With the ignition switch in the ON or START position, power is supplied
• to ignition relay, located in the IPDM E/R,
• 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)

• through grounds M57, M61 and M79,
• 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 TURN SIGNAL AND HAZARD LAMP OPERATION
The trailer turn signal and hazard lamps are controlled by the BCM through trailer turn relays (LH and RH). If
either turn signal or the hazard lamps are turned on, the BCM supplies 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 turn signal and hazard lamp output is supplied
• through trailer turn relay LH terminal 3
• to trailer connector terminal 1.
Right turn signal and hazard lamp output is supplied
• through trailer turn relay RH terminal 3
• to trailer connector terminal 4.
TRAILER STOP LAMP OPERATION
The trailer stop lamps are controlled by the electric brake. The electric brake receives stop lamp switch signal
when the brake pedal is pressed.
When the brake pedal is pressed, power is supplied
• through electric brake (pre-wiring) terminal 3
• to trailer connector terminal 3.
TRAILER POWER SUPPLY OPERATION
The trailer power supply is controlled by the trailer tow relay 2.
When the ignition switch is in the ON or START position, power is supplied
• through 10A fuse (No. 51, located in the IPDM E/R)
