SHIFT LOCK SYSTEM
With ignition on, when brake pedal is depressed, an input signal is sent from brakelight switch to the ECU. With shift lever in Park, an input signal from shift control switch is input to ECU, indicating shift lever is in Park. The ECU then operates shift lock solenoid, so shift lever can be moved from Park.
KEY LOCK SYSTEM
Note. On Corolla models, key lock system uses a cable for system operation. On all other models, key lock system is electronically controlled.
Corolla
A parking lock cable is connected between shift lever and ignition lock assembly for control of key lock system. (Scheme 229)
All Others
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.
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 the lock mechanism.

Camry, Cressida, Land Cruiser, Pickup, Supra & 4Runner
Obtain access to ECU. See Figs. 3 to 11. Turn ignition on. Using voltmeter, check voltage between designated terminals on ECU with connector installed on ECU. Voltage should be as specified. (Scheme 238)
Note. Connector "A" goes to ignition switch, brakelight switch and key interlock solenoid. Connector "B" goes to shift lock solenoid. Connector "C" goes to shift lock control switch.
Celica, Corolla & MR2
- Obtain access to ECU. see scheme 2 Turn ignition on. Using voltmeter, check voltage between designated terminals on ECU with connector installed on ECU. Voltage should be as specified. (Scheme 242)or 19.
- Turn ignition off. Using ohmmeter, check for continuity between specified terminals. Continuity should be as specified. (Scheme 242)or 19.
Note. On Celica and MR2, connector "A" goes to ignition switch, brakelight switch and key interlock solenoid. Connector "B" goes to shift lock solenoid. Connector "C" goes to shift lock control switch.
Note. On Corolla, connector "A" goes to shift lock solenoid. Connector "B" goes to ignition switch and brakelight switch. Connector "C" goes to shift lock control switch.
Paseo & Tercel
Obtain access to ECU. (Scheme 229) Turn ignition on. Using voltmeter, check voltage between designated terminals on ECU with connector installed on ECU. Voltage should be as specified. (Scheme 247)
Note. Connector "A" goes to ignition switch, brakelight switch and key interlock solenoid. Connector "B" goes to shift lock solenoid and shift lock control switch.

SHIFT LOCK SOLENOID
- Disconnect electrical connector from shift lock solenoid. (Scheme 229) Using ohmmeter, measure resistance between electrical terminals of shift lock solenoid.
- Replace shift lock solenoid if resistance is not within limits. See «SHIFT LOCK SOLENOID RESISTANCE SPECIFICATIONS»(ref-56893-S11249856072001102200000) table.
- Apply battery voltage between electrical terminals of shift lock solenoid. Replace shift lock solenoid if operating sound cannot be heard.

SHIFT LOCK CONTROL SWITCH
Note. Land Cruiser testing not available at time of publication.
- Disconnect electrical connector from shift lock control switch. (Scheme 229) Note electrical connector terminal identification. (Scheme 251)
- Using ohmmeter, check continuity of terminals in relation to shift lever. See «SHIFT LOCK CONTROL SWITCH CONTINUITY»(ref-56893-S02894890222001102200000) table. Replace switch if continuity is not as specified.
Note. Continuity must be checked in accordance with position of release button on shift lever and shift lever position.
