System Description

OUTLINE
Power is supplied at all times
- through 50 A fusible link (letter g, located in the fuse and fusible link box)
- to BCM (body control module) terminal 70, and
- through 10 A fuse [No. 19, located in the fuse block (J/B)]
- to combination meter terminal 3.

HAZARD LAMP OPERATION
Power is supplied at all times
- through 50 A fusible link (letter g, located in the fuse and fusible link box)
- to BCM terminal 70, and
- through 10 A fuse [No. 19, located in the fuse block (J/B)]
- to combination meter terminal 3.

Ground is supplied
- to BCM terminal 67 and
- to combination meter terminal 13
- through grounds M57, M61 and M79.

When the hazard switch is depressed, ground is supplied
- to BCM terminal 29
- through hazard switch terminal 2
- through hazard switch terminal 1
- through grounds M57, M61 and M79.

When the hazard switch is depressed, the BCM, interpreting it as turn signal is ON, outputs turn signal from BCM terminals 60 and 61.

The BCM supplies power
- through BCM terminals 60 and 61
- to front combination lamp LH and RH (turn signal) terminal 6
- through front combination lamp LH and RH (turn signal) terminal 5, and
- to rear combination lamp LH and RH (turn signal) terminal 4
- through rear combination lamp LH and RH (turn signal) terminal 5
- to grounds E9, E15 (all) and E24 (VQ40DE engine only).

BCM sends signal to combination meter through CAN communication lines and turns on turn signal indicator lamps within combination meter.
