Light Warning Chime

WARNING: This page is about a different car, the 2004 Nissan Maxima. 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 (part of the combination switch) in 1st or 2nd position, the warning chime will sound. [This is the operation of the light warning chime, 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 2, 3, 4, 5, 6, 32, 33, 34, 35 and 36.

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

Ground is supplied

to BCM terminal 62
through front door switch LH terminal 2.

Front door switch LH is case grounded.

BCM sends door open signal to unified meter and A/C amp. via CAN communication lines.

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

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