What Causes C0267? (Most Likely First)
- Fault in the ABS/traction control component this code names (ABS Pump Motor Circuit Open/Shorted) High
- Damaged wiring or a corroded connector in that circuit - road-splash zones corrode connectors High
- Failed related sensor or actuator Moderate
- Control module fault Low
Can I Still Drive with C0267?
Yes, but fix soon. C0267 is rated serious severity. It is not an immediate stop-driving fault, but it will not clear itself — book the repair rather than ignoring the light.
Frequently Asked Questions
What does C0267 mean?
C0267 is a chassis code used primarily by GM vehicles: ABS Pump Motor Circuit Open/Shorted. It concerns the ABS/traction control system.
Can I keep driving with C0267?
Base brakes keep working, but assume ABS and stability control are offline until repaired - allow longer stopping distances and drive gently, especially in rain or snow. Repair promptly.
Is C0267 the same on every make?
The decimal C0xxx range is dominated by GM's assignments (Chevrolet, GMC, Buick, Cadillac). Other makes may use this ID differently - if your vehicle is not a GM product, verify the meaning in your make's service information.

How Do You Diagnose C0267?
-
Read the code with a GM-capable scan tool and note the symptom byte/subcode if shown.
-
View live data for the named circuit (e.g. all four wheel speeds while rolling for wheel-speed codes).
-
Inspect the circuit's wiring and connectors - chassis harnesses live in the splash zone and corrode first.
-
Follow the GM pinpoint test for C0267 before replacing components.
