Active Check Function

Operation Description

When a door is locked or unlocked by keyfob operation, the vehicle turn signals flash and the horn sounds to verify operation.

• When a button on the keyfob is operated, the signal is sent from the remote controller and received by the keyless remote entry receiver.
• The received signal is sent to the BCM and compared with the registered ID number.
• If the ID number matches, the BCM sends the turn signal flashing and horn signal to the IPDM E/R.
• The IPDM E/R flashes the turn signal lamps and sounds the horn for each keyfob operation.
