In this GM Powertrain Control Module (PCM) (aka ECU) reflash video we'll make use of a benchtop programming harness that simulates the GM Off Board Programming Adapter (OBPA) so that we can go over how to replace your 6.5L diesel engine PCM (both trucks and vans) with an used one from a salvage yard vehicle, including reprogramming the correct VIN and latest calibration software level (or of course to a new or remanufactured PCM from GM / ACDelco instead).   This type of PCM is found on all 6.5L diesel engines, particularly the GMT400 trucks aka old body style (OBS) trucks.

You do NOT need this bench top programming adapter harness I'm using to do the repair, you could perform the procedure I go over with the PCM installed in your actual diesel vehicle instead.   However, you WILL need access to a GM Tech2 scan tool as well as the associated GM TIS2000 software, or an acdelcotds.com Tech2Win subscription.

Check that any replacement PCM matches your original ones part number EXACTLY!

The eBay and Amazon search links below are paid links, for which I may be compensated and earn a commission, if you choose to buy the parts and tools shown in this video thru them:

Buy a PCM
It is preferable to use a brand new or factory remanufactured GM / ACDelco PCM for service and repair purposes.  Again documentation may refer to this as an ECU.  The part number for the 6.5L diesel engine for these years was GM 16216588 for C, K, G, and P trucks and vans.  You can search for new 6.5L diesel PCMs, as well as used 6.5L diesel PCMs with part number 16216588: https://ebay.us/nOX9GG or  https://amzn.to/2MKZacG

Buy the GM Service Manual
If you are looking for the GMT400 type GM C/K service manual I was using:  https://ebay.us/z5cENd

Buy a Tech2
If you are looking for a GM Tech2 scan tool as I was using: https://ebay.us/uhEmC2

Buy a Tech2 USB to DB9 Serial Port adapter
And if you need a USB adapter, the GM recommended Tripp Lite Keyspan USA-19HS: https://ebay.us/ZzbYwp or at https://amzn.to/2GEDwE4

If you want to save money, of course you can just use a salvage yard PCM pull which was the point of the video.   Just be sure you pull the PCM with a part number that matches your existing PCM exactly.   I recommend LKQ salvage yards as they let you pull your own parts, and have a no hassle return policy if you pull a dud controller.

WARNING: When performing SPS operations in the actual vehicle, pay very close attention to the service manual instructions around power cabling and battery readiness as a power fluctuation during an SPS programming procedure can permanently damage any controller module.  GM recommends use of their EL-49642 SPS Programming Support Tool (Midtronics PSC-550S) attached to the battery to avoid this.  You can also jumper cable another battery to mitigate this risk.  But do NOT attempt to use a battery charger for this purpose though.

NOTE: TIS2000 was deprecated by GM in early 2008, but was once the primary Techline Information System (TIS) approach delivered to dealers via DVD media.   Today we would use the subscription based TIS2Web of the ACDelco TDS server (www.acdelcotds.com) based offering to accomplish many of the same tasks, although the Off-Board Programming Adapter (OBPA) path shown in this video is no longer supported or offered by TIS2Web unfortunately.

NOTE: Be sure your USB to serial adapter device driver is configured for 115200 speed on Windows using Device Manager and that you set the COM port it is assigned to within TIS2000 for communication to be successful.  GM recommends the Tripp Lite Keyspan USA-19HS adapter (USB to DB9 serial).

And if I've saved you some $$ here, consider some coins for the coffee tip-jar! https://ko-fi.com/drshock
