Cause:
Contact between interior wiring harness and steering column tube switch module (steering column tube switch module connector no.1), see attachment 1, item "1"
The exact cause is still being analyzed.
Remedy:
Check resistance of ignition circuit using XENTRY Diagnostics:
SRS control unit -> Ignition circuits -> Airbags for driver and front passenger -> Actual values
If one of the actual values is in the upper specified value range -> Further tests as described in Xentry DAS.
If the actual values are OK -> Replace the contacts between the interior wiring harness and the steering column tube
switch module (attachment 1, item "1"):
1.) Replace contacts
- Create access to connector and separate from steering column tube switch module - See AR54.25-P-2802NKB Remove/install steering column tube module
- Cut cable tie directly at guide of connector (see attachment 2, item "3").
- Open secondary lock of connector (see attachment 2, item "4").
Important: Repair each line individually in order to avoid mixing up the lines.
