SeriousSeverity: Serious - have it checked soon
Transmitting and receiving problems on CAN IS network
Key terms: Control module: a small computer that runs one part of the car
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?
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.
