1. In case of Door KEY LOCK (Unlock) signal of driver's seat, handle as KEY LOCK (Unlock) of driver's seat is inputted if the knob in the driver's seat is LOCKED (Unlocked) after checking it for 3s.
2. In case of Door KEY LOCK (Unlock) signal of the passenger seat, handle as KEY LOCK (Unlock) of the passenger seat is inputted if the knob in the passenger seat is LOCKED (Unlocked) after checking it for 3s.

1. If Driver Door Key Lock SW or Passenger Door Key Lock SW turns ON, turn Door Lock Relay output ON during T1. But prohibit the output when KEY IN ON *2) and IGN1 are ON.
2. When Driver Door Key Unlock and Passenger Door Key Unlock turn ON, turn Door Unlock Relay and Driver Door Unlock Relay output ON during T1.
3. Turn CENTRAL LOCK *3) ON during T1 when receiving TX LOCK signal.

But ignore LOCK input when Driver Door SW or Passenger Door SW is ON.

4. Turn CENTRAL Unlock *4) ON during T1 when receiving TX Unlock signal.
5. Turn Door Lock Relay output ON during T1 when Power window Door Lock SW turns ON.
6. Turn CENTRAL Unlock output ON during T1 when Power window Door Unlock SW turns ON. But prohibit the operation by Power window Door Unlock SW at the condition of ARM, ARMWAIT, Rearm and Alarm.
7. LOCK/Unlock by Safety KNOB is not interlock (Mechanical operation).
8. Malfunction should be free when joining BATTERY (Also malfunction should be free at the location of Key In SW ON).
9. Input which is less than 60 msec should not be received (KEY LOCK/Unlock SW).
10. Do not execute the output of Door Lock (Unlock) by KNOB change.

*2) KEY IN ON : Key In ON

*3) CENTRAL LOCK : Refer to control mode for each Spec.

*4) CENTRAL LOCK : Refer to control mode for each Spec.

T1 : 0.5 ± 0.1 sec

1. If Driver Door Key Unlock SW turns OFF from ON within T1 after Driver Door Key Unlock SW turns ON from OFF (Driver Door Unlock SW becomes Unlocked mechanically and does not output BCM.), turn Door Unlock Relay output ON during T2.
2. If TX Unlock is received within T1 after Driver Door Key Unlock SW turns ON from OFF (Driver Door Unlock SW becomes Unlocked mechanically and does not output BCM.), turn Driver Door Unlock Relay and Door Unlock Relay output ON during T2.
3. Turn Driver Door Unlock Relay output ON during T2 when receiving TX Unlock signal. However, turn Driver Door Unlock Relay and Door Unlock Relay output during T2 if TX Unlock is received within T1.
4. Also, turn Driver Door Unlock Relay and Door Unlock Relay ON during T2 in case that Driver Door Key Unlock SW turns ON from OFF within T1 after receiving TX Unlock.
5. Regard as the same TX even though different signal which is registered within T1 is received.

T1: 4 ± 1 sec, T2 : 0.5 ± 0.1 sec

1. This function will not be operated if the speed of cars exceed 3 km/h.
2. Perform DR Unlock Relay output for 1s after 0.5s when the condition becomes to be KEY IN ON & DRV DR SW OPEN & DRV DR Unlock SW LOCK.
3. Perform DRV Unlock Relay output for 1s after 0.5s when the condition becomes to be KEY IN ON & DRV DR SW OPEN & DRV DR Unlock SW LOCK.
4. Perform DR Unlock Relay output for 1s in 0.5s when the condition becomes to be KEY IN ON & AST DR SW OPEN & AST DR Unlock SW LOCK.
5. Output CENTRAL UNLOCK for 1s in 0.5s based on (4) if (2) and (4) are satisfied.
6. Output UNLOCK up to 3 times (excluding output for 1s) if LOCK condition is maintained though UNLOCK output is performed for 1s by (2), (3) (cycle for 1s: 0.5s ON/OFF).
7. Try unlocking once when DOOR is CLOSED while keeping LOCK condition after performing (5) and (6).
8. Output DR Unlock Relay once for 1s when DRV DR SW is closed within 0.5s since DRV DR Unlock SW is changed from UNLOCK to LOCK during KEY IN ON.
9. Output DRV Unlock Relay once only for 1s when DRV DR SW is closed within 0.5s since DRV DR Unlock SW is changed from UNLOCK to LOCK during KEY IN ON.
10. Output CENTRAL UNLOCK once only for 1s when AST DR SW is closed within 0.5s since AST DR Unlock SW is changed from UNLOCK to LOCK during KEY IN ON.
11. Output DR Unlock Relay once only for 1s if DRV DR Unlock SW becomes LOCK from UNLOCK within 0.5s since DRV DR SW is changed from OPEN to CLOSE during KEY IN ON
12. Output DRV Unlock Relay for 1s when DRV DR Unlock SW becomes LOCK from UNLOCK within 0.5s since DRV DR SW is changed from OPEN to CLOSE during KEY IN ON
13. Output CENTRAL UNLOCK once only for 1s if AST DR Unlock SW becomes to be LOCK from UNLOCK within 0.5s since AST DR SW is changed from OPEN to CLOSE during KEY IN ON.
14. Perform the function of KEY REMINDER when turning Power window DR Lock SW ON after opening DRV DR SW or AST DR SW during KEY IN ON.
15. Judge if RETRY output is performed or not at the point of the beginning of RETRY output (in 1.5s from the initial UNLOCK output).
16. Output UNLOCK though the condition is not kept for 0.5 sec after realizing that of UNLOCK. But, do not output UNLOCK in case that KEY IN is OFF at the point of 0.5s passed after realizing the condition by the change of UNLOCK → LOCK in DRV DR Unlock SW or AST DR Unlock SW.

T1, T3 : 0.5 ± 0.1 sec, T2 : 1 ± 0.1 sec, T4 : 0.5 sec Max

**KEY IN ON : Key In ON or IGN1 ON or IGN2 ON

KEY IN OFF: Key In OFF and IGN1 OFF and IGN2 OFF

1. Always perform CENTRAL Unlock *9) output whenever Crash Input signal is inputted while IGN1 is ON.
2. Keep CENTRAL Unlock output for the time left though IGN1 turns OFF from ON while outputting CENTRAL Unlock.
3. Do not output CENTRAL Unlock if IGN1 SW turns ON from OFF after Crash Input signal is already inputted.
4. Output CENTRAL Unlock during T3 if Driver Door Unlock SW or Passenger Door Unlock SW or Rear Right Door Unlock SW or Rear Left Door Unlock SW turns to LOCK from Unlock after outputting CENTRAL Unlock.
5. Do not perform AUTO Door Lock function at the condition of CRASH Unlock.
6. CRASH Door Unlock function has priority to LOCK/Unlock control by other functions.
7. Ignore the request for LOCK/Unlock by other functions while or after outputting CRASH Door Unlock. But, control LOCK/Unlock by other functions if IGN1 SW becomes OFF.

T1 : 0.2 sec, T2 : 40 msec,

T3 : 5 ± 0.5 sec

1. AUTO Door Lock is classified into non-activation/20 km actiovation/40 km activation. And follow the table below for the basic value and selected value of the regional operation SPEC.

   Item	Description
   Standard	Disable
   Option 1	20 km/h

2. On condition of IGN1 SW ON, turn Door Lock Relay output ON within T1 when keeping more than setting speed in (1). But, do not output LOCK if all Doors are LOCKED or FAIL at first.
3. Perform outputting LOCK up to 3 times (cycle for 1s) if either of Doors is Unlocked after outputting LOCK in (2). But, ignore the Door that has changed to LOCK condition from Unlock during the output 3 times.
4. Regard the respective Door FAILED if it is Unlocked after outputting 3 times.
5. Output LOCK once only if the Door is Unlocked after the failed Door changes (Unlock LOCK).
6. Output LOCK once only if Door which was LOCKED after outputting LOCK in (2) becomes to be Unlocked.

But, output LOCK once for the respective Door although it keeps Unlock after LOCK output.

7. Clear the FAILED Door when L_IGN1 SW is OFF.
8. Do not perform AUTO Door Lock function on condition of CRASH Unlock.

*1 ON (Unlock) : Driver DR Unlock SW | Passenger DR Unlock SW | Rear Right DR Unlock SW | Rear Left DR Unlock SW UNLOCK

OFF (LOCK) : Driver DR Unlock SW | Passenger DR Unlock SW | Rear Right DR Unlock SW | Rear Left DR Unlock SW LOCK

1. AUTO Door Unlock is classified into non-activation and activation and activated for domestic ones only but not activated for others.
2. If it is set up to be activated, turn DR Unlock relay ON when turning KEY IN OFF after KEY IN is ON.

   [(But, if all conditions for KNOB are Unlock, it will not output.) AUTO Door Unlock should operate after outputting AUTO Door Lock (Unlock OUTPUT will not occur though the key is removed later if LOCK OUTPUT did not occur because all KNOBS are already LOCKED even though it reached to the operating speed of AUTO Door Lock.)]
