REMOTE KEYLESS ENTRY SYSTEM
When the key switch is ON (key is inserted in ignition key cylinder), power is supplied
• through 10A fuse [No. 14, located in the fuse block (J/B)]
• through key switch terminals 2 and 1
• to BCM terminal 37.
When the ignition switch is ACC or ON, power is supplied
• through 10A fuse [No. 20, located in the fuse block (J/B)]
• to BCM terminal 11.
Ground is supplied
• to BCM terminal 67
• through body grounds M57 and M61.
When the front door switch LH is ON (door is OPEN), ground is supplied
• to BCM terminal 47
• through front door switch LH terminal 2
• through front door switch LH case ground.
When the front door switch RH is ON (door is OPEN), ground is supplied
• to BCM terminal 12
• through front door switch RH terminal 2
• through front door switch RH case ground.
When the rear door switch LH is ON (door is OPEN), ground is supplied
• to BCM terminal 48
• through rear door switch LH terminal 1
• through rear door switch LH case ground.
When the rear door switch RH is ON (door is OPEN), ground is supplied
• to BCM meter terminal 13
• through rear door switch RH terminal 1
• through rear door switch RH case ground.
When the back door lock assembly (back door switch) (hatchback) is ON (back door is OPEN), ground is sup-
plied
• to BCM terminal 43
• through back door lock assembly (back door switch) terminals 3 and 4
• through body grounds B117, B132 and D402.
Keyfob signal is inputted to BCM from remote keyless entry receiver.
The remote keyless entry system controls operation of the
• power door lock
• hazard reminder
• auto door lock
• panic alarm
• room lamp
OPERATED PROCEDURE
Power Door Lock Operation
BCM receives a LOCK signal from keyfob. BCM locks all doors with input of LOCK signal from keyfob.
BCM receives a UNLOCK signal from keyfob. BCM unlocks all doors with input of UNLOCK signal from key-
fob.
Hazard and Horn Reminder
When the doors are locked or unlocked by keyfob, power is supplied to sound horns and flash hazard warning
lamps as follows
• LOCK operation: 3 or 4 mode (lamps flash twice)
• UNLOCK operation: 2 or 4 mode (lamps flash once)
• Horns sound once with LOCK function when this feature is set ON.
The hazard reminder has modes 1, 2, 3 or 4. The horn reminder can be turned ON/OFF with any LOCK mode.
Operating function of hazard reminder
Hazard and horn reminders do not operate if any door switch is ON (any door is OPEN).
