C0064

DTC C0064 Apply or Release Solenoid Shorted or Open






Circuit Description
Apply and release coils are an integral part of the EBCM. The coils are supplied with battery power when the ignition is in the ON position and the solenoid relay is closed. The EBCM controls the solenoids by grounding the respective coil circuit when necessary.

Conditions for Setting the DTC
When the EBCM senses an open, short to ground or a short to power on any one of the apply or release coils, the respective DTC will set.

Action Taken When the DTC Sets
^ The solenoid relay opens, removing power from the solenoids.
^ The respective DTC is stored.
^ ABS disabled, ABS Warning Lamp turns on.
^ DDRP disabled, Brake Warning Lamp turned on (For C0065 and C0067 only).

Conditions for Clearing the DTC
^ If the conditions that set DTC C0061 through C0068 are no longer present, the DTC may be cleared by using the proper scan tool.
^ The DTC that has not occurred in 100 drive cycles will be cleared from history data.

Diagnostic Aids
Make sure the integrity of the connection between the EBCM and the BPMV is secure, tight and free from corrosion.

Steps 1-7:

Since the solenoid coils are an integral part of the EBCM, any one of the DTC(s) settings will usually indicate an internal fault to the EBCM.
