CHECK HARNESS AND CONNECTOR (TERMINAL TC of DLC3 - BODY GROUND)
CRUISE CONTROL SYSTEM - TC and CG Terminal Circuit |
DESCRIPTION
Connecting terminals TC and CG of the DLC3 causes the system to enter self-diagnostic mode. If a malfunction is present, the MIL will blink.- HINT:
- When a particular warning light remains blinking, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in the relevant ECU is suspected.
