Car models equipped with automatic transmissions are equipped with interlocking systems. The interlock system consists of two subsystems: the gearshift lever interlock system and the ignition switch interlock system.
The ignition lock system prevents the key from being removed from the ignition switch unless the gear shift lever is in the park position.
The gearshift lever lock system prevents the lever from being moved from the park position to any other position unless the brake pedal is depressed.
The shift lever lock system consists of a transmission sensor, a shift lever lock mechanism, a parking switch, a brake pedal switch, an ignition lock cable, and an emergency lock switch.
Examination
Gear shift lever lock mechanism
1. Check the 15A METER and 20A STOP fuses. Replace the fuses if necessary and check the circuit from the locking mechanism to the fuse box.
2. Remove the center console.
3. Place the gear shift lever in the park position.
4. Remove the shift lever position indicator panel.
5. Disconnect the 4-pin connector from the locking mechanism (arrow).
6. Turn on the ignition. When connected to pin 2, the voltmeter should show battery voltage. If this is not the case, check the ignition switch circuit.
7. Turn off the ignition. When connected to pin 1, the voltmeter should show battery voltage. If not, check the 20A STOP fuse circuit.
Parking position switch
8. Determine the location of the switch connector (C – parking switch wire connector, B – locking mechanism, A – emergency locking switch).
9. Connect the ohmmeter to the contacts of the switch socket. The circuit must be closed.
10. Place the gear shift lever in any position other than park. The switch circuit must be open in all other positions.
11. Replace the switch if necessary.
Replacement of elements

2. Disconnect the wire from the mechanism.
3. Remove the two screws and two nuts of the locking mechanism.
4. Remove the mechanism.
5. Installation is carried out in the reverse order of removal.
Ignition lock cable
6. Remove the center console.
7. Remove the four gear shift indicator screws and remove the indicator.
8. Loosen the cable locknut.
9. Disconnect the cable from the bracket.
10. Remove the lower part of the instrument panel.
11. Remove the upper and lower steering column covers.
12. Unscrew the cable screw and remove its bracket.
13. Disconnect the cable from the ignition lock cylinder.
14. Remove the cable.
15. Installation is carried out in the reverse order of removal.
