Hazard Lamp Operation

Power is supplied at all times

To BCM (body control module) terminal 7
Through 40A fusible link [letter F, located in the fuse and fusible link box], and
To combination meter terminal 24
Through 10A fuse [No. 19, located in the fuse block (J/B)]
Ground is supplied
To hazard switch terminal 2
Through grounds M30 and M66
To BCM terminals 8,
Through grounds E17, E43 and F152
To combination meter terminals 10,11 and 12
Through grounds M30 and M66
When the hazard switch is depressed, ground is supplied
To BCM terminal 61
Through hazard lamp switch terminal 1.
The BCM then supplies power
Through BCM terminal 22
To front turn signal lamp LH (part of the front combination lamp LH) terminal 2 (with xenon headlamp)
To front turn signal lamp LH (part of the front combination lamp LH) terminal 1 (with halogen headlamp)
To rear turn signal lamp LH (part of the rear combination lamp LH) terminal 2
Through BCM terminal 21
To front turn signal lamp RH (part of the front combination lamp RH) terminal 2 (with xenon headlamp)
To front turn signal lamp RH (part of the rear combination lamp RH) terminal 1 (with halogen headlamp
To rear turn signal lamp RH (part of the rear combination lamp RH) terminal 2.
Ground is supplied
To the front turn signal lamp LH (part of the front combination lamp LH) terminal 1 through grounds E17, E43 and F152 (with xenon headlamp)
To the front turn signal lamp LH (part of the front combination lamp LH) terminal 4 through grounds E17, E43 and F152 (with halogen headlamp)
To the front turn signal lamp RH (part of the front combination lamp RH) terminal 1 through grounds E17, E43 and F152 (with xenon headlamp)
To the front turn signal lamp RH (part of the front combination lamp RH) terminal 4 through grounds E17, E43 and F152 (with halogen headlamp)
To the front turn signal lamp RH (part of the front combination lamp LH) terminal 4 through grounds T14, B6, B5andD105.
To the front turn signal lamp RH (part of the front combination lamp RH) terminal 4 through grounds T14, B6, B5and D105.

The BCM also supplies input to combination meter terminals 1 and 11 across the CAN communication lines.

This input is processed by the unified meter control unit in the combination meter through the unified meter and A/C amp, which in turn supplies ground to the left and right turn signal indicator lamps.

With power and ground supplied, the BCM controls the flashing of the hazard warning lamps.
