7.3 PCM Resolder Chip TerminalsDiesel Technology of Chattanooga
We can resolder the chip contact terminals on your PCM.
The PCM circuit board is dipped in a conformal plastic coating after manufacture to protect it from moisture, etc. This coating must be removed to install a performance chip, but unfortunately a lot of people remove not just the coating, but the solder also, revealing the copper circuit traces below. The copper then tarnishes, preventing a good electrical contact between the chip and the terminals.
This can cause major problems; if you get lucky, your truck will just stall or not start. If you are unlucky, this will fry the PCM and the chip.
If you send your PCM in for testing, and the terminals need resoldered, we'll contact you to see if you want them fixed.
