Location of selector locking system nodes
1. Key lock solenoid; 2. Selector lock solenoid; 3. Selector control unit; 4. Selector lock switch; 5. Brake light switch
The system ensures that the selector is fixed in the Park or Neutral positions when the brake pedal is pressed. All maintenance work on the system, except for those described below, is performed at a car service center.
Examination
1. To access the system components, the floor section must be removed.
2. Disconnect the connector and apply battery voltage to the terminals of the selector lock solenoid. If there is no characteristic click, replace the solenoid.

3. Disconnect the key lock solenoid connector and check the resistance between terminals 1 and 5 (left figure – for cars of 1991-95), between terminals 7 and 8 (right figure – for cars of 1995 and later), which should be 12–17 Ohms.
4. Disconnect the connector from the selector lock switch and check the resistance between the indicated terminals.
5. In the Park selector position, there should be a circuit between terminals P and P1.
6. When the selector is in the Park position and the button is pressed, there should be a circuit between terminals P and P1 and P and P2.

7. In the remaining selector positions R, N, D, 2 and L there should be a circuit between terminals P and P2.
8. If the test results differ, replace the faulty parts and repeat the tests.
