IPDM E/R (INTELLIGENT POWER DI
STRIBUTION MODULE ENGINE ROOM)
IGNITION RELAY MALFUNCTION DETECTION FUNCTION
• IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
• IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation
coil circuit.
• If the ignition relay cannot turn OFF due to contact seiz ure, it activates the tail lamp relay for 10 minutes to
alert the user to the ignition relay malfunction when the ignition switch is turned OFF.
NOTE:
The tail lamp turns OFF when the ignition switch is turned ON.
FRONT WIPER CONTROL
IPDM E/R detects front wiper stop posit ion by a front wiper auto stop signal.
When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 second activation and 20 second stop five times.
NOTE:
This operation status can be confirmed on the IPDM E/ R “Data Monitor” that displays “BLOCK” for the item
“WIP PROT” while the wiper is stopped.
STARTER MOTOR PROTECTION FUNCTION
IPDM E/R turns OFF the starter control relay to protect the starter motor when the starter control relay remains
active for 90 seconds.
DTC IndexINFOID:0000000009461605
NOTE:
The details of TIME display are as follows.
• CRNT: The malfunctions that are detected now
• 1 - 39: The number is indicated when it is normal at present and a malfunction was detected in the past. It
increases like 0 → 1 → 2 ··· 38 → 39 after returning to the normal condition whenever IGN OFF → ON. It is
fixed to 39 until the self-diagnosis results are erased if it is over 39. It returns to 0 when a malfunction is
detected again in the process.

< PERIODIC MAINTENANCE >
REAR SUSPENSION ASSEMBLY
• Check the wheelarch height in the unladen condition. Refer to RSU-17, "Wheelarch Height (Unladen*1)".
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
• This type of alignment is recommended for any NISSAN vehicle.
• The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.
• The alignment machine itself should be ca pable of accepting any NISSAN vehicle.
• The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated. • Your alignment machine should be regularly calibrated in order to give correct information.
• Check with the manufacturer of your specific al ignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-17,
"Wheelarch Height (Unladen*1)".
1. When displaying the alignment settings, many alignm ent machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
• The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.
• This may result in an ERROR.
2. Most camera-type alignment machines are equipped with both "Rolling Compensation" method and optional "Jacking Compensation" method to "com pensate" the alignment targets or head units.
"Rolling Compensation" is the preferred method.
• If using the "Rolling Compensation" method, after installing the alignment targets or head units, push or pull on the rear wheel to move the vehicle. Do not push or pull the vehicle body.
• If using the "Jacking Compensation" method, after in stalling the alignment targets or head units, raise
the vehicle and rotate the wheels 1/2 turn both ways.
NOTE:
Do not use the "Rolling Compensation" method if you are using sensor-type alignment equipment.
• Follow all instructions for the alignment machine you are using for more information.
CAMBER and TOE
• Camber and toe are both set by adjustment of the fr ont lower link and rear lower link adjusting bolts.
1. Loosen the nuts at the adjustment points on the front lower link and rear lower link.
2. Adjust the camber and toe by turning bolt (1) on front lower link (2).
3. Adjust the camber and toe by turning bolt (1) on rear lower link (2).

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.
