TC and CG Terminal Circuit (from 07/2011)

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: ANTI-LOCK BRAKE SYSTEM (for Hatchback): TC and CG Terminal Circuit
- TC and CG Terminal Circuit

DESCRIPTION

Connecting terminals TC and CG of the DLC3 causes the ECU to display the DTC by blinking the ABS warning light and Slip indicator light.

WIRING DIAGRAM





HINT
When the warning lights continue to blink, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in one or more ECUs is suspected.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM ABS Warning Light Remains ON (from 07/2011)
