Note: the test is carried out with the ignition key in the ON position and the automatic transmission selector in the position "R".
1. Disconnect the automatic transmission selector connector.
2. Turn on the ignition, short the leads on the wiring harness side and check that the corresponding indicator on the instrument cluster is on.
Note: check that when switching the automatic transmission selector to the position "R" the corresponding indicator on the instrument cluster lights up and a buzzer sounds.
