DTC 57





CIRCUIT DIAGRAM





INSPECTION PROCEDURE

CIRCUIT DESCRIPTION:
These DTCs identify a motor circuit that is shorted to ground. This malfunction will not allow the motor to be controlled at the commanded current rate or will cause the driver circuit to allow current directly to ground.

FAILURE CONDITION:
DTCs 57, 62 and 65 can be set anytime. If the Electronic Brake Control Module (EBCM) detects an out of range voltage on either of the motor circuits (indicating a circuit shorted to ground), a malfunction exists.
