SYSTEM OUTLINE
CURRENT ALWAYS FLOWS TO TERMINAL QDa OF THE THEFT DETERRENT ECU (W/ THEFT DETERRENT SYSTEM) OR TERMINAL a OF THE DOOR
LOCK CONTROL RELAY (W/O THEFT DETERRENT SYSTEM) THROUGH THE DOOR FUSE.


  1. LOCK OPERATION
    TO CHANGE DOOR LOCK SW AND KEY SII TO LOCK POSITION. A LOCK SIGNAL IS INPUT TO TERMINAL QDU.##BI7 OF THE THEFT
    DETERRENT ECU (W/ THEFT DETERRENT SYSTEM) OR TERMINAL 10 OF THE DOOR CONTROL RELAY (W/O THEFT DETERRENT SYSTEM) AND
    CAUSES THE RELAY TO FUNCTION. CURRENT FLOWS FROM TERMINAL QDa OF THE ECU (W/ THEFT DETERRENT SYSTEM) OR TERMINAL a OF
    THE RELAY (W/O THEFT DETERRENT SYSTEM) ~ TERMI.lL QD4 OF THE ECU (W/ THEFT DETERRENT SYSTEM) OR TERMINAL 4 OF THE
    RELAY (W/O THEFT DETERRENT SYSTEM) ~ TERMINAL 4' (FRONT DOOR). 6 (BACK DOOR). 4 (SLIDE DOOR. W/ THEFT DETERRENT
    SYSTEM) OR 1 (SLIDE 11/0 THEFT DETERRENT SYSTEM) OF THE DOOR LOCK MOTORS ~ TERMINAL 2 (FRONT DOOR). 3 (BACK DOOR).
    2 (SLIDE DOOR. W/ THEFT DETERRENT SYSTEMI OR 3 (SLIDE DOOR. W/O THEFT DETERRENT SYSTEM) ~ TERMINAL QD3 OF THE ECU
    (W/ THEFT DETERRENT SYSTEM) OR TERMINAL 3 OF THE RELAY (W/O THEFT DETERRENT SYSTEM 1 ~ TERMINAL QD16 (W/ THEFT
    DETERRENT SYSTEM) OR TERMINAL 16 (W/O THEFT DETERRENT SYSTEM) ~ TO GROUND AND DOOR LOCK MOTOR CAUSES TO LOCK.

  2. UNLOCK OPERATION
    TO CHANGE DOOR LOCK CONTROL SW AND KEY SW TO UNLOCK POS IT I ON. AN UNLOCK SI GNAL IS. INPUT TO TERMINAL QD 1 O. QD 111. QD
    18 OF THE THEFT DETERRENT ECU (W/ THEFT DETERRENT SYSTEM 1 OR TERM,INAL 11. 9 OF THE DOOR CONTROL RELAY (11/0 THEFT
    DETERRENT SYSTEM 1 AND CAUSES THE RELAY TO FUNCTI ON. CURRENT FLOWS FROM TERMINAL QD a OF THE ECU (W/ THEFT DETERRENT
    SYSTEM 1 OR TERMINAL a OF THE RELAY (W/O THEFT DETERR-ENT SYSTEM) ~ TERMINAL QD3 OF THE ECU (W/ THEFT DETERRENT
    SYSTEM 1 OR TERMINAL 3 OF THE RELAY DOOR (W/O THEFT DETERRENT SYSTEM) ~ TERMINAL 2 (FRONT DOOR I. 3 (BACK DOOR).
    2(SLIDE DOOR. W/ THEFT DETERRENT SYSTEM) OR 3 (SLIDE DOOR. W/O THEFT DETERRENT SYSTEM) OF THE DOOR LOCK MOTORS ~
    TERMINAL 4 (FRONT DOORI. 6 (BACK DOOR) 4 (SLIDE DOOR. W/ THEFT DETERRENT SYSTEM 1 OR 1 (SLIDE DOOR 11/0 THEFT DETERRENT
    SYSTEM 1 ~ TERMINAL QD4 OF THE ECU (WI THEFT DETERRENT SYSTEM) OR TERMINAL 4 OF THE RELAY (w/o THEFT DETERRENT
    SYSTEM 1 ~ TERMINAL QD 16 (W/ THEFT DETERRENT SYSTEM) OR TERMINAL 16 (W/O THEFT DETERRENT SYSTEM) ~ TO GROUND AND
    DOOR LOCK MOTOR CAUSES TO UNLOCK.

  3. DOUBLE OPERATION UNLOCK OPERATION
    WHEN THE DOOR LOCK KEY sw (DRIVER'S) IS TURNED TO THE UNLOCK SIDE. ONLY THE DRIVER'S DOOR IS MACHANICALLY UNLOCKED.
    TURNING THE DOOR LOCK KEY sw (DRIVER'S) TO THE UNLOCK SIDE CAUSES A SIGNAL TO BE INPUT TO TERMINAL QDl0 OF THE THEFT
    DETERRENT ECU (W/ THEFT DETERRENT SYSTEM) OR TERMINAL 9 OF THE DOOR LOCK CONTROL RELAY (W/O THEFT DETERRENT SYSTEM).
    AND IF THE INPUT SIGNAL AGAIN WITHIN 3 SECONDS BY THE SWITCH TO THE UNLOCK SIDE AGAIN. CURRENT FLOWS ~ROM TERMINAL
