ANTI-LOCK BRAKE SYSTEM - TC and CG Terminal Circuit


DESCRIPTION

DTC output mode is set by connecting terminals TC and CG of the DLC3.
The DTCs are output by the blinking of the ABS warning light.

HINT:
When each warning light stays blinking, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in each ECU is suspected.

INSPECTION PROCEDURE

NOTICE:
After replacing the master cylinder solenoid, perform zero point calibration (Click here).
