Light Warning Chime

WARNING: This page is about a different car, the 2005 Nissan 350Z. 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 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 ".

through driver side door switch terminal 1.

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.
