C1214

DTC C1214 Schematic:

CIRCUIT DESCRIPTION
The solenoid valve relay supplies power to the solenoid valves in the BPMV. The solenoid valve relay, located in the EBTCM, is activated whenever the ignition switch is in the ON position and no faults are present. Power is provided to the solenoid valves through the relay from CKT 1242 going into terminal D of the EBTCM. The solenoid valve relay remains engaged until the ignition is turned OFF or a failure is detected.

CONDITIONS FOR SETTING THE DTC
DTC C1214 will set anytime the solenoid valve relay is commanded ON and the solenoid valve relay voltage is less than 8 volts, and ignition voltage is greater than 10.5 volts.

ACTION TAKEN WHEN THE DTC SETS
A malfunction DTC is stored, ABS/TCS is disabled and the ABS and Traction Control indicators are turned ON.

CONDITIONS FOR CLEARING THE DTC
- Condition for DTC is no longer present and scan tool clear DTC function is used.
- Fifty ignition cycles have passed with no DTC(s) detected.

DIAGNOSTIC AIDS
It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction. The Relays are integral to the EBTCM and are not serviceable.
