Software Incompatibility With Anti-Lock Brake System (ABS) Control Module

24 brands affected · Generic SAE J2012 description.

Key terms: ABS: anti-lock braking, which stops the wheels locking · Control module: a small computer that runs one part of the car · SAE J2012: the standard generic code list

Safety: This code relates to the braking system or brake assist. Braking may be affected.

1What it means in plain English

Control modules in the car cannot communicate with each other over the vehicle network.

2Common causes

Wiring or connector fault on the communication bus
Faulty control module
Low battery voltage or poor ground
Water ingress in a connector or module
Aftermarket device interfering with the bus

3Can I drive?

Serious · drive with care

The car may run normally or may not run at all. If the module that has lost communication controls steering, brakes, park brake, charging or engine cooling, drive only if those systems feel normal; stop safely if the steering becomes heavy, a brake warning appears, or the engine temperature climbs. If the car will not start or runs badly, have it towed.
