System Description

System Description
When the ignition switch is in the ON or START position, power is supplied
- through 10 A fuse [No. 1, located in the fuse block (J/B)]
- to BCM (body control module) terminal 35, and
- through 10 A fuse [No.14, located in the fuse block (J/B)]
- to terminals 41 and 42 of the combination meter.

Ground is supplied
- to BCM (body control module) terminals 8
- through body grounds E17, and E43, and
- to combination meter terminals 45 and 46
- through body grounds M30 and M66.

LH Turn
When the turn signal switch (combination switch) is moved to the left position, the BCM (body control module) receives input requesting the left turn signals to flash. The BCM then supplies power
- through BCM (body control module) terminal 22
- to front turn signal lamp LH (part of the front combination lamp LH) terminal 6
- to rear turn signal lamp LH (part of the rear combination lamp LH) terminal 3.

Ground is supplied to the front turn signal lamp LH (part of the front combination lamp LH) terminal 4 through body grounds E17 and E43.

Ground is supplied to the rear turn signal lamp LH (part of the rear combination lamp) terminal 4 through body grounds B103.

The BCM also supplies ground to combination meter terminals 27 and 28 across the CAN communication lines. This input is processed by the unified meter control unit in the combination meter, which in turn supplies ground to the left turn signal indicator lamp.

With power and ground supplied, the BCM controls the flashing of the LH turn signal lamps.

RH Turn
When the turn signal switch (combination switch) is moved to the right position, the BCM (body control module) receives input requesting the right turn signals to flash. The BCM then supplies power
- through BCM (body control module) terminal 21
- to front turn signal lamp RH (part of the front combination lamp RH) terminal 6
- to rear turn signal lamp RH (part of the rear combination lamp RH) terminal 3.

Ground is supplied to the front turn signal lamp RH (part of the front combination lamp RH) terminal 4 through body grounds E17 and E43.

Ground is supplied to the rear turn signal lamp RH (part of the rear combination lamp RH) terminal 4 through body grounds B103.

The BCM also supplies ground to combination meter terminals 27 and 28 across the CAN communication lines. This input is processed by the unified meter control unit in the combination meter, which in turn supplies ground to the right turn signal indicator lamp.

With power and ground supplied, the BCM controls the flashing of the RH turn signal lamps.
