VEHICLE STABILITY CONTROL SYSTEM - TC and CG Terminal Circuit |
DESCRIPTION
Connecting terminals TC and CG of the DLC3 causes the ECU to output the DTCs by blinking the ABS warning light and VSC OFF indicator light.
WIRING DIAGRAM
- HINT:
- When the warning light and indicator light continue to blink, there may be a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in one or more ECUs.
INSPECTION PROCEDURE
- NOTICE:
- After replacing the brake actuator assembly, perform calibration (HILUX_TGN26 RM000000XHR073X.html).
- Before disconnecting the connector, make sure that there are no problems with the connection.
- After disconnecting the connector, make sure that the connector case and terminals are not deformed or corroded.
1.CHECK CAN COMMUNICATION SYSTEM |
