Circuit Diagram:

LEFT FRONT MOTOR CIRCUIT OPEN
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 56 sets if:
^ LF motor circuit is open.
^ This code will 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.

Motor resistance is less than 2 ohms.
