What does this fault code mean?
The rear door module on the passenger side powers the child safety lock motor. The control module has registered that the signal from the output is too high when the child safety lock is activated. The fault may be caused by the supply cable being short-circuited to supply voltage or having an open circuit, and then the child lock does not work.
Possible causes
- Power supply cable short-circuited to supply voltage
- Open circuit in the power supply cable
What you can do
- 1Check that the relevant fuses are intact
- 2Test the child lock in the rear door and note whether it responds
- 3Use a multimeter to check that the supply wire to the child lock motor has neither an open circuit nor contact with supply voltage
- 4Look for damage, chafing and loose connections in the wiring to the rear door
- 5Remedy as needed, then check that the child lock works afterwards
