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 seizure, 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 position 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.

The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-
safe control is activated while the front wiper is set in the INT mode and the front wiper
motor is operating.

INFOID:0000000001697601
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
WARNING:
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.

1. GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2
2. CHECK DTC
1. Check DTC.
2. Perform the following procedure if DTC is displayed.

- Study the relationship between the cause detected by DTC and the symptom described by the customer.
3. Check related service bulletins for information.
Is any symptom described and any DTC detected?
Symptom is described, DTC is displayed>>GO TO 3
Symptom is described, DTC is not displayed>>GO TO 4
Symptom is not described, DTC is displayed>>GO TO 5
3. CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR” mode and check real time diagnosis results.
Verify relationship between the symptom and the condition when the symptom is detected.
>> GO TO 5
4. CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR ” mode and check real time diagnosis results.
Verify relationship between the symptom and the condition when the symptom is detected.
>> GO TO 6
5. PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC Confirmation Procedure for the displayed DTC, and then check that DTC is detected again.
At this time, always connect CONSULT-III to the vehicle, and check diagnostic results in real time.
If two or more DTCs are detected, refer to PCS-38, "
DTCInspectionPriorityChart" and determine trouble
diagnosis order.
NOTE:
Freeze frame data is useful if the DTC is not detected.
Perform Component Function Check if DTC Confirmation Procedure is not included in Service Manual. This
simplified check procedure is an effective alternative though DTC cannot be detected during this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC Confirma-
tion Procedure.
Is DTC detected?
YES >> GO TO 8
NO >> Refer to GI-55, "
Intermittent Incident".
6. PERFORM BASIC INSPECTION
Perform PCS-40, "
Basic Inspection".

SYSTEM DESCRIPTION
PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM controls with the operation of the ignition
switch and performs the power distribution to each power circuit.
If equipped with Intelligent Key, the ignition switch can be operated when Intelligent Key is in the detection
area of the interior antenna.
The ignition switch operation is input to BCM as a signal. BCM changes the power supply position according
to the status and operates the ignition relay (inside IPDM E/R) to supply power to each power circuit.
