3. 3

   Verify the voltage supply to the armrest controller; check for a blown fuse or low voltage which can trigger erratic switch codes.

4. 4

   Check the CAN bus terminators located inside the armrest (especially on older models with active terminators) for broken solder joints on the circuit board.
