Door Lock Remote Keyless Entry

When the LOCK button is pressed on the transmitter and the keyless entry module receives a signal with a valid Vehicle Access Code (VAC), the lock function sequence is performed. The keyless entry module will lock all doors.

The keyless entry module supplies battery voltage from connector C2 terminal "D" to the coil of the lock relay (part of the door lock relay assembly) through the CKT 195 wire. See WIRING DIAGRAMS  . The lock relay is energized, and battery voltage is supplied to the door lock motors. Ground for the left door lock motor is provided at the keyless entry module connector C1 terminal "D" through internal contacts. Ground for the other door lock motors are provided through the contacts of the UNLOCK switch, inside the door lock relay assembly. All door lock motors run to lock all doors.

The unlock function is separated into 2 operations depending on how the UNLOCK button is pressed on the transmitter. If the UNLOCK button is pressed once, only the left door will unlock. If the UNLOCK button is pressed twice within 1-5 seconds, the other doors will unlock.

When the UNLOCK button is pressed once on the transmitter and the keyless entry module receives a valid VAC, the unlock function sequenced is performed. The keyless entry module supplies battery voltage to the left front door lock motor through the CKT 694 wire. See WIRING DIAGRAMS  . The motor is grounded through the contacts of the lock switch inside the door lock relay assembly. The left front door lock motor runs to unlock the left front door.

If the UNLOCK button on the transmitter is pressed twice to unlock all doors, the keyless entry module activates the door unlock output at connector C2 terminal "E". The keyless entry module supplies battery voltage to the coil of the unlock relay in the door lock relay assembly. The unlock relay is energized and closes its contacts. Battery voltage is supplied to the right front, left rear and right rear door lock motors. The motors are grounded through contacts of the lock switch, inside the door lock relay assembly. The motors run to unlock the right front, left rear, and right rear doors.
