Code C1217 Cadillac Description

The system relay is energized when the ignition is ON. The system relay supplies voltage to the solenoid valves and the pump motor. This voltage is referred to as the system voltage. The Electronic Brake Control Module (EBCM) controls each solenoid valve by grounding the solenoid. The EBCM controls the pump motor by grounding the control circuit. The pump serves 2 purposes:
- Transfers brake fluid from the brake calipers to the master cylinder reservoir during pressure decrease events.
- Transfers brake fluid from the master cylinder reservoir to the brake calipers during pressure increase events.

Frequently Asked Questions about C1217 Cadillac Code

1. What does the OBDII code C1217 mean on a Cadillac?

C1217 indicates an issue with the BPMV (Brake Pressure Modulator Valve) pump motor relay contacts, specifically an open circuit.

2. What are the common symptoms of the C1217 code on a Cadillac?

Common symptoms include the ABS warning light being illuminated, reduced or disabled ABS functionality, and possible brake performance issues.

3. What causes the C1217 code to appear on a Cadillac?

The code can be caused by a faulty pump motor relay, damaged wiring or connectors, a malfunctioning BPMV, or electrical issues such as blown fuses.

4. Can I still drive my Cadillac with the C1217 code active?

While the vehicle may still be drivable, the ABS system may not function properly, which could compromise safety during hard braking or slippery conditions.

5. How do I diagnose the C1217 code on my Cadillac?

Start by inspecting the wiring and connectors at the BPMV and pump motor relay for damage or corrosion. Use a multimeter to test for continuity and check the relayâ€™s functionality.

6. Can a blown fuse cause the C1217 code on a Cadillac?

Yes, a blown fuse in the ABS or BPMV circuit can interrupt power to the pump motor relay, triggering the code.

7. How do I fix the C1217 code on a Cadillac?

Repairs may include replacing a faulty pump motor relay, repairing damaged wiring or connectors, or replacing the BPMV if it is defective.

8. Is the BPMV the same as the ABS module in a Cadillac?

The BPMV is part of the ABS system and controls brake pressure during ABS activation, but it is a separate component from the ABS control module.

9. How much does it cost to repair the C1217 code on a Cadillac?

Repair costs vary depending on the issue, ranging from $100 for a relay replacement to over $1,000 if the BPMV needs to be replaced.

10. Can a low battery or voltage issue trigger the C1217 code on a Cadillac?

Yes, insufficient voltage can affect the pump motor relayâ€™s operation, potentially causing the code to appear. Ensure the battery and charging system are in good condition.
