@checkenginechuckllc: A lot more testing was done than i show in this video! This was my second visit to install the #ecm ! I have never seen where just touching a can network with the #powerprobe or #breakoutbox but that extra little load must of helped overload the #terminating #resistor ! #cannetwork #diagnosis

I’d read the description. I watched the video fully. I’m curious to know what process wasn’t shown as I want to know why we have an internal PCM failure. ⬇️

99% of the time it's not the ecm, unless it's a John Deere. Then it's 50/50 😭

Most PCM’s past mid 2000 are legit, the issues lie with fuses, relays and other component modules 99.999999% of the time 👍🏻

Except when you do all testing and service info tells you to replace PCM. and its still not it. PS it was the starter causing the crank code on the honda I worked on. 😂

Man you would’ve loved the car I had yesterday. 21 F-150 none of the interior lights worked. Had power at the fuses and going to the bcm but bcm was not switching lights on.

I programmed a new PCM for a shop that was certain it was a bad PCM after they had done new heads & it wasn't starting. I told em it was timing. New PCM did not fix the issue. 3 months later
