OPERATION PROCEDURE
BCM can not receive signals (except keyless power window down signal) from keyfob when key switch is ON.

Power Door Lock Operation
BCM receives a LOCK signal from keyfob. BCM locks all doors with input of LOCK signal from keyfob.

When an UNLOCK signal is sent from keyfob once, driver's door is unlocked.

Then, if an UNLOCK signal is sent from keyfob again within 5 seconds, passenger door is unlocked.

Hazard and Horn Reminder
When the doors are locked or unlocked by keyfob, power is supplied to hazard warning lamp flashes as follows
- LOCK operation: C mode (flash twice) or S mode (flash twice)
- UNLOCK operation: C mode (flash once) or S mode (does not flash)

BCM outputs to IPDM E/R for horn reminder signal through DATA LINE (CAN H line and CAN L line).

The hazard and horn reminder has C mode (horn chirp mode) and S mode (non-horn chirp mode).




Operating function of hazard and horn reminder
Hazard and horn reminder does not operate if any of door switches is ON (any of doors is OPEN)
