When it comes to calculating my costs, I should tell you I work for myself. I look for vehicles in this condition & purchase them, repair them & sell them. I only like doing things one way, the right way. My funds aren't unlimited so Of course I want to avoid replacing anything that doesn't need to be replaced.
But what ever it takes to get it done right is what I will do, and my labor is my most abundant asset.
Now, the more I think about the SRS module, the more I wonder how 'they' (it was myairbag. Com) where able to determine 'internal failure', especialy since the airbags have never been deployed & the vehicle never wrecked. Although I need to make sure the SRS system is fully functional before I sell the vehicle, my main concern for now is the mil lights, & main goal over all is for the vehicle to be without any mechanical needs period.
Lets focus on the BCM & ECM, I want to be certain that they need to be replaced, before replacing them (which will also mean reprogramming them) & that there is nothing existing that will cause the replacements to fail.
Even with the combination of information from Alldata, repairpath, & chilton, I am still unsure about which module is responsible for illuminating the mil lights or how to be certain if a specific module is bad.
I actually infact have not spent alot of money in parts. The ign coil pack is been the most so far.
I was left confused with your last set of instruct. About "we should check the connection
( wire) between the BCM and the PCM." According to the diagram I have for the PCM, there are 2 wires that are responsable for this. They are Tan & Tan w/white they are labled BCM CAN HI & BCM CAN LOW. Other than verifying that there is no loss in conection from one plug to the other (which I have & they are good) is there any way to check the signal going between them? IF ANYTHING most of all thats I need to know from you for now.
Also the diagram you sent covers everything for the auto-doorlock system which checks out just fine.
I do have a brand new developement with the vehicle. It died the other day right about the time it reached operating temp (185). For the first time ever I got some DTC's out of it when it happened. Of course if you let it cool, starts back up. Sounds like PCM has failed & as soon as it leaves limp mode, it dies. The codes stored were p0727 engine speed sensor signal, 1810 trans fluid pressure position switch, & p0443 evap purge silinoid control circut.
Where in the hell is the engine speed sensor on this, I found the cam & crank position sensors, but can't find in any componate location chart that tells where the speed sensor is.
I am shopping arround for a tech tool capable of handling the programming and calibration of the PCM, BCM & ECU type, any suggestions.
Take your time and read over this more than once because I know I get consfusing, & if you say it's time to, the BCM will be the next on the list to be replaced, or if you think we should check something else out first let me know.
P.S. Bought the car for 600 & have about another 200 invested so far, so if I can get this all worked out for under 800-1000 I'll be ok.
