ERROR CODE MEANINGS/ FIXES??
 

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!!)

P.S.... it is a 1994 cadillac seville sts....... THANK YOU

RE: ERROR CODE MEANINGS/ FIXES??
 

it ALSO says
1) NO SIR
2) NO PCM CURRENT
3)then wen all codes are doneshowing (PCM?) stays there

SORRY ABOUT NOT MENTIONING!!!

RE: ERROR CODE MEANINGS/ FIXES??
 

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 atech 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`.

thanks man, i hope someone can help me figure out why its not craking with this post and my other one someone should know or have a clue

RE: ERROR CODE MEANINGS/ FIXES??
 

new info. wen i turn the key like im going trying to start it it makes a buzzzzing sound almost like a little electric motor and also does a slight repetative clicking noise

RE: ERROR CODE MEANINGS/ FIXES??
 

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.

RE: ERROR CODE MEANINGS/ FIXES??
 

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

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

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...

RE: ERROR CODE MEANINGS/ FIXES??
 

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.

listen to carnut ..

also, slowroll, our resident GM mechainc just jumped in via email .. he is caught up in a bad strom ...

what slowroll says will work if the advice from carnut is applied BEFORE you do the tests.
meaning, bad connections wont serve you at all.

these two guys are good .. damn good ...

=====================================

HI, BEEN A WHILE. REVIEW MY PREVIOUS POSTS MAY FIND ANSWER.

CHECK BATTERY VOLTS ON DIC 12.0+ BATTERY CONNECTION MY BE OK. WITH VOLTMETER ON BATTERY WHAT DOES IT READ, THEN WHAT DOES IT READ WHEN TURNED TO ON THEN AGAIN TO CRANK/START?
CHECK FOR 12V ON PURPLE WIRE JUMPER AT RIGHT END OF REAR VALVE COVER WITH KEY IN CRANK.

BAD STARTER COULD BE PULLING BATTERY VOLTS BELOW 10.0v SETTING CODES. CODES WHEN CLEARED WHAT COMES BACK?

I WILL BE RIDING STORM OUT THIS WEEKEND. I WILL CHECK E MAIL MONDAY OR TUESDAY.

RE: ERROR CODE MEANINGS/ FIXES??
 

i did all that but when i used the voltage meter it only said 13.1.....
i cleaned the battery connections (again) tightend them up.....
and it did the same thing (when i tun the key it will click and "buzzz" under the hood)

RE: ERROR CODE MEANINGS/ FIXES??
 

ohh, stealth i didnt read yoursuggestion before my last reply didnt relize there was 2 pages....
the voltage on my volt-meter and in the dash read are the same....
i cant see what the voltage is when in try and crank it cause no one is around to turn the key for me....and all the dash light and everything radio etc... go off when i turn the key like im trying to start it....so no dash readout on the volts for when im trying to start...?,..

were is the starter located at so i can take it in to advance to see if its good?...
i dont remember were i herd it from...but can the starter go out if the battery doesnt put out enough juice even one time?....



P.S. theres a couple groups of wires next to each other and one of them has like four PUPLE wires..and there in a tight spot so cantrealy test any...P.I.T.A

RE: ERROR CODE MEANINGS/ FIXES??
 

Can you get a loaner battery from someone to confirm thats not the problem?

RE: ERROR CODE MEANINGS/ FIXES??
 

Please put year and type of Cad in your signature profile like I did, so we dont have to scroll back 2 pages just to find out what you own. Thanks

RE: ERROR CODE MEANINGS/ FIXES??
 

ok i bought a brand new battery, and i put brand new terminals on.... nothing changed..
still makes a tick when i try and start it.... im EXTREMLEY pissed off ....
i even tested the battery to make sure its good....im stuck!

ANYMORE SUGGESTIONS???

RE: ERROR CODE MEANINGS/ FIXES??
 

i took the starter in to advace and they tested it...it was bad...so i bought a new one and my car still wont crank over!!!!!!!! so pissed off i almost wanna take it to a junk yard.....

RE: ERROR CODE MEANINGS/ FIXES??
 

bench test it .. there are a lot of defective units in the REM world.



from slowroll, TECH :

new terninals? why? if copper is discolored green or rust red, you need cable(s) applies to both positive and negative. being starter buzzes i doubt engine is locked up. be sure new starter is good also sometimes the lowest priced is not the best product.

RE: ERROR CODE MEANINGS/ FIXES??
 

the starter was brand new it WASN'T a rebuilt one...
cause the previous owner stipped out the bolt that goes to the old one for like$1 more than just the bolt you get both the terminal/bolt so why not?....
how would i see if my motor is locked up...???
ooohhhh, yeah almost forgot the guy said it looked like i had put the terminals on backwardsOR it shorted out somehow cause the bolt had (something on it i forget).....i know for a fact that i dint put them on backwards...

and the starter isnt what was buzzing its something else... when i took it in i watched them test it...and that was what was making the click every time they pushed the button... (sounded just like when it was in the car)...

RE: ERROR CODE MEANINGS/ FIXES??
 

1. BENCH TEST the starter ! ! ! ! ! ! ! !

2. put a wrench on the crank and turn the engine !

3. OK .. that is two people saying that.

It happens even when one believes it didnt it .. it can happen so fast in ways that you dont even need the cables to do damage .. keys, wrench, capacitance, jacket zipper, etc.

silicone chips get fried in millions of a second.

RE: ERROR CODE MEANINGS/ FIXES??
 

-i took the new starter out and hooked it up to my dads tester( i didnt know he had a machine to tast starters-just like the one at advance) and the starter was bad... good voltage going to it (the purple wire).....
-the engine isnot loked up ....
-im gonna take it back and hope they'll give me a newstarter (make them test it there too before taking it home).....
- ill report back when i install it....

RE: ERROR CODE MEANINGS/ FIXES??
 

i took the starter back... they tested the new one before they gave it to me....it was good
-but when i put it in and tryed to start my car it did the same thing??????WTF!!!!!!
-I DO NOT KNOW WHAT TO DO??????
-were else could something be going wrong?

RE: ERROR CODE MEANINGS/ FIXES??
 

DID YOU test the new one, on your tester before it went in?
Then afterwards, after it wouldnt work ?

We need to know if it went in good and then got fried!

IF you didnt test it, we wont know.

.

RE: ERROR CODE MEANINGS/ FIXES??
 

yes, he tested the new one at the store in front of me before i took it home and then i double checked it when i got home before putting it in the car and IT WAS A GOOD STARTER...
they're getting fried somehow when there in the car!!!
thats what i was trying to say before... maybe i just worded it wrong..

i checked the thick wire that runs from the battery to the starter and it appeared good....
I also checked the other wire as far as i could that plugs into the starter its GOOD...
the smaller wire that comes off the starter.. were does it lead to?...
