PCM Swap

[Pyle]

I just picked up a new pcm and going to put it in, just verifying how to do it.

 

1. disconnect batt

2. open up airbox

3. pull out bolts holding harness into old pcm

4. pull out harness

5. plug in and bolt up harness into new pcm

6. close up box

7. reconnect batt

 

Am I missing anything?

Sounds right for a 2nd gen W.

Be EXTREMELY careful with the plugs for the PCM. They get VERY fragile over time and will break apart.

they do? out of all the J/Y cars I have pulled from and all the times ive swapped my PCM ive never had a connector break or crack even once.

 

yeah the little orange gasket likes to pop off but its easy to put back

 

 

thats ODBII though, ODBI and odb1.5 on the otherhand suck

I'm not sure if it's from the heat or what, but I see '97+ GTP ones break all the damn time.

With a lot of hesitation I swapped them out and started her up, holding my breath of course :? . Everything started up fine and no SES lights came up. Can I assume I did it right?

[manitcor]

yes, you may notice the car slightly stumbling at idle or not running as well as before, this will change over time as the PCM re-learns its parameters for your car.

If the ses light pops on you'll probably need a case learn.
