What does this fault code mean?
The code means that the CAN signal from the TCM says starting is allowed, while the signal on the wire from the gear selector says the opposite. The engine control module monitors this to decide whether engine start is allowed, and the fault is checked with the ignition on.
Possible causes
- The root cause is in the transmission control module (TCM)
What you can do
- 1Look for the root cause in the transmission control module (TCM): read off and remedy its fault codes there first
- 2Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
- 3If you have a diagnostic tool, check in live data that the selector position agrees with the CAN signal as you move the selector between P/N and other positions
- 4If the fault remains, have a workshop investigate the TCM, where the cause is given as lying
Symptoms you may notice2
- The starter drags the engine round slowly and it starts with difficulty
- The engine does not start, at some times or all the time
What the fault can affect1
- The ECM uses the signal received over CAN instead
General guidance for car owners. Diagnosis on the car can point to a different cause.
