Keyless Entry Operation

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 5
- through 10 A fuse [No. 19, located in the fuse block (J/B)].

Ground is supplied
- to BCM terminals 8, 27, and 63,
- through body grounds M57, M61, E15, and E24, and
- to combination meter terminals 6 and 39
- through body grounds M57 and M61.

When the remote keyless entry system is triggered by input from the keyfob, the BCM supplies power
- to front turn signal lamp LH terminal 3
- to front turn signal lamp RH terminal 3
- to rear turn signal lamp LH (part of the rear combination lamp LH) terminal 3
- 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 terminal 2 through body grounds E15 and E24
- to the front turn signal lamp RH terminal 2 through body grounds E115 and E129
- to the rear turn signal lamp LH (part of the rear combination lamp) terminal 5 through body grounds B7 and B19
- to the rear turn signal lamp RH (part of the rear combination lamp RH) terminal 5 through body grounds B7 and B19.

The BCM also supplies input to combination meter terminals 1 and 2 across the CAN communication lines. This input is processed by the central processing unit of 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.
