Circuit Diagram:







LEFT FRONT MOTOR CIRCUIT GROUNDED
The ABS control module detects a fault in any of the motor circuits by monitoring a bias voltage. If a motor circuit is open, grounded, or shorted to battery, ABS will be disabled and the antilock and brake telltale will be turned On.

CODE PARAMETERS

Code 58 sets if:
^ LF motor circuit is grounded.
^ This code can set at all times except when a previous failure has disabled ABS operation.

DIAGNOSTIC AIDS
When attempting to diagnose an intermittent problem, use the Scan tool[1] to review supplemental diagnostic information. The supplemental data can be used to duplicate a problem.


Check the tightness of the female terminal grip with a spare male terminal.

[1] Select Malfunction History from Scan tool ABS menu.
