It does not appear that you are extracting DTC codes, you are reading real time data

Go to the top of this page, click HOW TO, then DTC codes, and then follow the directions on how to extract the codes for your year

thx BodybyFisher... but I want to know what is kind of data that I read ...plz

I am not sure what you are saying, but..... When you follow the directions that I referred you to, IF there are codes the diagnostic system WILL present them to you, write them down as they are presented and post them here

if you can't keep up, extract the codes again

You need a FSM to tell you what all that data is and what the parameters are for each. They are things like RPM, engine temp, MAP (manifold absolute pressure), O2 sensor counts, injector pulse width etc.

IN 1992 the DTC codes looked like this: http://www.caddyinfo.com/stscodes.html

EO12 No Distributor Signal

EO13 Right Oxygen Sensor Not Ready

EO14 Shorted Coolant Temp Sensor

EO15 Open Coolant Temp Sensor Signal

Here goes, I found my 92 manual and this is what your PCM data codes mean and the normal range:

P.2.5 - PROM I.D. - 0 to 999 CODE

P.2.4 - Ignition cycles - 0 to 255 KEY CYCLES

P.2.3 - PRNDL (CKT 771, 776) - 00 TO 11 (0=SW. CLOSED)

P.2.2 - PRNDL (CKT 772, 773) - 00 TO 11 (0=SW. CLOSED)

P.2.1 - CRUISE SERVO POSITION - 0 TO 100 PERCENT

P.2.0 - BLOCK LEARN - 0 TO 255 COUNTS

P.1.8 - FUEL INTEGRATER - 0 TO 255 COUNTS

P.1.6 - O2 CROSS COUNTS - 0 TO 255 COUNTS/SECOND

P.1.4 - O2 SENSOR VOLTAGE - 0 TO .99 VOLTS

P.1.2 - INJECTOR PULSE WIDTH - 0 TO 99.6 MILLISECONDS

P.0.9 - VEHICLE SPEED - 0 TO 255 MPH

P.0.8 - ENGINE SPEED - 0 TO 637 RPM/10

P.0.7 - BATTERY VOLTAGE - 0 TO 25 VOLTS

P.0.6 - SPARK ADVANCE - 0 TO 90 DEGREES

P.0.5 - IAT - -40 TO 151 DEGREES C

P.0.4 - COOLANT TEMPERATURE - -40 TO 151 DEGREES C

P.0.3 - COMPUTED BARO - 60 TO 102 KPA

P.0.2 - MAP - 14 TO 109 KPA

P.0.1 - THROTTLE POSITION - -10.0 TO 90.0 DEGREES

This should give you what you need. Everything look like it is within the ranges shown.

Thanks Paul for the info.

I directed this member toward trouble codes because of what he said in this initial posting

"I checked the computer and the following trouble codes came up"

As you, I saw these as real time data from my experience with my 91, not trouble codes

Thanks

Sorry ...BodybyFisher....I bought this car last week.. and I didn't know how to get trouble codes

Simultaneously press and hold the OFF and WARMER buttons on the climate control panel. I believe the codes will be displayed on the fuel data center. When you see .7.0, the system is waiting for input. You can press AUTO to exit the diagnostics or just turn the key off.

Sorry ...BodybyFisher....I bought this car last week.. and I didn't know how to get trouble codes & diagnostic data

so plz forgive my mistake.......

and thank you guys for your help

Oh nothing to be sorry about at all, we were attempting to direct you as to how to extract the DTC codes. Your action was not a mistake at all, as a matter of fact, I was quite impressed as to how far you DID get. Please be careful, OBD1 systems can be overridden. KHE posted some info for you that should be helpful.

I wish I could find my 91 Diagnostic manual, it would be helpful to you, Ill do a search here to see if I can find what I posted in the past

Welcome aboard

thanks...BodybyFisher.. I would be thankful....for any information about my DeVille 1992.

We used to have access to the owners manuals in PDF form, it was nice to be able to quickly search through them but we cant get to them anymore.

See this site for Cadillac History, it will give some info on your 1992
