What does this fault code mean?
Position sensor 2 in the rear roof section receives too low a voltage on its signal wire when the control module is to activate it. This points to the wire being short-circuited to ground. The roof may then be operated only in a limited way or not at all.
Possible causes
- The wire is short-circuited to ground
What you can do
- 1With the ignition off, look for chafing or damage on the signal wire to position sensor 2 in the rear roof section.
- 2Use a multimeter to check that the signal wire is intact and has no contact with ground (the body). If it has contact or a break, the wire must be repaired.
- 3Check the connector at position sensor 2 and at the control module for contact resistance, oxidation and looseness. Clean or tighten it.
- 4If the wire and connectors are in order, have a workshop replace position sensor 2.
Symptoms you may notice1
- No or limited roof operation
