SHIFT & KEY INTERLOCK SYSTEMS
Shift Interlock System
Shift interlock system prevents shift lever from being moved from Park unless brake pedal is depressed and accelerator is in idle position. In case of a malfunction, shift lever can be released by placing ignition key in release slot near shift lever. Voltage is provided to shift lock solenoid when ignition is on.
When brake pedal is depressed, battery voltage is applied to the TCM from brakelight switch. With accelerator pedal in idle position, a low voltage is applied to the TCM from the throttle position sensor. The TCM then supplies voltage to shift lock circuit in the interlock control unit. When A/T gear position switch is in Park position, interlock control unit then operates shift lock solenoid by controlling the ground circuit. When shift lock solenoid is energized, shift lever is released and can be moved.
Shift lock solenoid is mounted on driver's side of shift lever. See Fig. 2 and Fig. 3 . The A/T gear position switch is located on side of shift lever. Interlock control unit is located above driver's side kick panel and contains a MD7Gray 8-pin electrical connector.
Key Interlock System
Key interlock system prevents ignition key from being removed from ignition lock assembly unless shift lever is in Park. Voltage is provided to key interlock switch from No. 46 fuse (15-amp) in engine compartment fuse box. Engine compartment fuse box is located on passenger's side rear corner of engine compartment, near firewall. When ignition key is installed in ignition lock assembly, key interlock switch closes, providing voltage to key interlock solenoid and interlock control unit.
If shift lever is not in Park, interlock control unit activates key interlock solenoid by completing the ground circuit, preventing ignition key from being removed from ignition lock assembly. Key interlock switch and solenoid are located on ignition lock assembly. See Fig. 2 and Fig. 3 . Interlock control unit is located above driver's side kick panel and contains a MD7Gray 8-pin electrical connector.
