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 terminals 13 and 23

When the hazard switch is depressed, ground is supplied
- to BCM terminal 29
- through hazard switch terminal 2
- through hazard switch terminal 1

When the hazard switch is depressed, the BCM, interpreting it as hazard warning lamps are 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 and
- to rear combination lamp LH and RH terminal 4.

Ground is supplied
- to front combination lamp LH and RH (turn signal) terminal 5
- through grounds E9, E15 and E24,
- to rear combination lamp LH terminal 5

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