What does it cost to rebuild my PCM?
The price for rebuilding any model of 7.3 PCM is $475.00. If you are ordering a rebuilt PCM from our website, the $600.00 price you see is $475.00 for the rebuilt PCM plus a $125 core charge which is refunded as soon as we get your old PCM back.
If you are sending your own PCM in for a rebuild, don't place the order on line, or you will get charged the $125 core charge. We will refund it if you do that.
If you have sent your PCM in for testing, and paid the $45.00 testing fee in advance, we deduct that from the rebuild price, so your balance due would be $430.00.
We generally get testing done the same day we receive your module in, and email you our findings as soon as we are finished testing. Orders that arrive on a Friday afternoon may not get tested until Monday morning.
We make every effort to keep pretty much everything we sell in stock, so if your module is found to be bad, we should have a replacement we can ship out, so you don't have to wait for us to repair your unit.
One exception is 7.3 Excursion PCM's: If you want to keep the PATS active, which is stored in the EEPROM in the PCM, we will rebuild your PCM and return it to you. Note that if your EEPROM is fried, we will have to replace it, and then it will no longer be possible to activate PATS, neither by us, or anyone else.
I sent my PCM to another company, and they said its not repairable.
Send it in to us anyway. We have a better than 95% success rate in rebuilding 7.3 PCM's. The two main issues we can't fix are severely burned circuit traces on the printed circuit board, and fired EEPROM's on the DPC-202 and 203's. And, even if we can't fix it, we'll still sell you a rebuilt unit and not penalize you with a core charge. [It's not your fault if we can't fix it! ;) ]
Do you need the VIN and Odometer Mileage?
Not really. The 7.3 did not come with the VIN programmed into the PCM from the factory, and nothing on the truck is dependent on having the VIN programmed in for proper functionality, although having the VIN in the PCM does make it a lot easier for some scan tools to correctly identify the vehicle. The mileage on a 7.3 is not stored in the PCM, but in the instrument cluster. We do ask for your mileage on our Customer & Vehicle Information Sheet because it is helpful to understand the effects of age on the various components on the truck.
PATS (Passive Anti Theft System) and Excursion PCM's
>>>If we have to replace the EEPROM in an Excursion PCM, PATS will be permanently disabled.<<<
All Excursions are equipped with Ford's PATS and while some people like it, others hate it. The PATS is a 2-part system: The PCM, and the PATS module, which is a black box under the dash about 10” above the accelerator pedal. When you turn the key-on, the PATS module checks to see if the PCM is the correct unit. If it is, it tells the PCM its OK to start the engine and fire the injectors; if something is amiss, the PCM will fire the injectors during cranking, but if the engine RPM goes above about 350 RPM, the PCM shuts down the injectors after two seconds. Disabling PATS in the PCM is as simple as finding the “switch” in the code, and changing a 0 to a 1. However, if you put a different (PATS enabled) PCM in the vehicle the PATS module will not accept it, and the vehicle won't start, unless the PCM in reprogrammed with the Ford IDS scan tool. The PATS information is stored in the EEPROM, but the Ford IDS does not recognize our EEPROM's as being correct, so it will not reprogram the PCM, which in turn means PATS cannot be re-enabled. For this reason, if you want to keep PATS active, you need to send your PCM in for a rebuild. If the EEPROM is still good, PATS will work normally. If the EEPROM is bad, we will have to replace it, and PATS will no longer be possible.
Why should I send my PCM in for testing first?
Because... close to half of the time that someone buys a PCM without testing their old one first, the “core” they send back is in perfect working condition. Testing is $45 and rebuilt PCM is $475, so you decide if you want to take the gamble. :) Two exceptions to this are if you have pulled the chip out with the key on or the engine running, and now (with or without the chip) all you get is a steady CEL on when you try to start the truck, then the PCM is almost certainly fried. Or, if you have swapped in a known-good test PCM, and the issue went away, and the issue returned again when you put the suspect PCM back in the vehicle. This last point is critical—a poor contact on one of the connector pins can be fixed just by removing and reinstalling the PCM plug!
Should I put dielectric grease on the PCM terminals?
We don't think so.
- The pins and sockets on the PCM connector are gold plated, and gold is completely corrosion and oxidation resistant.
- Not all brands of dielectric grease are truly dielectric (non-conductive). International had so many problems with their ECM's/ECU's which were traced back to low quality dielectric grease that they came out with their own brand of grease, and refused warranty claims on all ECM's that had dielectric grease on them that wasn't theirs. Every IH ECM even has a label on it specifying the part number of that grease, 1831731C1, and other manufacturers such as Detroit Diesel even specify it on their ECM's!
- If you live near enough to the ocean that salt corrosion is an issue, live in northern states where roads are salted in the winter, or do off-road driving in mud and water, using dielectric grease may be a good idea—but only if you use 1831731C1!
