C0014

DTC C0014 Solenoid Relay Contacts or Coil Circuit Open






Circuit Description
The solenoid relay is internal part of the EBCM.
Battery voltage is supplied from terminals A and B for the relay switch at all times. When the ignition switch is turned ON, battery voltage from terminal All 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 motor with battery voltage. The relay will remain in the on position as long as the ignition switch remains on, or a DTC 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 8.0 volts for 1/4 of a second.

Action Taken When the DTC Sets
The solenoid relay is commanded off, removing battery voltage from the 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 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 history data.

Diagnostic Aids
Typical Causes of DTC C0014.
1. Weak or discharged battery.
2. Loose or corroded battery terminal.
3. Engine block ground from battery poor.
4. Poor or loose ABS fuse contacts.
5. Poor EBCM terminals A, B, A11.
6. Low voltage to EBCM terminals A and/or B.
