OBD-II trouble code
C0267: Pump Motor Circuit Open
The ABS module detected an open (broken) circuit in the anti-lock brake pump motor. ABS, traction, and stability control are disabled, but your normal (base) brakes still work.

What does C0267 mean?
The anti-lock brake system uses an electric pump motor in the hydraulic control unit to build and move brake fluid pressure during ABS, traction, and stability events. The electronic brake control module (EBCM) drives this motor and watches its feedback voltage to confirm it is connected and responds when commanded. C0267 specifically means the module sees an open circuit — an electrical break — in the pump motor path: the motor windings, the high-current wiring, or the internal driver has lost continuity, so no current can flow.
With an open pump-motor circuit the module cannot run the pump at all, so it disables ABS, traction control, and stability control and lights the warnings. Your ordinary hydraulic brakes are not powered by this motor, so the vehicle still stops when you press the pedal, but the anti-lock and stability functions are offline until the fault is repaired.
Because the pump motor is usually integral to the EBCM/hydraulic control unit, an open inside the motor windings or the module's driver typically means replacing or rebuilding the unit. Before that, though, an open circuit can also be a broken or corroded high-current connection, a backed-out connector pin, a blown fusible link, or a bad ground — all cheaper fixes. C0267 (open) is the companion of C0268 (shorted); the two describe opposite electrical failures of the same pump-motor circuit, and either one, especially alongside C0265, points toward EBCM trouble. Confirm the module's power, ground, and connector integrity before condemning it.
Common causes
- Open pump-motor windings inside the EBCM/hydraulic unit
- Broken, corroded, or disconnected high-current pump wiring
- Backed-out or corroded terminal at the EBCM connector
- Blown fusible link or ABS pump fuse
- Failed internal pump-motor driver circuit within the EBCM
- Poor high-current ground connection
Symptoms
- ABS warning light on
- Traction control and stability control (ESC) warning lights on
- ABS, traction, and stability features disabled
- Normal (base) braking still works
- No ABS pump self-test sound at key-on on some vehicles
Diagnostic steps
- 1.Scan the ABS module and record C0267 plus any companion codes (C0265 and C0268 often accompany it).
- 2.Check the ABS pump fuse and any fusible link in the high-current feed.
- 3.Inspect the EBCM connector and the pump-motor power and ground terminals for corrosion, damage, or a backed-out pin.
- 4.Perform a voltage-drop and continuity test on the pump-motor power feed and ground to locate the open.
- 5.Command a pump self-test with a capable scan tool and watch feedback voltage; no response with an open reading confirms the fault.
- 6.If the wiring, connector, fuse, and ground are all good and the motor circuit is still open, the EBCM/pump assembly is the likely fix and typically needs replacement or rebuild with programming.
Repair cost
$250 – $1,200
When the open is in the wiring, a connector terminal, or a fusible link, the repair can be modest. When the open is inside the pump motor or the EBCM's driver — the more common case — the fix is EBCM/hydraulic-unit replacement or rebuild plus programming, commonly $500-$1,200 at a shop. Mail-in module rebuild services can lower the parts cost to roughly $150-$300.

DIY vs shop
This is an advanced DIY job. It typically requires specialty tools, scan-tool access, lifting equipment, or careful sequencing to avoid causing new failures. Plan for extended downtime and have a backup vehicle. Most owners are better served by a shop that has done this repair before.
