#7.3 IDM REPAIR SOFTWARE#
I have a feeling that your techline is correct- they may have made a software change in some IDMs that is more forgiving of the hammered poppets and won't set a circuit code for it, the second IDM you put in probably had different software that did not include this.
#7.3 IDM REPAIR DRIVER#
I couldn't find the IKnow letter about it, but I found a reference talking about a 525 injector driver circuit code which referred to the shim kit PN 2594407C91 which is a couple thousand dollars. If you have the VC off again for some reason I'd pull the magnet(s) on the associated injectors, use brakecleen and shop air to clean the accumulated metallic crud from the area, and verify there is clearance under the reluctor with a feeler gauge. IH had a big problem with this years ago but they didn't want to change out a bunch of injectors so their fix was to issue a large repair kit (designed to fix lots of injectors) where you removed the magnet, measured the height of the reluctor (square plate bolted to the poppet), and changed the aluminum spacer to a thinner one to correct the height due to the poppet seat hammering out. A side note is that IH's set an injector circuit fault on this engine when the injector poppets hammer out on older injectors, I remember something about the amperage increases above what is normal the the ECM sets a circuit code.
I haven't heard of the company but it obviously sounds like you have a bum IDM. I think Ford should just buy back their IDM and let the customer buy the aftermarket one. I looked on their website and the IDM cost $165 but the customer paid $930 for the Ford one. Why are they still selling the IDM if they know there is a problem? What would the internal hardware in the IDS have to do with the CEL coming on? Ford warranty does know that we are making these recommendations for this type of repair. We will want to change this part out as a SPW warranty and OSP (outside part). We will want to contact Website: and order (Part number listed on their site as Ford PN XC3Z12B599AA)Sales Ph: 85. But we would like you to get the IDM from an outside source. Since the code does not set when you use your test IDM and the code is now setting at idle where it was only under a load before. We have actually determined that the internal hardware in the IDS is too sensitive causing the P1276 codes to set. Now get ready for it, here's their reply. Parts Replaced: IDMīefore I try another IDM is it possible the software in the new IDM is more sensitive to set a light for the codes listed than the older IDM's and it's picking up a problem with injectors 4 and 6 when it is running and not on KOEO? When I clear the codes and run the KOEO self test and KOEO injector electrical test the codes don't come back until you start it and make the light come back on.
The P1276 comes back and now I have P1274. Insalled an OEM rebuilt IDM and now the CEL comes on after you start it and let it idle for 10 seconds and it stays on. I installed a test IDM and went on a long test drive and the CEL never came on. Engine doesn't miss at any time, even when the light is flashing. Pulled valve cover and checked injector harness connector and ohm tested injector, all okay.
#7.3 IDM REPAIR FULL#
When the codes are cleared the P1276 won't come back until after it is driven and you make the CEL flash by driving at full throttle up a hill. Diagnostics Performed: KOEO self test and KOEO injector electrical test and had codes P0475 and P1276. Here's what I sent to the hotline describing the problem.ĭescription of Vehicle Concern: Check engine light flashes when under heavy acceleration. I have a 2002 F-550 with 129,000 miles and the following problem.
