Warning! Cars are equipped with security systems (SRS), including airbags and seat belt tensioners. Before carrying out work near the shock sensors, the instrument panel and the steering column, first disconnect the negative and then the positive terminals from the battery and wait about two minutes. This will prevent the airbags from deploying unintentionally and the seat belt pretensioners from deploying, which could cause injury.

The locking system of the selector lever and the ignition lock prevents the selector lever from moving from positions «P» and «N», if the brake pedal is not pressed (pic. 9.25, 9.26, 9.27). It is also impossible to remove the key from the ignition if the selector lever is not in its original position.
Checking the key interlock solenoid in the ignition lock
Remove the steering column cover.
Disconnect the electrical connector from the key interlock solenoid in the ignition switch.
Using an ohmmeter, measure the resistance of the solenoid winding, which should be in the range of 12.5–16.5 ohms.
Using additional wires, briefly apply battery voltage to the contacts of the solenoid winding, while it should make a clicking sound. Do not apply voltage for a long time, as the solenoid may be damaged.
If any of the checks fail, replace the solenoid.
Checking the selector lever lock solenoid on 1996 and 1997 models
Remove the center console.
Disconnect the electrical connector from the selector lever lock solenoid.
Using an ohmmeter, measure the resistance of the solenoid winding, which should be in the range of 26–33 ohms.
Using additional wires, briefly apply battery voltage to the contacts of the solenoid winding, while it should make a clicking sound. Do not apply voltage for a long time, as the solenoid may be damaged
If any of the checks fail, replace the solenoid.
Checking the Selector Lever Position Control Switch on 1996 and 1997 Models
Pic. 9.28. Connecting ohmmeter probes when checking the selector lever position switch: P1, P, P2 - switch contacts
Disconnect the electrical connector from the switch and use an ohmmeter to measure the resistance between the contacts in each position of the selector lever (fig 9.28). Switch states are shown in Table 9.4.
If the resistance between the contacts is not within specification, replace the switch.
Blocking system control unit
If the above components are OK and the locking system is not working properly, the locking system control unit is probably defective and needs to be replaced. However, before replacing the unit, check the electrical circuits between the components of the locking system for breaks and short circuits.
