NO
Preconditions
- It is not possible to turn the pulse ring.
NOTE
- No further action is necessary.
End of test
NO
The measurement value is not OK.Possible cause
- Wiring harness between transmission and component N15/3 (ETC [EGS] control unit) is jammed or damaged because of a chafing point.
- Wiring harness has dropped off from control module N15/3 (ETC [EGS] control unit) or has not been correctly plugged in after completing repairwork.
- Discontinuity in line from control unit N15/3 (ETC [EGS] control unit) and component Transmission.
- Component Y3/6n2 (speed sensor 2) is defective.
Possible remedy
- Inspect wiring and plug connections between Transmission and control unit N15/3 (ETC [EGS] control unit) for corrosion, loose contacts and damage.
- Repair wiring.
