NO - Go to Power Mode Mismatch in Body Control System Rotate the ignition switch through all positions while observing the ignition switch power mode parameter.ĭoes the ignition switch parameter reading match the ignition switch position for all switch positions? Turn OFF the engine as soon as you have observed the Crank power mode.Īccess the Ignition Switch parameter in the rear integration module (RIM) inputs data display list. Important: The engine may start during the following step. That’s right: the powertrain isn’t even from a normal Corvette, but rather from a Corvette Z06, which is better because a) it’s faster, and b) it has those little inlets in front of its. Turn ON the ignition, with the engine OFF.Īttempt to establish communication with the Powertrain Control Module (PCM) and the Rear Integration Module (RIM).ĭoes the scan tool communicate with the PCM and the RIM? The first is obvious: while the CTS-V looks like your grandfather’s Cadillac, it has the engine and transmission from your crazy uncle’s Corvette Z06. NO - Go to Scan Tool Does Not Communicate with Class 2 Device in Data Link Communications This allows the shift lever to be moved out of the PARK position. When the driver presses the brake pedal the rear integration module receives the brake applied signal and turns off the ground to the automatic transmission shift lock control solenoid control circuit. This causes the solenoid to energize mechanically locking the shift lever in the PARK position. When the rear integration module (RIM) receives a class 2 serial data message from the transmission control module (TCM) or powertrain control module (PCM) indicating that the shift lever is in the PARK position the rear integration module (RIM) grounds the automatic transmission shift lock control solenoid control circuit. The automatic transmission shift lock control solenoid is controlled by the rear integration module. With the ignition ON, battery positive voltage is supplied to the automatic transmission shift lock control solenoid from the ignition 3 relay. The transmission control module (TCM) or powertrain control module (PCM).The automatic transmission shift lock control solenoid. The system consists of the following components. The driver must press the brake pedal before moving the shift lever out of the PARK position. The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running.
