highlighted. The transmission has 10 possible gear ratios – eight forward and two reverse (if the reverse inhibit function is active) through the gear sets. Below 7 mph, the transmission shifts into Reverse, but at a different gear ratio. When below 7 mph, the C4 clutch is applied instead of the continued on page 2

New Seminars Cover the Latest Technology – continued from page 1 C3 clutch. This changes the gear ratio for Reverse and acts as a cushion to ease the shift into Reverse. This gear ratio change works only if the vehicle is in Drive or moving in a forward direction, and then shifted into Reverse. If a normal shift from Park to Reverse is performed, then the normal C3 clutch is applied and the full Reverse gear ratio is used. The haptic feedback of GM’s active safety seat in several new Cadillac models also is covered in the seminar. A vibration in the driver’s seat bottom cushion alerts the driver of a number of concerns. Two motors providing the vibration are located on the left and right sides in the seat cushion. The modules that can request haptic motor operation are the front and rear parking assist control module, vehicle camera module and side object sensor modules.
Diesel Technology Insights (S-EP08-36.01SEM) The Diesel Technology Insights seminar covers the common fuel rail s ystem and emission reduction systems. In addition, it includes several case studies reviewing diesel engine conditions found in a VW Jetta, Chevrolet Silverado, GMC Savana, and Ford F-250. In the seminar, various diesel engine components are reviewed, such as high-pressure fuel pumps that generate 26,000 psi or more of fuel pressure and piezo fuel injectors that operate up to five times faster than conventional solenoid valves. These are just two components that enable the engine to run more efficiently, which helps reduce emissions. Other emission reduction systems typically found on today’s diesel engines include Exhaust Gas Recirculation (EGR), the Diesel Oxidation Catalyst (DOC), the Diesel Particulate Filter (DPF), and Selective Catalyst Reduction (SCR). The SCR catalyst reduces NOx emissions by injecting Diesel Exhaust Fluid (DEF), or urea, into the exhaust gases prior to entering the SCR. The exhaust heat converts DEF into ammonia that reacts with the SCR to form nitrogen, carbon dioxide and water vapor. The case studies take a look at some typical repairs. On the Jetta with
the 2.0L TDI engine, the oil pressure warning lamp is on but the oil level is OK. The testing procedure covers checking the oil pressure and switch. The Silverado with the 6.6L Duramax engine is low on power, is displaying an Engine Power is Reduced message, and previously displayed a Clean Exhaust Filter message. The case study covers the service regeneration process for the DPF along with several related DTCs.
SRS and Safety Systems (S-ST10-01.01SEM) The SRS and Safety Systems eminar covers the latest Supplemental s Restraint Systems (SRS), including the subsystems and components, along with safety and diagnostic procedures. Topics include: • SRS overview • Sensor testing and tools • Passenger Presence System • Performing repairs • Calibrating the system • New safety technologies New vehicles can have up to 10 airbags. The Sensing and Diagnostic Module (SDM) can deploy the individual airbag modules depending on several conditions based on inputs from rollover sensors, side impact sensors, door pressure sensors, front crash sensors and rear impact sensors. The seminar reviews the operation and testing of these sensors. The Passenger Presence System, which communicates the occupancy status of the front passenger seat to the SDM, also is highlighted in the seminar. Examples of several systems from various manufacturers are covered. In addition, new technologies are reviewed, including the Pedestrian Impact Detection system, motorized seat belt retractors, inboard side airbags, and active head restraints. The case studies in the seminar take a look at different reasons for the SRS warning lamp being illuminated. One study features a Ford Escape with an illuminated SRS lamp and several DTCs and reviews checking the circuits of the Restraints Control Module. Another study covers a Chevrolet Avalanche continued on page 3

The All-New Corvette Stingray The all-new 2014 Chevrolet Corvette Stingray (C7) coupe and convertible offer a driving experience without compromise in performance, technology or design. The Stingray — a name that harkens back to the original 1963 Sting Ray — is all new, with the only carryover parts from the 2013 Corvette being the cabin air filter and the roof rear latch. Most Powerful Standard Model Ever The 2014 Corvette Stingray is the most powerful standard model ever, with the 6.2L V8 engine (RPO LT1) producing 455 horsepower (339 kW) and 460 lb.-ft. of torque (623 Nm). It can accelerate from 0–60 mph in less than four seconds. The all-new small-block V8 engine features a cast aluminum block, cast aluminum cylinder heads with two valves per cylinder and a compression ratio of 11.5:1. Advanced technologies include Direct Injection (DI), Active Fuel Management (AFM), Continuously Variable Valve Timing and an advanced combustion system that delivers more power while using less fuel. The available performance variable-mode active exhaust system further enhances the engine’s output with improved airflow. An exhaust tailpipe flow control valve is installed in each tailpipe in the low restriction exhaust path of the dual outlet muffler, near the exhaust tip. When the tailpipe exhaust valves are open, the low restriction exhaust path is opened to the atmosphere and produces a more powerful exhaust note. The Chassis Control Module uses pulse width modulation to control the actuator that opens the valves. There are four specific exhaust performance modes that result in different behavior of the valves:
Active Rev Matching — activated and deactivated by pressing either of the REV MATCH paddles on the steering wheel — aids in smoother shifting by matching the engine RPM to the next selected gear. On downshifts, engine speed is increased before the clutch is engaged. On upshifts, engine speed is appropriately reduced.
The LT1 V8 is available with a 6-speed automatic transmission or a 7-speed manual transmission.
Checking Engine Oil/Dry Sump Oil Tank
• Weather/Eco Mode: valves closed at all times when the engine is running.
For an accurate reading of the dry sump lubrication system, check the oil level only after the engine has been thoroughly warmed up, after at least five minutes but no more than 15 minutes after engine shutoff.
• Tour Mode: valves closed when the engine is idling and during normal/non-aggressive driving; open during aggressive driving.
The LT1 engine uses a special high-performance oil filter, UPF48R or equivalent. Use of any other filter may lead to filter failure and/or severe engine damage.
• Sport Mode: valves open when the engine is idling and during most driving scenarios.
A noise similar to running water may be heard from the dry sump oil tank when the engine is cold and started. This is a normal sound of oil returning to the tank.
• Track Mode: valves are open at all times. The engine sound enhancement can be turned off in the Vehicle Settings menu. Models with the 6-speed 6L80 automatic transmission or Z51 Performance Package feature a functional vent on the driver’s left side directing air over a heat exchanger for the transmission fluid and a similar arrangement on the passenger side that directs air over a heat exchanger for the Electronic Limited Slip Differential (ELSD) cooler.
Z51 Performance Package The Z51 Performance Package is offered as the top erformance Stingray. With the Z51 Performance Package, p the Stingray is capable of 1.03g in cornering acceleration – comparable to the 2013 Corvette Z06 (1.04). The Z51 package includes: • larger forged aluminum 19-inch front and 20-inch rear wheels • dry sump oil system
The Stingray also is offered with a 7-speed Tremec (TR6070) Manual Transmission with Active Rev Matching.

• Electronic Limited Slip Differential (ELSD) • larger front brakes (13.6-inch vs. 12.6-inch) with black calipers • specific shocks, springs and front stabilizer bars • differential and transmission cooling • a unique Aero Package that reduces lift for high-speed stability • P245/35ZR19 front and P285/30ZR20 rear Michelin Pilot Super Sport ZP summer-only tires Magnetic Selective Ride Control (instantly adjusts shock damping) and Performance Traction Management (five settings of torque reduction and brake intervention) are available.
Brembo Brakes Brembo brakes are standard on the 2014 Corvette Stingray. The brakes feature an aggressive pad material for enhanced braking capability. Brake dust and some slight noise are considered normal. 12.6-inch (320-mm) front rotors and 13.3-inch (338-mm) rear rotors have 35% more swept area than previous-generation brakes. This feature improves stopping distance by 9%. Dual-cast, slotted 13.6-inch (345-mm) front rotors and 13.3-inch (338-mm) slotted rear rotors are included with the Z51 Performance Package. They are cooled front and rear for improved track capability. This feature improves stopping distance by 5%. The Z51 Performance Package uses a twopiece cast front rotor. A slight clicking noise may be heard when the brakes are applied. The 2014 Stingray has four available suspension systems. The front and rear suspension features a short/long arm (SLA) double wishbone design with cast aluminum upper and lower control arms, transverse-mounted composite springs and monotube shock absorbers.
TPM Auto Learn System
Functional exterior elements on all models include a new grille/radiator arrangement, hood vents and front fender cove vents. Venting air out of the hood reduces total front-end lift for improved steering response at high speeds, while the fender vents relieve underhood air pressure to reduce aerodynamic drag.
Aerodynamics is aided by functional venting.
Interior features include configurable
display screens and a head-up display. The lightweight materials, including an aluminum frame; c arbon fiber hood and removable roof panel on coupes; c omposite fenders, doors and rear quarter panels; and carbon-nano composite underbody panels help provide an optimal 50/50 weight balance that supports a world-class power-to-weight ratio.
Configurable display screens and an available head-up display, which vary depending on the driving mode, including the Track display inspired by the C6.R, presents an unprecedented amount of information to the driver. Providing the driver with all the vehicle data shows just how the new Corvette Stingray — from design to materials to engineering — delivers on its high-performance mission.
Coming Fast(er)
The new Tire Pressure Monitor (TPM) Auto Learn system consists of wheel-mounted sensors that transmit RF messages to an in-vehicle receiver and to an Auto Learn Module. These messages are then decoded and placed on the serial data bus by the BCM so they can be displayed on the Driver Information Center. The sensors transmit whether they are located on the LH side or the RH side on the vehicle based on direction of rotation — CW or CCW. The Auto Learn Module detects whether a sensor is located on the front axle or the rear axle, depending on the sensor signal strength. This combination allows the system to assign IDs to the corner locations on the vehicle. The Auto Learn function is repeated at each ignition cycle to confirm that the original sensors are still mounted to the vehicle. If a new sensor has been installed, the system will automatically detect and assign it to the proper corner. The relearn process requires that the vehicle is driven at speeds greater than 25 mph (40 km/h) for about 10 minutes.
Design Many hours were spent in the wind tunnel to enhance the performance and aerodynamics of the Stingray design. 5
2015 Corvette Z06
Even though the 2014 Corvette Stingray is packed with performance, the most capable Corvette ever — the Corvette Z06 — is coming in 2015. It features a new 625 horsepower (466 kW) supercharged 6.2L V8 engine (RPO LT4) and an available all-new high-performance 8-speed 8L90 automatic transmission with full manual control. The track-focused Z07 Performance Package adds a ggressive aerodynamics for greater downforce, Michelin Pilot Super Sport Cup tires, and Brembo carbon ceramic-matrix brake rotors. – Thanks to Art Spong and Sherman Dixon

Extended Cold Crank with Direct Injected Engines 2014-2015 Corvette, Silverado 1500, Suburban, Tahoe, Sierra 1500 and Yukon models equipped with the 4.3L, 5.3L, and 6.2L (RPOs LV3, L83, L86 and LT1) Direct Injection (DI) engines Direct Injection engines may have slightly longer cold crank times, especially during cold ambient air temperatures, than that of port fuel injected engines. Direct Injection systems run at higher pressures and the mechanical pump on the engine must build up the required pressure before the first injection event occurs. Following are typical DI engine crank times using gasoline: Start-up Coolant Temperature

New DOT 3 Brake Fluid A new DOT 3 brake fluid with significant improvements in lubricity, or the capacity for reducing friction, is now available from ACDelco to eliminate a possible squeak noise condition with the brake master cylinder. The squeak noise may be most noticeable when the brake pedal is applied or released. It is most often heard when the brake pedal is slowly applied with the engine on or off. The noise is usually isolated to the master cylinder area. The new DOT 3 brake fluid, ACDelco 10-4090 (GM P/N 19299818) supersedes DOT 3 brake fluid ACDelco 10-4046 (GM P/N 88862806). The improved brake fluid should be used in all GM vehicles that specify DOT 3 brake fluid. To correct the squeak/noise condition, remove the brake fluid from the brake master cylinder reservoir and refill with the new DOT 3 brake fluid. Start the vehicle and fully cycle the brake pedal to allow the fluid to enter the system. The noise condition will diminish while cycling the brake pedal.
