How much does ABS module repair cost?

ABS module repairs range from $150 for wiring or relay fixes to $800-$1,200 for a full ABS control module or hydraulic pump replacement. Remanufactured modules can reduce costs significantly.

Can a low battery cause ABS and traction control warnings?

Yes, low battery voltage is a common cause of ABS and traction control warning lights. The ABS module requires stable voltage to operate correctly. A weak battery or failing alternator should be tested first.

C0124

Power Steering Motor Overtemperature

Moderateelectrical

Overview

The C0124 code indicates that the chassis control module has detected a power steering motor overtemperature condition. This diagnostic trouble code relates to the electrical control circuits within the vehicle's chassis safety systems, including ABS, traction control, and stability control. When this code is stored, one or more chassis safety features may be disabled, which can reduce braking performance and vehicle stability under adverse driving conditions.

Symptoms

ABS warning light illuminated on dashboard
Loss of stability control function
Traction control warning light on
Suspension ride quality noticeably degraded

Common Causes

Poor ground connection at the ABS module
Failed ABS hydraulic pump motor
Damaged suspension control module
Corroded or damaged wiring in the ABS harness

Diagnosis Steps

1Connect an OBD-II scanner and read all stored chassis trouble codes and freeze frame data
2Inspect the ABS/ESC module connectors for corrosion, damage, or loose pins
3Check the ABS fuse and relay in the fuse box; replace if blown or faulty
4Test the ABS pump motor operation using a scan tool bi-directional command
5Measure circuit voltage and ground at the ABS module with a multimeter

Estimated Repair Cost

$150 — $1,200

Cost varies by vehicle, location, and repair shop. Includes parts and labor.

Frequently Asked Questions

Your standard brakes will still work, but the anti-lock braking function is disabled. This means wheels can lock up during hard braking, especially on wet or icy roads. Avoid aggressive driving and have the system inspected promptly.
