ABS Pump Motor Circuit Failure

Issue with the ABS pump motor circuit detected.

Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.

What it means (plain English)

The ABS computer is telling you that there's a problem with the circuit that powers the pump, which helps the brakes work properly during slippery conditions.

What the computer is actually seeing

The ABS control module monitors the voltage and current in the pump motor circuit. If it sees abnormal readings, like too low a voltage (under 10V) or an open circuit, it sets this code.

What a healthy reading looks like

Expected voltage at the pump motor circuit should be between 10V to 14V, with a current draw typically around 3A when operating.

Guided diagnostic — the DiagCoach way

Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.

  1. 1Check the ABS system fuse for continuity and replace if blown.
  2. 2Inspect the wiring and connectors to the ABS pump motor for any damage or corrosion. Repair or replace as needed.
  3. 3Using a multimeter, measure the voltage at the ABS pump motor connector with the key on, engine off. If below 10V, investigate power supply issues.
  4. 4Check the pump motor itself for resistance; it should be around 3-10 ohms. If it reads infinite resistance, replace the motor.
  5. 5If the motor is functioning and the wiring is intact, test the ABS control module for failure.

Common causes

  • Damaged wiring or connectors in the ABS pump motor circuit
  • Faulty ABS pump motor
  • Defective ABS control module

Frequently asked questions

Is it safe to drive with this code?

It's drivable, but your ABS won't work properly, which may affect braking on slippery roads. Fix it soon.

Will this code come back after clearing?

If the underlying issue isn't resolved, yes, the code will reappear.

Why does this code sometimes pair with other ABS codes?

Related ABS codes indicate problems within the same system, often caused by similar wiring issues or component failures.
