The solenoid valves are part of the Brake Pressure Modulator Valve (BPMV). The BPMV turns ON and OFF the solenoid valves as deemed necessary to modulate hydraulic pressure to the wheel brakes during an ABS stop.
DTC's C0060 - C0090 can be set anytime the ignition switch is in the ON position.
The Electronic Brake Control Module (EBCM) detects one of the following conditions in the solenoid circuitry:
• | An open |
• | A short to ground |
• | A short to voltage |
• | The ABS is disabled. |
• | The ABS warning indicator turns ON. |
The condition responsible for setting the DTC no longer exists and the Scan Tool Clear DTCs function is used.
Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction.
The following are possible causes of the malfunction:
• | An open, high resistance, or a short to ground in the Battery Positive Voltage circuits |
• | An open or high resistance in the Solenoid Ground circuit |
• | An internal EBCM malfunction |
If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
