EBCM MALFUNCTION





Circuit Description
This DTC identifies a malfunction detected by the MDI custom IC. It also insures that the cause of the malfunction is not a result of a problem with the enable relay under a DTC A055 malfunction.

Diagnosis

Fail Action
The EBCM will not operate properly and ABS is unpredictable. ABS is therefore disabled and the ABS warning lamp is turned on. The brake warning lamp is turned in the rear piston is not at the top of the bore, since this could cause degradation of the base brakes.
