PCM removal help

[obs97stroker]

i removed my Pcm when i put in my ts chip and it was the biggest pain in the a** i have ever had... does any one have a easy way to take it in and out be cause i am getting a code PO603 and i think its something to do with the chip being loose so the PCM will have to come out soon and any advice would be appreciated.

P0603 is the Keep Alive Memory code which you usually get if the batteries have been disconnected. Other than removing the wheel arch trim and then removing enough of the inner plastic wheel well mounting screws so you can flex the inner well out of the way enough to remove the PCM, I can't come up with anything easier. Cheers!

It's easy as pie. Unbolt the wheel well liner from the underside and pull it down. PCM will have enough room to pull out into the engine bay. Easy as that!

***Edit*** Dang, Patrick beat me to it.

Wait -- do you need to remove the PCM from the truck to install/remove a chip? Don't you just do it from the inside, by removing the parking brake handle assembly?

[marine5811]

It's much more precise to do it with the pcm pulled. That way you can see well and easily install the chip properly. You can also clean the contacts much better with the pcm out.

ok thanks for the responses i didnt remove the wheel well liner the first time thats why it was so hard it took a pry bar haha... and yeah its best to remove the pcm to install a chip cause you have to open the pcm and clean the surrface before connecting it
