P2098

The crash signal from component N2/7 (Restraint systems control unit) is implausible.

Test 1: Test voltage level on crash signal wire.

1. Test voltage level on crash signal wire.
Test prerequisite

- Fault code 'P2098' present
Test sequence

- Switch off ignition.
- Connect socket box (126-pin) to component N3/10 (ME-SFI [ME] control unit).
- Connect socket box (35-pin) to component N3/10 (ME-SFI [ME] control unit).
- Measure direct voltage with multimeter between socket (5.5) 5 of the 35-pole socket box tester and socket (4.20) 105 of the 126-pole socket box tester.
- Switch on ignition.
Specified value

- Voltage<1 V
Question

- Is the measurement value OK?


YES
The measurement value is OK.Further possible causes of fault

- Fault in control unit AB: Read out fault memory of control unit N2/7 (Restraint systems control unit).
End of test

NO
The measurement value is not OK.Possible cause and remedy

- Line from component N2/7 (Restraint systems control unit) to component N3/10 (ME-SFI [ME] control unit)
- Read fault memory from control unit AB and rectify faults.
