I also preformed the Auto Active Test and everything seem fine. I thought my battery might be going out cause at times the voltage meter drops low on start up and acts as if it has a hard time starting up. Heading out to get my battery checked now

Well had the battery check and it failed... CCA were low but voltage was around 12.9 with the engine off. Had it replaced with a new one since I had it since I had the truck. Will report back in a few days

Another new guy - I have a 04 titan with 77,000 miles. Here in the last 6 months I have had the slip light - 4lo light and abs light come on just driving down the road then they just turn off after a few minutes. Titan runs fine otherwise. So i get a recall notice to replace ecm. while investigating this problem on google search i find this web site AWESOME. so i take truck in to dealer to have it changed and ask them about IPDM to see if this could cause some of my problems. they said no, so i get home and run the auto active test and guess what ? the horn blows- oil light wont flash - defroster no cycle- headlights no flash- cooling fan no cycle- wipers did come on and ac compressor did not cycle so should i replace ? seems like i flunked test but truck seems to run fine. And thanks to this web site i can now fix my clicking heater module under my dash. Thanks for such a great web site.

I OWN AN 05' TITAN AND I JUST HAD THE ECM RECALL REPLACED AMONGST SEVERAL OTHER THINGS AND NOW MY CATALYST CONVERTER IS GOING OUT A WEEK LATER. MY ECM ACTUALLY WENT BAD AND MY TRUCK WOULD NOT START, SO I WAS FORCED TO TAKE MY VEHICLE IN TO HAVE IT REPLACED. THE ECM HAS TO BE CONNECTED AND RELATED TO THE CATALYST CONVERTER GOING BAD. IS THERE A RECALL ON THE CATALYST CONVERTER? IF NOT THERE SHOULD BE A FREE FIX IF THESE TWO GO BAD WITHIN DAYS OF EACH OTHER.

I've read that a bad IPDM can cause CAT failure. Its worth trying.

04-06 Titans have an electronic module component that has been prone to early failure:

IPDM-ER is the (Intelligent Power Distribution Module in the Engine Room).



Failure Symptoms: Truck can be stuck in "limp mode", erratic flashing lights such as SLIP, 4WD, ABS, Check engine etc., and most importantly the engine dies and can only be restarted after some time!... <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/005.gif' class='bbc_emoticon' alt=':smt005' />

New reports are also showing Titans that won't start up from cold due to a failed IPDM-ER.



Don't look for warning lights or codes to assist you for the diagnosis of a failed IPDM-ER board however there is a "Auto Active Test" feature you can perform easily:

1- Turn the ignition switch on

2- Press the door light activator switch in 10 times........notice the open door light on the dash will flash each time you press the switch.

3- Turn the ignition switch Off then back ON.

4- The horn will beep, oil light will flash, the defroster will cycle, headlights will flash, cooling fan will cycle, wipers will come on and ac compressor will cycle if the IDPM-ER is functioning "NORMAL".



In an Emergency: you may "swap to get you to the shop" the ECM relay & the Fog Lamp relay on the circuit board : but it has been known to only be a very short lived fix.

After the board is lifted up there isn't enough room to lean it back and switch the relays at the bottom with all the wires/plugs in the way so it must come all the way out for a temporary repair.



The OEM warranty on the IPDM-ER is 36 months or 36,000 miles.

Cost of IDPM replacment: Costs from dealers range from ~$180+ to $250 however our vendor Brian at NISSAN PARTS in New Jersey is offering a great price of $92.58 + ship.

Part# for 04-06 Titans is 284B6-ZC00A Be sure to have your Titan year and VIN# for 100% identification when ordering... <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/004.gif' class='bbc_emoticon' alt=':smt004' />



NISSAN has addressed this known electrical circuit board component failure and this is "THE" complete upgraded/improved replacement. <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/023.gif' class='bbc_emoticon' alt=':smt023' />



Removal of the IPDM-ER (Intelligent Power Distribution Module in the Engine Room) circuit fuse/relay board.



The job will take about 30 minutes....I know because I did a "test-run".

Seven plugs on the circuit board must carefully be unlocked with a small flat screwdriver and removed, then the board can be removed for switching the relays or total board replacement.

NOTE-1: This isn't a job I would prefer to do on the side of the road or with a hot engine bay as one must lean over the battery or between the battery and the open hood which is very close quarters...but I could do it if I had to.

NOTE-2: I placed a tarp over the battery and just leaned into the job to stay clean.

1- Remove the battery negative cable first then the positive.

2- Remove the IPDM upper black plastic cover then release the two plastic clips on the IDPM and use a small flat screw driver to push the connector locks inward to release and remove each of the seven plugs.

3- After all the plugs are removed lift the board pull out upside down only.

4- Remove the board and insert the replacement board (or make the temporary relay swap) and reconnect the seven plugs and finally the battery cable(s).

Note: A common pliers tool will assist removal of the relays if a temporary repair is to be used.



Test start your Titan and enjoy!.... <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/023.gif' class='bbc_emoticon' alt=':smt023' /> <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/003.gif' class='bbc_emoticon' alt=':-D' />





For those that need to perform the TEMPORARY relay swap:

(See 2nd picture/diagram below for relays to swap)

Note: A common pliers tool will assist removal of the relays if a temporary repair is to be used.

Three relays have the same numbers on top: NAIS 4 on the left side and on the right side 40814F 1401 Thailand

On the bottom AGM33201 MO8

The 2nd relay down or the ECM relay has NAIS 5 on the left side and on the right side 40919 1913 Japan

On the bottom ACM33211 MO9

NOTE: This is the only relay made in Japan.

The fourth relay down is the Fog Light Relay.

Pin configurations of all relays are the same and consist of four blades.

You must pay attention to put them back in facing the same direction or they won't plug into the sockets properly so take note when removing.

All four relays on the ECM and Fog Light Relay side of the board face the same direction.

All of the relays on the upper five relay side of the board have a NAIS 4 number like the ECM relay side of the board with four relays.







How's the IPDM-ER circuit board work on my Titan!?! :



ECM (Engine Control Module)



The Engine Control Unit or ECU is a designated computer that was developed to manage the engine control system. The ECM consists of electronics which are mounted on multi-layer circuit board.
The ECM monitors and adjusts the air/fuel mixture and utilizes a catalytic converter to minimize amount of pollution produced from the engine. There are two modes of operation, closed loop, which means the computer has completely taking over the operation system. And open loop which is used when the engine is cold and operates on a preset program. The engine must be at operating temperature before it can go into closed loop.



ECM Engine Control Computer



The ECM monitors the input and output signals produced by various sensors in the system. The ECM then adjusts the system as necessary. Sensors can include: oxygen sensor, coolant sensor, mass air flow sensor, air intake sensor, crankshaft angle sensor, throttle position sensor, camshaft angle sensor and knock sensor. The ECM operating program consists of information cells. These cells hold the code for proper engine operation, if information is out side the cell parameters a MIL (malfunction inductor lamp) or "check engine light".



Once a "check engine" or a "service engine soon" light in your instrument cluster has illuminated the ECM has stored a diagnostic trouble code.
This means the computer system on your vehicle has detected a problem with the various systems it controls. Your car or truck has many different sensors that monitor the various vehicle systems. If the trouble code light has been illuminated your vehicle enters into "limp mode" this means it is running on a predetermined program that causes poor mileage and increased emissions. An engine trouble code reader is an easy to use tool. All 1996 and newer vehicles utilize a "D" style plug-in connector that connects to the code reader. On most vehicles the connector is located at the driver's compartment. Once the code reader is plugged in you can retrieve trouble codes the engine computer has stored in its memory. These codes are the same codes the dealer and repair shops use to replace sensors and clear codes.



The ECM outputs a 5 volt reference to most sensors to drive the monitoring circuits. The ECM also controls the radiator cooling fan, air pump controls, fuel pump, EVAP system and more depending on the vehicle. Communication standards have being established in the OBD2 operating system. Among the communication standards controller area networking or CAN has become very popular and can achieve communication speeds of more than 500 Kbps, which is faster than most communication standards.



Advantages of using buses for communication is that if a fault occurs with any of the process modules, it can be reported separately to a diagnostic tool. Manufacturers have different trouble code faults although some are generic. Wiring is simplified by a technique known as multiplexing. In this kind of wiring system is assigned for each module, which consolidates the output and input for that module.



I hope this helps anyone in need or to save $$$!...... <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/004.gif' class='bbc_emoticon' alt=':smt004' /> <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/003.gif' class='bbc_emoticon' alt=':smt003' />

Read everyone's posts last Thursday and Friday...truck would not start...in the driveway, tried everything.(Cranking hard and not turning over.) I replaced the driveshaft sensor, flipped the fog light module out, checked the computer by the door light....every instruction provided. (They were all clear and easy to follow by the way). Had the truck towed to the dealer....turns out, the key my wife used was not set to the same code as the other keys...so the car shut down for security!!! Rule 1...tell wife to take her own car. Rule 2...get one of those diagnostic computers for truck. Brian....any info on one of those?

Welcome to The Spot 05titangreen....

Glad you found the culprit....lol.....and thanks for sharing the experience with the Titan community.

My 2005 Titan 4x4 has the same issues described above. I ran the Auto Active Test and it did exactly what the Haynes guide said it should. Is this indicative of a good IPDM?

I have read that you can switch the relays (fog lamp - IPDM) to test if the relay has gone bad. Any other ideas?



Thanks and take it easy,

Do the switch and if it works bring it to the dealer for a free relay swap and any other recalls your Titan may qualify for.



Good luck and let us know what you find.

Switched relays, still did not start. Issue turned out to be crappy battery. After replacement I am getting ABS and SLIP lights on. Still able to put in 4x4 so currently researching how to clear. I have an XE and do not see any kind of differential switch/button in the cab as the manual mentioned.



Thanks for the quick response and the plethora of valuable information.



Take it easy,
