What does this fault code mean?
On some occasions the ABS control module has not received the supply from its main relay function to the valves. Without that supply the valves cannot be controlled and ABS is blocked. The fault is intermittent. Because the vehicle speed signal from the ABS module is also lost, the instrument cluster, central electronic module and gearbox can be affected.
Possible causes
- Contact resistance in the connections
- Blown fuse in the supply to the valves
- Faulty ABS control module
- Intermittent open circuit in the wires between the fuse and the module
What you can do
- 1Check the wires between the fuse in the engine bay relay and fuse box and the module for intermittent open circuits
- 2Check that the fuses in the supply are intact
- 3Check the ABS control module connector for contact resistance and oxidation
- 4If the fault remains, have a workshop with diagnostic equipment trace the supply; replace the module only once the wiring has been investigated
- 5ABS is safety-critical – do not work on the ABS control module or the brake system yourself, have a workshop do it
