Driver Door Unlock	OFF	ON	OFF

CENTRAL DOOR LOCK/UNLOCK
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 60msec 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: *3) CENTRAL LOCK: Refer to Control Mode for each Spec.

IGN KEY REMINDER
1. This function will not be operated if the speed of cars exceed 3km/h.
2. Perform Door Unlock Relay output for 1s after 0.5s when the condition becomes to be KEY IN ON, Driver Door SW is OPENED and Driver Door Unlock SW is LOCKED.
3. Perform ALL Door Unlock Relay output for 1s in 0.5s when the condition becomes to be KEY IN ON, Passenger Door SW is OPENED and Passenger Door Unlock SW is LOCKED.
4. Output ALL DOOR UNLOCK for 1s in 0.5s based on (3) if (2) and (3) are satisfied.
5. 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).
6. Try UNLOCK once when DOOR is CLOSED while keeping LOCK condition after performing (5).
7. Output Door Unlock Relay once for 1s when Driver Door SW is closed within 0.5s since Driver Door Unlock SW is changed from UNLOCK to LOCK during KEY IN ON.
8. Output ALL DOOR UNLOCK once only for 1s when Passenger Door SW is closed within 0.5s since Passenger Door Unlock SW is changed from UNLOCK to LOCK during KEY IN ON.
9. Output ALL Door Unlock Relay once only for 1s if Driver Door Unlock SW becomes LOCK from UNLOCK within 0.5s since Driver Door SW is changed from OPEN to CLOSE during KEY IN ON.
10. Perform the function of KEY REMINDER when turning Power window Door Lock SW ON after opening Driver Door SW or Passenger Door SW during KEY IN ON.
11. 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).
12. Output UNLOCK though the condition is not kept for 0.5sec 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 Driver Door Unlock SW or Passenger Door Unlock SW.

CRASH DOOR UNLOCK
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.

AUTO DOOR LOCK

AUTO DOOR LOCK is classified into non-activation/20km activation/40km activation. Follow the AUTO DOOR LOCK OPERATION SPEC CHART for the basic value and selected value of the regional operation SPEC.

AUTO DOOR LOCK OPERATION SPEC CHART

Item	Description
Standard	Disable
Option 1	20 km/h

On condition of IGN1 SW ON, output all door lock within T1 when keeping more than setting speed in (1). But, do not output LOCK if all DOORS are LOCKED or FAIL at first.
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.
Regard the respective DOOR FAILED if it is UNLOCKED after outputting 3 times.
Output LOCK once only if the DOOR is UNLOCKED after the failed DOOR changes (UNLOCK→LOCK).
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.
Clear the FAILED DOOR when L_IGN1 SW is OFF.
Do not perform AUTO DOOR LOCK function on condition of CRASH UNLOCK.

AUTO DOOR UNLOCK
1. AUTO DOOR UNLOCK is classified into non-activation and activation and activated for domestic ones only but not activated for others.
2. If any door is locked, output all door unlock when turning KEY IN OFF after KEY IN is ON. [ (But, if all door is UNLOCK, it will not output.) AUTO DOOR UNLOCK should operate regardless outputting auto door lock.)]
