What you can do

1Read off the fault code, clear it and road test the car to see whether it comes back
2Have a diagnostic tool? With the engine running in P, read the STH current; if it does not fall as the accelerator is pressed slowly, the control module is faulty
3Have a workshop replace the control module and program the new one, since a replacement arrives without software

Symptoms you may notice5

Malfunction indicator lamp (MIL) on

No gear changes

What the fault can affect2
