Light Warning Chime

WARNING: This page is about a different car, the 2003 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

With the key removed from the ignition switch, the driver's door open, and the lighting switch in 1st or 2nd position, the warning chime will sound. [Except when headlamp battery saver control operates (for 5 minutes after ignition switch is turned to OFF or ACC position) and headlamps do not illuminate.]

Signal is supplied

from combination switch (lighting switch) terminals 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10
to BCM terminals 40, 41, 42, 43, 47, 48, 49, 50, 51 and 52.

NOTE: BCM detected lighting switch in 1st or 2nd position, refer to COMBINATION SWITCH READING FUNCTION .

Ground is supplied

to unified meter and A/C amp. terminal 8
through driver side door switch terminal 4.

Driver side door switch is case grounded.

Unified meter and A/C amp. send door open signal to BCM with CAN communication line.

BCM detects headlamps are illuminated, and sends light warning signal to unified meter and A/C amp. with CAN communication line. Unified meter and A/C amp. sends light warning signal to combination meter with communication line between unified meter and A/C amp. and combination meter.

When combination meter receives light warning signal, it sounds warning chime.
