General Bulb Failure Indicator (Active Low)

1. Check all monitored bulbs are operating correctly and have clean contacts.
2. When bulb failure lamp is illuminated and direction indicator tell tales flash at double the normal rate suspect a fault in the direction indicator circuitry or bulbs.
3. Check all lighting modules (LH front, RH front and rear) are correctly connected. Check harness continuity from modules to Body Processor Unit (BPU).
4. If indicator tell tales do not flash at double normal rate check wiring harness continuity between pin 43 (48-way connector) and Logic Control Module (LCM) harness connections 8 (LH and RH side) and 6 (rear).
