Causes
- Blown fuse or faulty ABS pump relay
- Open or shorted wiring to the ABS pump motor (corrosion, broken conductor, damaged insulation)
- Poor or corroded electrical connector at pump motor or ABS module
- Failed ABS pump motor or internal pump assembly fault
- Faulty ABS control module or driver stage inside the module
- Low battery voltage or poor chassis/engine ground
Symptoms
- ABS warning lamp illuminated (may be steady or flashing)
- Traction control/ESP disabled message
- ABS pump may run continuously, not run when commanded, or make abnormal noise
- Reduced or lost ABS function during braking (longer stopping distances under ABS conditions)
- Possible changes in brake pedal feel when ABS engages
- Possible stored additional ABS or communication fault codes
What to check
- Scan and record all stored and pending codes, freeze frame and freeze data
- Visual inspection of ABS pump, connectors and wiring for corrosion, damage or water ingress
- Check ABS-related fuses and relays for continuity and correct operation
- Check battery voltage and main grounds, ensure charging system healthy
- Use a scan tool to command/monitor pump motor operation and observe module status
- Measure supply voltage at pump connector with command active and inactive
Signal parameters
- Battery supply voltage at pump connector: ~12–14 V with ignition ON (13.5–14.5 V when engine running)
- Pump motor supply when commanded: battery voltage present on supply pin (check using fused jumper only for tests)
- Motor winding resistance (approx): typically low ohms (may vary by model) — expect a few ohms to tens of ohms; open/very high indicates open winding
- When commanded OFF: no voltage on motor control pin(s) and near-zero current draw
- When commanded ON: increased current draw (amperes); excessive current indicates mechanical seizure or internal short
Diagnostic algorithm
- Read and record ABS and network codes with a capable scan tool. Note any related communication or voltage faults.
- Perform a visual inspection: connectors, loom, signs of corrosion/water, damaged insulation, and clamp points.
- Check fuses and pump relay. Replace suspect items and re-check codes.
- With ignition ON, use scan tool to attempt pump activation while monitoring supply voltage at the pump connector.
- Measure continuity between ABS module motor output pin(s) and pump motor connector; check for shorts to ground or battery.
- With ignition OFF, disconnect pump connector and measure motor winding resistance across motor pins. Compare to specification or look for open/short.
- If wiring and connectors are good, bench-test the pump motor by applying fused 12V directly to the motor (observe current draw and safe test practices). If motor does not run or draws excessive current, replace pump assembly.
- If motor and wiring test OK, suspect ABS control module driver fault; verify module supply/grounds and CAN communication. Consider module replacement or repair following manufacturer procedures.
- After repair or replacement, clear codes, perform ABS system self-tests and bleed/calibrate brake/ABS as required. Road test to confirm fault absence.
- Safety note: When applying direct power use a fuse and limit testing duration. Follow manufacturer safety and repair procedures when removing/replacing ABS components.
Likely causes
- Corroded/loose connector at ABS pump motor
- Blown fuse or faulty pump relay
- Pump motor seized or electrically failed
- Open/short in harness between ABS module and pump
- Faulty ABS module driver (less common)
Fault status
Status
ABS pump motor circuit fault detected — possible open/short, excessive current, or pump motor failure. ABS functionality may be disabled.
Repair difficulty: Medium
Diagnostic time: 1.5-3.0 hours
