Examination
Check the operation of the lock switch, making sure that the engine starts only when the selector lever is in the positions «parking» or «neutral».
Trace the wire from the switch to the connector and disconnect the connector.
Using an ohmmeter, measure the resistance between the switch terminals, it should tend to infinity (gap) in the provisions «reverse», «parking» And «neutral».
Pic. 9.25. Interlock switch pin arrangement
With the ignition on and the selector in the marked positions, there should be no gap between the following contacts (pic. 9.25):
- «A» And «IN» (parking);
- «WITH» And «D» (reverse);
- «A» And «IN» (neutral).
Replacement
Disconnect the connector and remove the lock switch from the gearbox housing. Installation is carried out in the reverse order of removal. Apply sealant to the threads of the switch before installation.
