The measurement value is not OK.Possible cause and remedy
- Line between component A1 (Instrument cluster) and component N10/1 (Front SAM control unit with fuse and relay module)
- Lines between A1 (Instrument cluster) and W28/1 (Ground, left inner door sill)
- Perform inspection of connector and of socket for bent pins and enlarged contacts.
End of test
1.1.3.2.1.2. Check power supply at control unit A89 (DTR controller unit).
