DESCRIPTION





WIRING DIAGRAM





INSPECTION PROCEDURE

NOTICE:
- If the electric parking brake ECU or electric parking brake actuator is replaced, perform the "RESET MEMORY" and "ACQUIRE TENSION SENSOR ZERO POINT" procedures Programming and Relearning.
- Even after the power switch is turned OFF, the electric parking brake ECU may store a DTC as a result of removing a connector or fuse, as the ECU is still operating. Therefore, during inspection or replacement, turn the power switch OFF and wait for 20 seconds before removing the following: 1) connectors of the electric parking brake ECU, and 2) fuses of the electric parking brake system circuit.
- This DTC may be output if a manual release cable is used. There is no malfunction. Perform the "RESET MEMORY" and "ACQUIRE TENSION SENSOR ZERO POINT" procedures Programming and Relearning.

PROCEDURE
