SYSTEM OUTLINE
WHEN THE IGNITION SW IS TURNED TO ACC POSITION THE CURRENT FROM THE CIG FUSE FLOWS TO TERMINAL
5 OF THE SHIFT LOCK ECU, IN THE ON POSITION, THE CURRENT FROM THE ECU-IG FUSE FLOWS TO TERMINAL 1
OF THE ECU.
1. SHIFT LOCK MECHANISM
WITH THE IGNITION SW ON, WHEN A SIGNAL THAT THE BRAKE PEDAL IS DEPRESSED (STOP LIGHT SW ON) AND A
SIGNAL THAT THE SHIFT LEVER IS PUT IN "P" POSITION (CONTINUITY BETWEEN P1 AND P OF THE SHIFT LOCK
CONTROL SW) IS INPUT TO THE ECU, THE ECU OPERATES AND CURRENT FLOWS FROM TERMINAL 1 OF THE ECU
TERMINAL 'SLS+' OF THE SHIFT LOCK SOLENOID SOLENOID
GROUND. THIS CAUSES THE SHIFT LOCK SOLENOID TO TURN ON (PLATE STOPPER DISENGAGES) AND THE
SHIFT LEVER CAN SHIFT INTO POSITION OTHER THAN THE "P".
2. KEY INTERLOCK MECHANISM
WITH THE IGNITION SW ON OR ACC POSITION, WHEN THE SHIFT LEVER IS PUT IN "P" POSITION (NO CONTINUITY
BETWEEN P2 AND P OF SHIFT LOCK CONTROL SW), THE CURRENT FLOWING FROM TERMINAL 6 OF THE ECU
KEY INTERLOCK SOLENOID IS CUT OFF. THIS CAUSES THE KEY INTERLOCK SOLENOID TO TURN OFF (LOCK
LEVER DISENGAGES FROM LOCK POSITION) AND THE IGNITION KEY CAN BE TURNED FROM ACC TO LOCK
POSITION.
