C0014

DTC C0014

Circuit Description
The solenoid relay is an internal part of the Electronic Brake Control Module (EBCM).

Battery voltage is supplied from terminals 1 and 2 for the relay switch at all times. When the ignition switch is turned ON, battery voltage from terminal 13 is supplied to the relay coil.

The EBCM will then ground the relay coil circuit to switch the relay ON, this supplies the solenoids and the motor with battery voltage. The relay will remain in the ON position as long as the ignition switch remains ON, or a DTC is set which turns OFF the relay.

Conditions for Setting the DTC
DTC C0014 will set after the ignition switch is ON, and the EBCM commands the relay ON, if the ignition voltage is greater than 10.5 volts and the switched relay voltage drops less than 8 volts for 1/4 of a second.

Action Taken When the DTC Sets
^ The solenoid relay is commanded OFF, removing the battery voltage from all the solenoids and the pump motor.
^ ABS disabled, ABS warning lamp is turned ON.

Conditions for Clearing the DTC
^ If the conditions that set the DTC C0014 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 the history data.

Diagnostic Aids

Steps 1 - 10:

Typical causes of DTC C0014:
^ Weak or discharged battery
^ Loose or corroded battery terminals
^ Engine block ground from battery poor
^ Poor or loose ABS fuse contacts
^ Poor EBCM terminals 1, 2, 13, 21
^ Low voltage to the EBCM terminals 1 and/or 2.
^ Internal EBCM failure
