Moreover, what is a Ipdm Nissan?

IPDM is a Nissan / Infiniti acronym for Intelligent Power Distribution Module. The IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box and fuse block which were originally placed in the engine compartment.

Also, how do I test Ipdm? Here is a way to test the IPDM: Turn the ignition key to the on position, press your door switch 10 times, turn the ignition off then turn it back to the on position. If you do this right your horn will beep and the oil light will start flashing.

Just so, what does Ipdm stand for?

Nissan Sentra Service Manual: Diagnosis system (ipdm e/r) (without intelligent key system)

Diagnosis Description

AUTO ACTIVE TEST

Description

In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation.

  • Front wiper (LO, HI)
  • Parking lamp
  • License plate lamp
  • Tail lamp
  • Front fog lamp (if equipped)
  • Headlamp (LO, HI)
  • A/C compressor (magnet clutch) (if equipped)
  • Cooling fan

Operation Procedure

NOTE:

Never perform auto active test in the following conditions.

  • Passenger door is open
  • CONSULT is connected
  1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper operation)

NOTE:

When auto active test is performed with hood opened, sprinkle water on windshield beforehand.

  1. Turn the ignition switch OFF.
  2. Turn the ignition switch ON, and within 20 seconds, press the driver door switch 10 times. Then turn the ignition switch OFF.
  3. Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test starts.
  4. After a series of the following operations is repeated 3 times, auto active test is completed.

NOTE:

  • When auto active test has to be cancelled halfway through test, turn the ignition switch OFF.
  • When auto active test is not activated, door switch may be the cause. Check door switch. Refer to DLK, "Component Inspection".

Inspection in Auto Active Test

When auto active test is actuated, the following operation sequence is repeated 3 times.

Concept of Auto Active Test


Concept of Auto Active Test


  • IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communication.

    Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto active test starts successfully.

  • The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.

IGNITION RELAY MALFUNCTION DETECTION FUNCTION

  •  IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay-1 inside it.
  •  IPDM E/R judges the ignition relay-1 error if the voltage differs between the contact circuit and the excitation coil circuit.

Ignition relay malfunction detection function

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 relay to protect the starter motor when the starter relay remains active for 90 seconds.

SMART FIELD-EFFECT TRANSISTOR (FET)

SMART FIELD-EFFECT TRANSISTOR (FET) : System Description

System Description

A smart Field-Effect Transistor (FET) is a transistor used to monitor and control current flow on module outputs.

The IPDM E/R uses a smart FET protection strategy to prevent module damage in the event of excessive current flow. The smart FET protection strategy monitors its outputs for excessive current, and when a fault occurs, shuts down the output and records a DTC.

POWER CONSUMPTION CONTROL SYSTEM

POWER CONSUMPTION CONTROL SYSTEM : System Description

SYSTEM DIAGRAM

System diagram

DESCRIPTION

Outline

  •  IPDM E/R incorporates a power consumption control function that reduces the power consumption according to the vehicle status.
  •  IPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN communication.

Normal mode (wake-up)

  •  CAN communication is normally performed with other control units.
  •  Individual unit control by IPDM E/R is normally performed.

Low power consumption mode (sleep)

  •  Low power consumption control is active.
  •  CAN transmission is stopped.

Sleep Mode Activation

  •  IPDM E/R judges that the sleep-ready conditions are fulfilled when the ignition switch is OFF and none of the conditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communication.
  • Outputting signals to actuators
  •  Switches or relays operating
  •  Output requests are being received from control units via CAN communication.
  •  IPDM E/R stops CAN communication and enters the low power consumption mode when it receives a sleep wake up signal (sleep) from BCM and the sleep-ready conditions are fulfilled.

Wake-up Operation

  •  IPDM E/R changes from the low power consumption mode to the normal mode when it receives a sleep wake-up signal (wake up) from BCM or any of the following conditions is fulfilled. In addition, it transmits a sleep-ready signal (not-ready) to BCM via CAN communication to report the CAN communication start.
  •  Ignition switch ON
  •  An output request is received from a control unit via CAN communication.

So my first question is, does this sound legit or like they are trying to screw me? Second, I took a picture of it and it looks like I’m missing one of the switches. Which seems funny because my AC hasn’t kicked on at all since I took it to Nissan. Does anyone else have a pic of their IPDM and is it missing the same spot mine is?

Yes that relay is missing, that space is not used. So ever since you got it back your AC hasn’t worked at all? Do an IPDM auto active test- it’s easy and you can do it in your garage or driveway. This test will help in diagnosing your issue by commanding the compressor clutch on/off 5 times. To start the test have your driver door open and ignition off, turn your ignition on(key on engine off), press the door switch 10 times, turn ignition off then back to the on position. at that point your horn will honk once indicating test start. A series of the following operations repeats three times or until you turn your ignition off.
Oil pressure warning lamp blinks, front wiper lo/hi, park, license plate, side marker, and tail lamps, headlamps, a/c compressor (on and off 5 times), cooling fans. Then it repeats. Again ignition off stops the test.
So what I would do is start the test, grab a flash light and watch for your clutch to engage, you should also hear it. Report back with your findings and based on that go from there on what to do next!

As a former electronic tech that repaired printed circuit boards, but having never removed my own 2006 IPDM board, I will make a few “assumptions” from the above statements.

Yes, relay contacts can get pitted and go bad. However, when the relay was removed & reinstalled then soon thereafter gives problems again, I would suspect defective solder connections on the board to be the culprit. A qualified electronic tech could try to carefully resolder the board with “electrical” solder, not “plumbing acid core” solder. Two problems arise: Some solders are softer than others and will not last. Second, some boards have multi-layered printed wiring that pose difficulty for a good repair. So perhaps that is why Nissan strongly suggests total replacement of the board.

I do appreciate the info given of possible trouble so that should this happen to me I will try to wiggle the relay and hopefully make it home.

Info for the IPDM is found in the Service manual, PG file (Power Supply Circuits), page 25 has the diagram of relay locations.
See: Sticky: Service and other Nissan manuals.

EDIT of 4/2013
Since first reply, I now understand that the maker of the relay had issues during mfg that caused early failure.
