at what tempature degrees are the marks separated bye on the gauge?

Generally, once it gets to the middle you're at 196 up to 225 if I'm not mistaken. I posted something a while back how to add the digital temp readout on the cluster but editing a few perameters here and there through the computer. It's REALLY EASY. It's all done through the climate control center.

I got these directions from another Cadillac forum. I think it was caddyinfo.com... it was really late when I found this so my memory is a bit hazy...

1) Press the OFF and PASS WARMER (referred to from here as WARMER) buttons simultaneously to enter diagnostic mode.

2) Let the system read any codes it has stored. You will ultimately be presented with "PCM?". You will answer with the fan speed control button. UP = yes and DOWN = no.

3) Press DOWN until you are presented with "IPC?". On mine, it's the very next prompt. When you get to the "IPC?" prompt, press UP to enter the IPC area (Instrument Panel Cluster).

4) Press DOWN until you are presented with "IPC OVERRIDE?". Press UP to enter the override area.

5) Scroll down (with the DOWN button) until you get to Option E. Wait a second or two, and the override value will appear to the right where the TRIP ODOMETER normally reads. Yours will probably read "43". That's what mine read when I first did this.

Below are the Option E values:

- Coolant Temp message (64)
- Battery Volts message (32)
- Engine RPM message (16)
- Avg Mph message (8)
- Mph message (4)
- Fuel Used message (2)
- Inst Mpg message (1)

The stock displays (for analog E/K displays) are Battery Volts, Avg Mph, Fuel Used, and Inst Mpg, for a total value of "43".

6) Use the WARMER button to increment the value of the override. In this case, we want to add Coolant Temp, so we're going to add "64" to "43", or "107". Press the WARMER button repeatedly to increment the value from "43" to "107".

If you make a mistake, you can decrement the value by pressing the COOLER button.

7) To permanently save the new value, hold the FRONT DEFROST and the A/C buttons simultaneously until the new override value flashes once.

8) You're done. Press OFF repeatedly to "back out" of the diagnostic system. You'll probably need to press OFF 5 or 6 times to get out of the deep "menu structure" you're in now.

Now, the coolant temp (in units specified) should be one "stop" along the revolving door we call the DIC. If you are in metric units, the coolant temp will read in *C. If you are in standard units, it'll read in *F.

Good luck!

BTW: the book warns against incorrectly storing an override value to the system. It said you can permanently damage the IPC by doing this. I don't know how, and have never heard of anyone doing damage to their car, but the book says the danger exists. It says if you ever make a mistake, repeatedly press OFF to completely exit the diagnostic system and start over again.

wait wait...so we can increase it to 127 to have everything display?? thas so cool! :eek:

thanx a lot bro :thumbsup:

i just did that to my car...put it up to 127. its so kickass :D lolz. im so easily amused...:bouncy:

thanks for the info...

-mir

Hey 300HPETC...You wouldnt happen to know if this is possible with 98+ Sevilles??

MacK

Any other options? More bells and whistles!!

Thanks for the information.

i tried this on my 95 etc and now my info center just says system......can someone post their factory setting on the ipc lines in the override section so i can try to get mine working again....i've asked on a couple other topics and people seem to not know what i'm talking about...or i'm worried and impatient lol

Cadillac made some major changes for the 1996 model year. I believe your IPC values are now corrupt which is why it displays "system"

IPC Override Displays for 1992-1993 (and maybe as far as 1995)

IS00 will display "none" as no overrides are active at this point.
IS08 The "Option1" override allows the ability to change the vechile option contenf information stored in the IPC. The IPC uses this option information to determine how to operate the displays AND OTHER ELECTRONIC DEVICES!
Incorrect option content information in the IPC may cause MANY different problems. Upon selection of this override the option content information will be displayed as a number. To determine the porper OPTION 1 number, calculate the sum of the applicable numbers from the following table:
If vehicle is equipped with ADD
French/Canadian displays (Canadian Only) 128
Ride Control (All Cars) 8
-------------Export Options Deleted here-----------------------

Example: Normal North American ISO8 value is 8

If necessary, the Warmer and Cooler buttons can be used to increase or decrease the OPTION 1 number. When the correct number is reached, simultaneously press and hold the ECON and FRONT DEFROST buttons for three seconds to permanently store the correct value in the EEPROM. The display will blank momentarily and then display the newly stored number.

IS09 The "Option 2" override allows the ability to change the vehicle option content information stored in the IPC. The IPC uses this option information to determine how to operate the displays and other electronic devices. Incorrrect opiton content information in the IPC may cause MANY different problems (sound familiar to Option 1?) To determine the proper OPTION 2 number, calculate the sum of the appicable numbers from the following table:

IF VEHICLE IS EQUIPPED WITH ADD

Heated windshield (C50) 128
Enable BTSI Message (All Cars) 1 [This is the... APPLY BRAKE BEFORE...]

Normal North American vehicles, IS09 value is 1 and with heated windshield is 129

As you can see from these examples taken directly from the 1992/1993 factory manuals, the IPC values are significantly different than those for the 1996.

Bottom line, if you don't have a factory manual for your car....DO NOT OVERRIDE, STORE, CHANGE, OR DELETE ANY VALUE IN ANY COMPUTER MODULE...EVER!

my settings are as follows

ISOO =0
IS09 = 1
IS08 =8
sorry to be of so much of a pain guys just a little to much DIY....thanks for listing your info seville....gonna pick up a shop man to check my other settings of
IS45=83
IS11=43
IS10=4
IS07=043
one of these has to be the prob

i'm about to find a car lot with a 95 etc and read his ecm on a test drive ...lol

i'm about to find a car lot with a 95 etc and read his ecm on a test drive ...lol

The used car lot will work too. Good luck!

IS45 value is for vacuum flourescent dimming override. 0=Max dim 99=Max bright (range 0-99)

IS07,IS10,IS11 overrides are not discussed for the 1992/1993 Seville/Eldorado as options in the manual for the Instrument Cluster Panel section 8C1.

i thought for sure someone on this forum would own a 1995 eldo. etc
