Master Warning Light Malfunction

DESCRIPTION

The combination meter will turn the master warning light on based on this information.

Warning information is transmitted via the following route: Steering control ECU --> (CAN) --> Skid control ECU --> (CAN) --> Combination meter

Connecting terminals TC and CG of the DLC3 makes the master warning light blink and outputs DTCs.
