Shift Interlock System

Shift interlock system prevents shift lever from being moved from Park unless brake pedal is depressed and accelerator pedal is in idle position. In case of a malfunction, shift lever can be released by placing ignition key in key 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 ECU from brakelight switch. With accelerator pedal in idle position, a low voltage is applied to the ECU from the throttle angle sensor. The ECU then supplies voltage to shift lock circuit in the interlock control unit. When shift position console 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 located on side of shift lever. See Figure . Interlock control unit is located behind driver's side of instrument panel and contains an 8-pin connector. Shift position console switch is mounted on driver's side of shift lever.
