DTC 42

CIRCUIT DIAGRAM





INSPECTION PROCEDURE

CIRCUIT DESCRIPTION:
This DTC is designed to detect a slipping rear ESB. During initialization and braking, the rear motor is rehomed. If the ESB slips, the motor/piston will move. During the next ignition "ON" initialization, a rehome of the motor verifies that the motor/piston remained at the home position. If motor movement is detected, the ESB must be slipping.

FAILURE CONDITION:
DTC 42 can be set during initialization. If the Electronic Brake Control Module (EBCM) detects that the ESB could not hold the piston in the home position, a malfunction exists. DTC 86 is always set with DTC 42.
