Checking the ignition switch
If the conductivity does not match the table, replace the ignition switch.
Checking the sensor for a key left in the lock
1. Check for continuity between terminals "1" and "2" of the connector when the sensor is in the "ON" position (the key is inserted).
2. Check for continuity between terminals "1" and "2" of the connector when the sensor is in the "OFF" position (the key is removed). If the conductivity differs from the description, replace the switch.
Testing the key left in lock warning system (models since 1996.)
1. Check the operation of the integrated relay.
- a) Connect the battery to terminals "1" (+) and "5", "6" and "10" (-).
- b) Check for the presence of a sound signal.
- c) Disconnect the negative wire from terminal "6".
- d) Check that the sound signal has turned off.
- d) Connect the negative battery cable to terminal "6".
- e) Disconnect the negative wire from terminal "5".
- g) Check that the sound signal has turned off.

If operation differs from description, replace relay.
2. Check the relay circuit.
Disconnect the relay from fuse box #1 and check the circuit from the box side according to the table.
If the circuit matches the description, replace the relay.
If the circuit does not match the description, look for a fault in other elements.
