Door Locks (Keyless Transmitter Operation)

The doors can be locked and unlocked with the Keyless Transmitter. All lock and unlock commands are received by the Immobilizer-Keyless Control Unit. The Immobilizer-Keyless Control Unit communicates the lock and unlock commands to the Driver's MICU and Passenger's MICU via B-CAN.

According to the switch request, the Driver's MICU and Passenger's MICU control a series of relays which provide power and ground to the reversible electric door lock motors for lock and unlock modes.

Pressing the UNLOCK button one time will command the Driver's MICU to unlock the driver's door. Pressing the unlock button a second time will command the Driver's MICU and Passenger's MICU to unlock the remaining doors.

Pressing the LOCK button will command the Driver's MICU and Passenger's MICU to lock all of the doors.
