WHEN THE IGNITION SW IS TURNED TO ACC POSITION THE CURRENT FROM THE CIG & RAD 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 Pº 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 " TERMINAL SLS- "TERMINAL 4 OF THE ECU "GROUND. THIS CAUSES THE SHIFT LOCK SOLENOID
TO TURN ON (PLATE STOPPER DISENGAGES) AND THE SHIFT LEVER CAN SHIFT INTO POSITION OTHER THAN THE Pº.
2. KEY INTERLOCK MECHANISM
WITH THE IGNITION SW ON OR ACC POSITION, WHEN THE SHIFT LEVER IS PUT IN Pº POSITION (NO CONTINUITY BETWEEN P2
AND P OF SHIFT LOCK CONTROL SW), THE CURRENT FLOWING FROM TERMINAL 6 OF THE ECU "THE 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.
