C0267 on Cadillac by model: symptoms, diagnosis and fix
The Teves Mark IV ABS modulator assembly develops internal leaks and electronic failures, disabling ABS and traction control. The modulator is expensive and integrates the hydraulic pump, valves, and electronic controller into one unit. Moisture intrusion into the electrical connector accelerates failure.
Common Symptoms
- ABS light on
- Traction control disabled message
- Brake pedal drops under ABS activation
- ABS motor runs continuously for short periods
How to Fix
The ABS modulator can be sent to a specialty rebuilder for significantly less than dealer replacement cost. Apply dielectric grease to all electrical connectors during reinstallation. Bleed the ABS system using a scan tool to cycle the pump and valves. Inspect the wheel speed sensors and tone rings during the repair.

Frequently asked questions
What does C0267 mean on a Cadillac?
C0267 stands for "ABS Pump Motor Circuit Open." C0267 is a chassis/brake code (predominantly GM) meaning the electronic brake control module commanded the ABS pump motor on but detected no electrical feedback, indicating an open pump motor circuit. The pump rapidly modulates brake pressure during ABS events, so an open circuit prevents it from operating and disables ABS function, though normal base braking remains. It is frequently caused by wiring/connection problems or an internal module fault and should be repaired to restore anti-lock braking. On Cadillac it is documented across 1 model: Eldorado.
What are the most common causes of C0267?
The most common causes of C0267 are: Poor power or ground connection at the EBCM/pump connector, Open or corroded wiring in the pump motor harness, Faulty ABS pump motor, Internal EBCM/ABS module fault, Blown ABS pump fuse or faulty relay, Damaged 2-way motor harness terminals. The specific cause varies by vehicle.
How much does it cost to fix C0267 on a Cadillac?
Published repair estimates on Cadillac range from $400 to $1,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
