EBCM Pump Motor Stalled
What does C0267 mean?
The C0267 code means the vehicle's onboard diagnostic system has detected: EBCM Pump Motor Stalled. This is a critical severity code.
Common Symptoms
- ABS warning light on
- Grinding or groaning noise from ABS area
- ABS does not function during hard braking
- Traction control inoperative
- Burnt smell from the ABS module area
Probable Causes (Ranked by Likelihood)
- ABS pump motor seized or mechanically jammed Very High
- Contaminated brake fluid causing hydraulic blockage High
- Excessive moisture in brake fluid causing internal corrosion Moderate
- Pump motor winding failure Moderate
- ABS modulator internal hydraulic failure blocking pump Low
Step-by-Step Diagnostic Procedure
-
Listen for the pump motor attempting to run -- grinding or buzzing indicates a stall
-
Check brake fluid condition and level
-
Test pump motor for excessive current draw indicating a mechanical jam
-
Try tapping the ABS module while commanding the pump to see if it frees up
-
Verify power and ground at the pump motor connector are adequate
Frequently Asked Questions
What causes an ABS pump motor to stall?
The most common cause is internal corrosion from moisture-contaminated brake fluid. This corrosion can seize the pump or block hydraulic passages, preventing the motor from turning.
Can a brake fluid flush prevent pump motor stalling?
Yes. Regular brake fluid changes every 2-3 years remove moisture that causes internal corrosion. This is one of the most effective preventative maintenance items for the ABS system.
Can the pump motor be replaced separately from the modulator?
On some vehicles the pump motor is replaceable separately. On others, the motor and hydraulic modulator are one integrated assembly. Check parts availability for your specific vehicle.
