SHIFT LOCK SYSTEM

With ignition on, when brake pedal is depressed, an input signal is sent from brakelight switch to ECU. With shift lever in Park, an input signal from shift control switch is input to ECU, indicating shift lever is in Park. ECU then operates shift lock solenoid, so shift lever can be moved from Park.

KEY LOCK SYSTEM

With ignition in ON or ACC position and shift lever in Park, shift lock control switch opens and voltage from ECU to key interlock solenoid is turned off. When key interlock solenoid is turned off, ignition key can be turned from ACC to LOCK position on ignition switch.

COMPONENT TESTS

Note. If ignition is left in ACC or ON position with shift lever in any gear range except Park for about one hour, ECU then operates to release lock mechanism.

ELECTRONIC CONTROL UNIT (ECU)

Access ECU. see scheme 1 ECU is under center console, in front or back of shifter. Turn ignition on. Backprobing ECU harness connector with DVOM, check voltage between designated terminals. Voltage should be as specified. See appropriate SHIFT LOCK SYSTEM PIN VOLTAGES table. For circuit identification, see appropriate wiring diagram in WIRING DIAGRAMS.

Note. Ground (GND) terminal is also referred to as "E" terminal.
