If your truck is a 1994.5-1996 and want to get the PCM updated to have full OBDII capabilities with a scan tool, choose this service. If the "tear tag" on the PCM access cover or connector label reads TDE0/TDE1 (Auto Trans) or MLE0/MLE1 (Manual Trans), then no updates are needed.

If your truck is a manual trans and the code is BEGx, which has no OBDII capability at all, this will make it fully functional.

All flashes include test running the PCM before and after programming to verify proper functioning.

As a general rule, flashing does NOT fix anything that is wrong with the truck, except for TSB issue
