What does this fault code mean?
The code is a general fault on the signal wire of the starter relay, where the voltage is too high. The engine control module sets it when the voltage stays above a set threshold for a set time. It is checked when the engine is started.
Possible causes
- Signal wire shorted to voltage
- Damaged starter relay
- Damaged control module
What you can do
- 1Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
- 2Use a multimeter to check that the signal wire has no break and is not shorted to earth or to the battery positive
- 3Check that the connectors at the starter relay and in the wiring are firmly seated and free from play, oxidation and contact resistance
- 4Check that the starter relay is intact and firmly fitted in its mounting
- 5If the fault remains after these checks, have a workshop investigate the engine control module
Symptoms you may notice1
- The engine does not start, either always or on some occasions
What the fault can affect1
- Only manual starting is possible
