DESCRIPTION
Connecting terminals TC and CG of the DLC3 causes the AWD control ECU to display 2-digit DTCs by flashing the AWD warning light.
HINT:
When each warning light remains blinking, a short to ground in the wiring of terminal TC of the DLC3 or an internal short to ground in each ECU is suspected.

Cruise Main Indicator Light Circuit
DESCRIPTION
The ECM detects a cruise control main switch signal and sends it to
the combination meter assembly through CAN. Then the CRUISE main indicator
light comes on.
The CRUISE main indicator light circuit uses CAN for communication.
