OPERATED PROCEDURE
Power Door Lock Operation

BCM locks all doors with receiving LOCK signal from key fob.
When an UNLOCK signal is sent from key fob once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from key fob again within 5 seconds, all other door will be unlocked.

Hazard and Horn Reminder

Power is supplied at all times

●

to horn relay terminal 2

●

through 10A fuse (No. 32, located in the fuse and fusible link box).

When BCM receives LOCK or UNLOCK signal from key fob with all doors closed, BCM sends horn chirp sig-
nal to IPDM E/R.
IPDM E/R grounds horn relay

●

to horn relay terminal 1

●

through IPDM E/R terminal 51, and

●

to BCM terminals 45 and 46 from hazard warning lamp system

Horn relay is now energized, and hazard warning lamp flashes and horn sounds as a reminder.
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

How to change hazard and horn reminder mode

With CONSULT-II

Hazard and horn reminder can be changed using “MULTI ANSWER BACK SET” mode in “WORK SUPPORT”.
Refer to

BL-70, "Work Support"

Without CONSULT-II

When LOCK and UNLOCK signals are sent from the key fob for more than 2 seconds at the same time, the
hazard and horn reminder mode is changed and hazard warning lamp flashes and horn sounds as follows:

Auto Door Lock Operation

Auto lock function signal is sent for operation when any of the following signals are not sent within 1 minute
after the unlock signal is sent from the key fob:

●

when door switch is turned ON for open.

●

When key switch is OFF (when ignition key is not inserted in ignition key cylinder), BCM turns on and off horn
and headlamp intermittently with input of PANIC ALARM signal from key fob.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from key fob.
Panic alarm operation mode can be changed using “PANIC ALARM SET” mode in “WORK SUPPORT”.
Refer to

BL-70, "Work Support"

For detailed description, refer to
