3. Door Key Lock/unlock
(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.








4. Central Door Lock/unlock
(1) If Driver Door Key Lock Switch or Passenger Door Key Lock Switch turns ON, turn Door Lock Relay output ON during T1. But prohibit the output when KEY IN ON 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 *1) ON during T1 when receiving TLOCK signal.
But ignore LOCK input when Driver Door SW or Passenger Door SW is ON.
(4) Turn CENTRAL UNLOCK *2) ON during T1 when receiving TUNLOCK signal.
(5) LOCK/UNLOCK by SAFETY KNOB is not interlock (Mechanical operation).
(6) Malfunction should be free when joining BATTERY (Also malfunction should be free at the location of Key In Switch ON).
(7) Input which is less than 60msec should not be received (KEY LOCK/UNLOCK Switch).
(8) Do not execute the output of DOOR LOCK (UNLOCK) by KNOB change.
(9) If Power Window Lock Switch is ON, turn Lock Relay output ON for T1. (NORTH AMERICA)
(10) If Power window Lock Switch is ON, turn CENTRAL UNLOCK output ON for T1. (NORTH AMERICA) But, inhibit operating by Power window Unlock Switch at Lock state by TX.
*1) CENTRAL LOCK : Refer to control mode for each Spec.
*2) CENTRAL LOCK : Refer to control mode for each Spec.




T1 : 0.5 ± 0.1sec
5. 2-Turn Unlock
(1) If Driver Door Key Unlock Switch turns OFF from ON within T1 after Driver Door Key Unlock Switch turns ON from OFF(Driver Door Unlock Switch becomes UNLOCKED mechanically and does not output BCM.), turn Driver Unlock Relay, Unlock Relay(Central Unlock) output ON duting T2.
(2) If TUNLOCK is received within T1 after Driver Door Key Unlock Switch turns ON from OFF (Driver Door Unlock Switch becomes UNLOCKED mechanically and does not output BCM.), turn Driver Unlock Relay and Unlock Relay(Central Unlock) output ON during T2.
(3) Turn Driver Unlock Relay output ON during T2 when receiving TUNLOCK signal. However, turn Driver Unlock Relay, Unlock Relay (Central Unlock) output duting T2 if TUNLOCK is received within T1.
(4) Also, turn Driver Unlock Relay, Unlock Relay (Central Unlock) ON during T2 in case that Driver Door Key Unlock Switch turns ON from OFF within T1 after receiving TUNLOCK.
(5) Regard as the same TX even though different signal which is registered within T1 is received.
(6) If turn Lock Relay output ON by TLock or Driver/Assist Key lock Switch, T1 is initialized.
(7) Assist Key Unlock Switch turns ON from OFF, turn Driver Unlock Relay and Unlock Relay (Central Unlock) output ON during T2.








T1 : 4 ± 1sec, T2 : 0.5 ± 0.1sec
6. IGN Key Reminder
(1) This function will not be operated if the speed of cars exceeds 3km/h.
(2) Perform Unlock Relay output for 1s after 0.5s when the condition becomes to be KEY IN = ON& Driver Door open Switch = OPEN & Driver Door Unlock Switch = LOCK(Regions for North America).
(3) Perform Driver Unlock Relay output for 1s after 0.5s when the condition becomes to be KEY IN = ON & Driver Door open Switch = OPEN & Driver Door Unlock Switch = LOCK.(Spec for North America ONLY)
(4) Perform Unlock Relay output for 1s in 0.5s when the condition becomes to be KEY IN = ON & Assist Door Open Switch =OPEN & Assist Door Unlock Switch = LOCK.
(5) Output CENTRAL UNLOCK for 1s in 0.5s based on (4) if (1), (3) 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), (4)(cycle for 1s: 0.5s ON/OFF).
(7) Try UNLOCK once when DOOR is CLOSED while keeping LOCK condition after performing (6).
(8) Output Driver Unlock Relay once only for 1s when Driver Door open Switch is closed within 0.5s since Driver Door Unlock Switch is changed from UNLOCK to LOCK during KEY IN = ON(North America SPEC ONLY).
(9) Output CENTRAL UNLOCK once only for 1s when Assist Door Open Switch is closed within 0.5s since Assist Door Unlock Switch is changed from UNLOCK to LOCK during KEY IN = ON.

(12) 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).
(13) 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 Switch or Assist Door Unlock Switch.

7. Crash Door Unlock
(1) Always perform CENTRAL UNLOCK output whenever Crash Sensor signal is inputted(Duty 20%±10%) while IGN1 is ON. (But ignore Sensor input during 5sec output.)
(2) Judge Sensor Fail if Crash Sensor signal is more than T3, Crash Door Unlock is not operated.
(3) Keep CENTRAL UNLOCK output for the time left though IGN1 turns OFF from ON while outputting CENTRAL UNLOCK.
(4) Do not output CENTRAL UNLOCK if IGN1 switch turns ON from OFF after Crash Sensor signal is already inputted.
