DOOR LOCK
SYSTEM OUTLINE
CURRENT ALWAYS FLOWS TO TERMINAL 8 OF THE DOOR LOCK ECU THROUGH THE DOOR FUSE.
WITH THE IGNITION SW TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL 1 OF THE DOOR LOCK ECU
AND TERMINAL 1 OF DIODE
1. MANUAL LOCK OPERATION
TO CHANGE DOOR LOCK SW AND KEY SW TO LOCK POSITION, A LOCK SIGNAL IS INPUT TO TERMINALS 10, 12 OF THE DOOR
LOCK ECU AND CAUSES THE ECU TO FUNCTION. CURRENT FLOWS FROM TERMINAL 8 OF THE ECU
(A)5 (LH), (A)6 (RH) (W/ THEFT DETERRENT), (B)4 (W/O THEFT DETERRENT) OF THE DOOR LOCK MOTORS
(A)3 (RH) (W/ THEFT DETERRENT), (B)2 (W/O THEFT DETERRENT)
DOOR LOCK MOTORS CAUSES THE DOOR LOCK.
2. MANUAL UNLOCK OPERATION
TO CAHNGE DOOR LOCK CONTROL SW AND KEY SW TO UNLOCK POSITION, AN UNLOCK SIGNAL IS INPUT TO TERMINALS 11, 13
OF THE DOOR LOCK ECU, AND CAUSES THE ECU TO FUNCTION. CURRENT FLOWS FROM TERMINAL 8 OF THE ECU
TERMINAL (A)2 (LH), (A)3 (RH) (W/ THEFT DETERRENT), (B)2 (W/O THEFT DETERRENT) OF THE DOOR LOCK MOTORS
TERMINAL (A)5 (LH), (A)6 (RH) (W/ THEFT DETERRENT), (B)4 (W/O THEFT DETERRENT)
TO GROUND AND DOOR LOCK MOTORS CAUSES DOOR TO UNLOCK.
3. DUBLE OPERATION UNLOCK OPERATION
WHEN THE DOOR LOCK KEY SW (DRIVER'S) IS TURNED TO THE UNLOCK SIDE, ONLY THE DRIVER'S DOOR IS MECHANICALLY
UNLOCKED. TURNING THE DOOR LOCK KEY SW (DRIVER'S) TO THE UNLOCK SIDE CAUSES A SIGNAL TO BE INPUT TO TERMINAL 9
OF THE ECU, AND IF THE SIGNAL IS INPUT AGAIN WITHIN 3 SECONDS BY TURNING THE SWITCH TO THE UNLOCK SIDE AGAIN
CURRENT FLOWS FROM TERMINAL 3 OF THE ECU
DETERRENT) OF DOOR LOCK MOTORS
TERMINAL 4 OF THE ECU
PASSENGER'S DOOR.
4. IGNITION KEY REMINDER OPERATION
∗ OPERATING DOOR LOCK KNOB (IN DOOR LOCK MOTORS OPERATION)
WITH IGNITION KEY IN CYLINDER (UNLOCK WARNING SW ON), WHEN THE DOOR IS OPENED AND LOCKED USING DOOR LOCK
KNOB (DOOR LOCK MOTOR), THE DOOR IS LOCKED ONCE BUT EACH DOOR IS UNLOCKED SOON BY THE FUNCTION OF THE ECU.
AS A RESULT, THE CURRENT FLOWS FROM TERMINAL 8 OF THE ECU
DETERRENT), (B)2 (W/O THEFT DETERRENT) OF THE DOOR LOCK MOTORS
DETERRENT), (B)4 (W/O THEFT DETERRENT)
DOORS TO UNLOCK.
∗ OPERATING DOOR LOCK CONTROL SW OR DOOR LOCK KEY SW
WITH IGNITION KEY IN CYLINDER (UNLOCK WARNING SW ON), WHEN THE DOOR IS OPENED AND LOCKED USING DOOR LOCK
CONTROL SW OR KEY SW, THE DOOR IS LOCKED ONCE BUT EACH DOOR IS UNLOCK BY THE FUNCTION OF SW CONTAINED IN
MOTORS, WHICH THE SIGNAL IS INPUT TO TERMINAL 6 (DRIVER'S) OR 5 (PASSENGER'S) OF THE ECU. ACCORDING TO THIS INPUT
SIGNAL, THE CURRENT IN THE ECU FLOWS FROM TERMINAL 8 OF THE ECU
THEFT DETERRENT), (B)2 (W/O THEFT DETERRENT) OF THE DOOR LOCK MOTORS
DETERRENT), (B)4 (W/O THEFT DETERRENT)
DOORS TO UNLOCK.
∗ IN CASE OF KEY LESS LOCK
WITH IGNITION KEY IN CYLINDER (UNLOCK WARNING SW ON), WHEN THE UNLOCK FUNCTION IS DISTURBED MORE THAN 0.2
SECONDS, FOR EXAMPLE PUSHING THE DOOR LOCK KNOB ETC., THE DOOR HOLDS ON LOCK CONDITION. CLOSING THE DOOR
AFTER, DOOR COURTESY SW INPUTS THE SIGNAL INTO TERMINAL 2 OR 14 OF THE ECU. BY THIS INPUTS SIGNAL, THE ECU
WORKS AND CURRENT FLOWS FROM TERMINAL 8 OF THE ECU
DETERRENT), (B)2 (W/O THEFT DETERRENT) OF THE DOOR LOCK MOTORS
DETERRENT), (B)4 (W/O THEFT DETERRENT)
DOORS TO UNLOCK.
