Status: offline ok, so thanks to this sight and hours on the comp. i found out how to get my error codes up..... i found out what they mean... sorta.... what do these codes mean in lamen terms??
how do i fix these thigs?....also could one of these be the reason i cant start my car(wont crank)....

1) IO34= loss of powertrain control modul data.
2) IO52= keep alive memory error.
3) AO12= low side tempratur sensor.
4) TO73= pcm-EBTCM/EBCM pulse width modulation signal fault
5) TO72= serial data link fault
6) SO22=??????
7) SO36= electronic level control compressor short to ground open
8) SO44= lift or drive signal open

(THANK YOU TO EVERYONE WHO HAS OR WILL HELP ME WITH MY CADDY PROBLEMS!!)

Status: offline I see u just posted recently. I`m not a tech, but i can see u have some (serious)probs that I`m sure the dudes on this site will understand. I`ll guess you`re going to need in depth diags from a tech with a tech tool. Be prepeared to pay.(?)
The only thin i can answer is coming out of obdiags, it`s asking you, (first) if you want to go into pcm diagnostics in-depth.
To escape, you just hit "off" button I think I remember.
Good luck bro`.

are those codes tagged CURRENT or HISTORY ?
really important to get THAT answer .. pull the codes again and verify CURRENT / HISTORY on each one.

IF they are current, all of them together, you got problems .. some options:

when you pulled the battery,
- a harness was disconnected or damaged
- the cables were placed on the wrong terminals of the battery, damaging electronic components
- something got shorted out and fried

have you ever heard the advice of not jumping another car battery?
things like this can happen when everything is not perfect.
i know you didnt jump another car, but the effects may be similar.

1st one sounds like the fuel pump or a fan.

2nd one sounds like a DEAD battery or BAD GROUND.

Status: offline THANK YOU, and sorry about not putting which are history and which are new...

1) IO34= CURRENT: loss of powertrain control modul data
2) IO52= history
3) AO12= CURRENT : low side temp sensor
4) TO73= CURRENT : pcmEBTCM/EBCM pulse width modulation signal fault
5) TO72= CURRENT : serial data link fault
6) SO22= history
7) SO36= history
8) SO44= history

the four that have what they are written are CURRENT! thank you to every one who is helping me...

Status: offline My first thought is a very weak or very dirty (corroded ) battery connection. Battery needs to be slow charged for awhile and the cables to it removed and cleaned. The noises described are consistant with a weak battery or poor connection. The " pulse width" clue has to do with allowing the injectors to spray fuel, but me thinks the lack of strong battery voltage could set this related code. So, #1 remove battery and slow charge overnight. #2 load test battery after charge to verify its OK. #3 clean battery cable ends and reattach. If it starts, erase ALL codes then after 2 or 3 days do another code search thru diagnostics and report back.
