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.
