TRAILER TOW
Revision: October 20052005 QX56
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, and

to electric brake (pre-wiring) terminal 1

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

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. If either turn signal or the hazard lamps
are turned on, the BCM supplies voltage to the trailer lamps to make them flash.
Left turn signal and hazard lamp output is supplied

through BCM terminal 52

to trailer connector terminal 1.
Right turn signal and hazard lamp output is supplied

through BCM terminal 51

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)

through IPDM E/R terminal 16

to trailer tow relay 2 terminal 1.
When energized, the trailer tow relay 2 supplies power

through trailer tow relay 2 terminals 5 and 7

to trailer connector terminal 5.

5. Install Tools.
6. Start the engine and warm it up to normal operating temperature.
7. Check the engine oil pressure with engine running under no-load.
Engine oil pressure [Engine oil temperature at 80°C (175°F)]
Unit: kPa (kg/cm2
, psi)
CAUTION:
If the difference is extreme, check the oil passages and oil pump for leaks and blockages.
8. After the inspections, install oil pressure sensor as follows:
a. Remove old liquid gasket adhering to oil pressure sensor and engine.
b. Apply liquid gasket and tighten oil pressure sensor to the specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-45, "
Recommended Chemical Prod-
ucts and Sealants" .
c. After warming up engine, make sure there is no leakage of engine oil with engine running.
