What does this fault code mean?
The transmission control module (TCM) has detected that the voltage to the electric transmission oil pump is too high. The pump supplies the gearbox with the right pressure and flow while automatic engine start/stop is active, and the control module can switch it off when the start/stop function is disabled. The fault is general and does not say more precisely what type of fault it is.
Possible causes
- Voltage too high
- Damaged system relay
- The connector or cable to the pump is damaged
What you can do
- 1Read and note the fault code, clear it and drive the car to see if it returns
- 2Check that the connectors to the oil pump and system relay are not oxidized or loose, and that the cables are undamaged
- 3Have a workshop check the system relay for damage and power supply, and the voltage cable to the oil pump for an open circuit
Symptoms you may notice2
- Automatic engine start/stop does not work while driving
- Automatic engine start/stop does not work at idle
