through IPDM E/R terminal 61
to trailer tow relay 1 terminal 3, and
through 20A fuse (No. 53, located in the IPDM E/R)
to CPU (central processing unit) of the IPDM E/R, and
through 30A fusible link (letter j , located in the fuse and fusible link box)
to trailer tow relay 2 terminals 3 and 6, and
through 40A fusible link (letter k , located in the fuse and fusible link box)
to electric brake (pre-wiring) terminal 5.
With the ignition switch in the ON or START position, power is supplied
to ignition relay, located in the IPDM E/R, and
through 10A fuse (No. 59, located in the fuse and relay box)
to BCM terminal 38, and
through 10A fuse (No. 51, located in the IPDM E/R)
to trailer tow relay 2 terminal 1.
Ground is supplied
to BCM terminal 67
to electric brake (pre-wiring) terminal 1, and
through grounds M57, M61 and M79, and
to IPDM E/R terminals 38 and 59
to trailer tow relay 1 terminal 2
to trailer tow relay 2 terminal 2, and
to trailer connector terminal 2
to trailer turn relay LH and RH terminal 2
through grounds E9, E15 and E24.
TRAILER TAIL LAMP OPERATION
The trailer tail lamps are controlled by the trailer tow relay 1.
With the lighting switch in the parking and tail lamp ON (1ST) position, AUTO position (and the auto light sys-
tem is activated) or headlamp ON (2ND) position, power is supplied
through the tail lamp relay, located in the IPDM E/R
through 10A fuse (No. 36, located in the IPDM E/R)
through IPDM E/R terminal 49
to trailer tow relay 1 terminal 1.
When energized, trailer tow relay 1 supplies tail lamp power to trailer connector terminal 6.
TRAILER BRAKE, TURN SIGNAL AND HAZARD LAMP OPERATION
The trailer brake, turn signal and hazard lamps are controlled by the BCM through trailer turn relays (LH and
RH). When the brake pedal is depressed, the BCM receives stop lamp switch signal through CAN communi-
cation. If the brake pedal is depressed or either turn signal or the hazard lamps are turned on, the BCM sup-
plies voltage to the trailer turn relays (LH and RH) to make them cycle on and off.
Trailer turn relay LH output is supplied
through BCM terminal 52
to trailer turn relay LH terminal 1.
Trailer turn relay RH output is supplied
through BCM terminal 51
to trailer turn relay RH terminal 1.
Left trailer brake, turn signal and hazard lamp output is supplied
through trailer turn relay LH terminal 3
to trailer connector terminal 1.
Right trailer brake, turn signal and hazard lamp output is supplied
through trailer turn relay RH terminal 3
