What it means

Another module, such as the engine computer, transmission module or instrument cluster, is receiving messages from the ABS module over the network, but their content is invalid, most often wheel speeds and vehicle speed. The cause is usually a faulty wheel speed sensor or a problem in the ABS module itself, so ABS codes are read first.

Symptoms4

ABS, traction control (TCS) and stability lights on.
Speedometer not working or erratic on some vehicles.
Abnormal shifting or transmission limp mode.
Cruise control disabled.

Possible causes5

A faulty wheel speed sensor or its wiring, with its own code in the ABS module.
Incorrect programming or coding of the ABS module after replacement.
Low battery voltage.
Intermittent fault in the network wiring or ABS module connector, especially with water or corrosion.
Internal ABS module failure.

How to diagnose5

Read the ABS module codes first and fix any wheel speed sensor or module codes.
Watch each wheel speed on a scan tool during a road test and look for an odd or dropping reading.
Measure battery and charging voltage.
Check whether the ABS module was replaced recently and confirm it is coded correctly.
Inspect the ABS module connector and network wiring for corrosion or water.

How to fix6

Repair the wheel speed sensor wiring or replace the faulty sensor.
Charge or replace the battery.
Clean or repair the ABS module connector.
Recode or reprogram the ABS module with the correct version.
Replace and program the ABS module if proven faulty.
Clear the codes, road test and confirm the lights stay off and the code does not return.

In Saudi riyals; the highlighted part is the expected range for this fault.

The cost is low for a wheel sensor, its wiring or coding, and reaches the upper end if the ABS module must be replaced.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions

Do the brakes still work with this code?

Yes, normal braking works, but ABS and stability control may be disabled, so wheels are more likely to lock and skid under hard braking.

Why are the speedometer or transmission affected?

On many vehicles, vehicle speed is calculated from the wheel speed sensors in the ABS module. If that data is invalid, the modules that rely on it are affected.
