Antilock Braking System (ABS)

Motor Circuit Open:

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:
^ L/F 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 (select Malfunction History from Scan tool ABS menu) 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 about 0.5 ohms.
