Control Of Unlocking Operation
2012 Mitsubishi RVR ESSECTION Control Of Unlocking Operation
- KOS-ECU detects the lock/unlock switch ON signal of door outside handle (driver's side, front passenger's side) or the liftgate lock release handle (open switch) ON signal.NOTE: When KOS-ECU detects the lock/unlock switch ON signal of door outside handle (driver's side, front passenger's side) or the liftgate lock release handle (open switch) ON signal, KOS-ECU judges the unlock prohibition condition. When the unlock prohibition condition is met, the unlocking operation is terminated.
- When KOS-ECU detects the lock/unlock switch ON signal of door outside handle (driver's side, front passenger's side) or the liftgate lock release handle (open switch) ON signal, KOS-ECU transmits the exterior data from the outside transmission antenna assembly on the operation side. At the same time, KOS-ECU transmits the interfering radio wave* (reversal code) from the outside transmission antenna assembly on the other side. (The interfering radio wave will be transmitted from the front passenger-side antenna assembly when the driver-side door outside handle is operated, and vice versa. It will not be transmitted when the liftgate lock release handle is operated.)NOTE: *: The interfering radio wave is transmitted to disable the door locking/unlocking operation performed by a person without the keyless operation key while a user with the keyless operation key is operating from the opposite side of the vehicle.
- After the exterior data are transmitted from the outside transmission antenna assembly, the interior data are transmitted from the inside transmission antenna assembly (front, rear).
- For the specified time (varies with the number of keyless operation keys registered in KOS-ECU), the response from the keyless operation key meeting the unlock condition is monitored.
- When the registered keyless operation key receives the exterior data only, KOS-ECU transmits the unlock request (request to unlock the applicable position) to ETACS-ECU.
- Even after the specified time has elapsed, if KOS-ECU receives no response that satisfies the unlock, it performs a retry once. (When no response after the retry, KOS-ECU terminates the unlocking operation.)
- When the unlocking operation is performed on the driver's side, the priority order of keyless operation key is updated.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
