Shift Interlock Systems: Other Mazda MX-5 NB

SHIFT LOCK SYSTEM

With ignition on, brake pedal depressed, and park position switch on, an input signal is sent from brakelight switch to the actuator. The shift lock actuator will then operate the lock lever (release position), so shift lever can be moved into Park.

FUNCTIONAL CHECK

1. With ignition key removed, ensure gear selector cannot be moved from Park. Insert key in ignition switch.
2. Turn ignition on. Ensure gear selector can only be moved with brake pedal pressed down. Move gear selector to Reverse.
3. Ensure ignition key cannot be removed, Move gear selector to Park. Ensure it is not possible to remove ignition key.
4. If shift lock system does not operate as described, check gear selector, shift lock solenoid and control cable.
5. Place gear selector in Park. Using a screwdriver, push down emergency override button on shifter console and verify gear selector can be moved from Park position. (Scheme 79)and (Scheme 80). If gear selector cannot be moved out of Park, adjust or replace shift lock actuator.

Scheme 80

Miata

Disconnect negative battery cable. Remove rear console. Remove indicator screws and lift up panel. Disconnect park position switch. Check continuity between connector terminals. (Scheme 81) Continuity should exist with switch released. Continuity should not exist with switch depressed. Replace as needed.

Scheme 81

Millenia

Disconnect negative battery cable. Remove rear console and center panel. Remove indicator screws and lift up panel. Disconnect park position switch. Check continuity between terminals "k" and "h". (Scheme 82) Continuity should exist with switch released. Continuity should not exist with switch depressed. Replace as needed.

Note. Test procedures are not available.

1. Remove rear console. Remove selector knob and indicator panel screws. Lift up selector lever, selector sleeve and indicator. Disconnect HOLD switch connector. Ensure selector lever is in Park position.
2. Turn ignition on. Check voltage at selected connector terminals. (Scheme 81) If voltage is not as specified, inspect harness and connector. Repair as needed. If harness and connector is okay, replace shift lock actuator.
3. Turn ignition off. Check continuity at selected connector terminals. If continuity is not as specified, inspect harness and connector. Repair as needed. If harness and connector is okay, replace shift lock actuator.
