This is the range for the most common fix, abs control module repair or replacement. Which repair your car needs depends on a proper diagnosis.
The ABS computer sees a problem with the pump motor circuit, meaning the motor may not run when asked or draws the wrong amount of current. Power, ground, the relay and the motor itself are all possible causes. The exact meaning varies by make, so check the scan tool or manual.
- Safe to drive?
- Short trips only
- Most common cause
- Failed ABS pump motor
Normal brakes usually still work, but without ABS help the wheels can lock in a hard stop, so leave extra room and brake early.
What you may notice
- ABS light on
- Traction control light on
- No pump buzz when ABS activates
- Stability control off
Common causes, most likely first
- Failed ABS pump motor
- Bad relay or blown fuse
- Corroded connector or ground
- Low battery voltage
- Failing ABS module
Check this first
Check the ABS fuses first, then the battery and ground points. A shop can also listen for the pump during a test and measure its power with a scan tool, which tells them if the motor runs or if power is not reaching it.

C0110 questions
Do I need a whole new module?
Often the pump is part of the module, but some shops rebuild them, or sell the motor separately. Ask for your options, with prices, before agreeing to a full module replacement.
Will brakes fail?
No. The regular brakes keep working. You lose anti-lock and stability help, so leave extra stopping distance and brake early, especially on wet roads, until the pump circuit is repaired.
Is it a battery problem?
It can be. Low battery voltage can set a pump circuit code, since the pump needs a strong feed to start. Test the battery and the charging system before you accept a pump or module repair.
How much does it cost to fix C0110?
The most common fix, abs control module repair or replacement, has a typical range of $550 to $1,775 in Boston. It is an estimate built from parts prices and local labor wages, not a quote. Your car and shop change it.
