B1602 ACURA Description
The remote is equipped with a keyless transmitter, and all doors can be locked and unlocked by a lock/unlock button operation, even from a remote distance from the vehicle. When the remote lock button or the remote unlock button is pressed, the keyless transmitter sends the applicable switch signal to the keyless access control unit. After receiving the authentication at the Keyless Access Control Unit, then the door lock signals are sent to MICU through B-CAN.
