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.

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:
  1. After replacing the brake actuator assembly, perform calibration (HILUX_TGN26 RM000000XHR073X.html).
  2. Before disconnecting the connector, make sure that there are no problems with the connection.
  3. After disconnecting the connector, make sure that the connector case and terminals are not deformed or corroded.
1.CHECK CAN COMMUNICATION SYSTEM
  1. Check if a CAN communication system DTC is output (HILUX_TGN26 RM000004PEV00AX.html).
