General Precautions for Service OperationsNKS003NX
Never work with wet hands.
Xenon headlamp includes high voltage generating part. Be sure
to disconnect battery negative cable (negative terminal) or
power fuse before removing, installing, or touching the xenon
headlamp (including lamp bulb).
Turn the lighting switch OFF before disconnecting and connect-
ing the connector.
When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.
When checking the headlamp on/off operation, check it on vehi-
cle and with the power connected to the vehicle-side connector.
Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
Install the xenon headlamp bulb socket correctly. If it is installed improperly, high-voltage leak or corona
discharge may occur that can melt the bulb, connector, and housing. Do not illuminate the xenon head-
lamp bulb out of the headlamp housing. Doing so can cause fire and harm your eyes.
When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor-
mance of the lens and reflector (dirt, clouding). Always prepare a new bulb and have it on hand when
replacing the bulb.
When adjusting the headlamp aiming, turn the aiming adjustment screw only in the tightening direction. (If
it is necessary to loosen the screw, first fully loosen the screw, and then turn it in the tightening direction.)
Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

General Information for Xenon Headlamp Trouble DiagnosisNKS003P2
In most cases, malfunction of xenon headlamp - "does not illuminate", "flickers" or "dark" - is caused by a mal-
functioning xenon bulb. A HID control unit or lamp housing, however, may be a cause of malfunction. Be sure
to perform trouble diagnosis following the steps described below.
Caution:NKS003P3
Installation or removal of connector must be done with lighting switch OFF.
Disconnect the battery cable from the negative terminal or remove power fuse.
When the lamp is illuminated (when lighting switch is ON), never touch harness, HID control unit, inside of
lamp, or lamp metal parts.
To check illumination, temporarily install lamp in vehicle. Be sure to connect power at vehicle side connec-
tor.
If error can be traced directly to electrical system, first check for items such as blown fuses and fusible
links, broken wires or loose connectors, dislocated terminals, and improper connections.
Never work with wet hands.
Using a tester for HID control unit circuit trouble diagnosis is prohibited.
Disassembling HID control unit or harnesses (bulb socket harness, ECM harness) is prohibited.
Immediately after illumination, light intensity and color will fluctuate, but there is nothing wrong.
When bulb has come to end of its life, brightness will drop significantly, it will flash repeatedly, or light color
will turn reddish.

In most cases, malfunction of xenon headlamp - “does not illuminate”, “flickers” or “dark” - is caused by a mal-
functioning xenon bulb. A HID control unit or lamp housing, however, may be a cause of malfunction. Be sure
to perform trouble diagnosis following the steps described below.
CAUTION:NKS003PS
Installation or removal of connector must be done with lighting switch OFF.
When lamp is illuminated (when lighting switch is ON), do not touch harness, HID control unit, inside of

To check illumination, temporarily install lamp in the vehicle. Be sure to connect power at the vehicle-side

If the error can be traced directly to the electrical system, first check for items such as burned-out fuses
and fusible links, broken wires or loose connectors, pulled-out terminals, and improper connections.
Do not work with wet hands.
Using a tester for HID control unit circuit trouble diagnosis is prohibited.
Disassembling the HID control unit or harnesses (bulb socket harness, ECM harness) is prohibited.
Immediately after illumination, the light intensity and color will fluctuate, but there is nothing wrong.
When the bulb has reached the end of its lifetime, the brightness may drop significantly, it may flash
repeatedly, or the light may turn a reddish color.

ILLUMINATION
Revision: 2007 April2007 M35/M45
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU located in the IPDM E/R controls the tail lamp relay coil,
which, when energized, directs power
through IPDM E/R terminal 21

EXTERIOR LAMP BATTERY SAVER CONTROL
BCM activates the exterior lamp battery saver control function and turns off the exterior lamps to prevent bat-
tery from over discharge when the combination switch (lighting switch) is in 1ST or 2ND position and/or the
front fog lamp switch ON and the door lock operation is performed by keyless entry system.
CAN Communication System DescriptionNKS003TI
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS003TJ
Refer to LAN-50, "CAN System Specification Chart" .

OIL PRESSURE CHECK
WARNING:
Be careful not to get burn yourself, as engine oil may be hot.
Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
Remove the oil pressure switch using a 26 mm (1.02 in) box
wrench. (AWD models)
4. Install the oil pressure gauge (SST) and hose (SST).
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load.
NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
Unit: [kPa (kg/cm2 , psi)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
