Checks to be carried out if fault is present
Not specified (short circuit to earth or short circuit to positive or open circuit)
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| after a starting test | check: ignition on, ECU connected: - no voltage at terminal(s) B1, B2 of the control unit 32 V.GR ignition off: control unit disconnected: - no earth at terminal B1, B2 on the 32 V.GR connector (control unit) - R = 199,9 k Ω between terminals A2 and B2 of the control unit connector 32 V.GR - 360 Ω ≤ R ≤ 460 Ω between terminals B1 and B2 of the control unit connector 32 V.GR |

| after a starting test | check: check the consistency of the signal perceived by the ECU (parameter measurements): |
Check(s) to be carried out if no fault found
Correct fitting
Do not create any (hammer) impact in the engine environment, with the engine running: there is a risk of interference to the signal
