Remote Keyless Entry System Operation

Power is supplied at all times
- to BCM (body control module) terminal 7
- through 50 A fusible link [letter F, located in the fuse and fusible link box], and
- to combination meter terminal 43
- through 10 A fuse [No.19, located in the fuse block (J/B)].

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

When the remote keyless entry system is triggered by input from the keyfob, the BCM supplies power
- through BCM 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
- through BCM 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 LH (part of the front combination lamp LH) terminal 4 through body grounds E17 and E43
- to the front turn signal lamp RH (part of the front combination lamp RH) terminal 4 through body grounds E17 and E43

- to the rear turn signal lamp LH (part of the rear combination lamp LH) terminal 4 through body grounds B103
- to the rear turn signal lamp RH (part of the rear combination lamp RH) terminal 4 through body grounds B103.

The BCM also supplies input 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 and right turn signal indicator lamps.

With power and ground supplied, the BCM controls the flashing of the hazard warning lamps when keyfob is used to activate the remote keyless entry system.
