Remote Keyless Entry System Operation

Power is supplied at all times

to BCM (body control module) terminal 55
through 50A fusible link [letter F, located in the fuse and fusible link box], and
to combination meter terminal 43
through 10A fuse [No. 19, located in the fuse block (J/B)].

Ground is supplied

to BCM terminal 52
through grounds M30 and M66, and
to combination meter terminals 45 and 46
through grounds M30 and M66.

When the remote -keyless entry system is triggered by input from the keyfob, the BCM supplies power

through BCM terminal 45
to front combination lamp LH terminal 6
to rear combination lamp LH terminal 3
through BCM terminal 46
to front combination lamp RH terminal 6
to rear combination lamp RH terminal 3.

Ground is supplied

to the front combination lamp LH terminal 4 through grounds E17 and E43.
to the front combination lamp RH terminal 4 through grounds E17 and E43.
to the rear combination lamp LH terminal 4 through ground B103.
to the rear combination lamp RH terminal 4 through ground 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 key fob is used to activate the remote keyless entry system.
