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.
