    How to Shut off DRLs (and add digital coolant temp and speedo in the dic)

    Mods Please STICKY!!!!
    NOTES
    THIS ONLY WORKS FOR THE FOLLOWING MODELS!!!
    96-02 Eldorado, ETC, ESC
    96-97 Seville, STS, SLS
    96-99 Deville, Concourse, DeElegance

    ~~~~~TO ADD COOLANT AND MPH DIC MESSAGE~~~~~
    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.




    ~~~~~TO SHUT OFF DRLS~~~~~

    1-4 FOLLOW ABOVE DIRECTIONS!!!

    5) Scroll down (with the DOWN button) until you get to Option C. Wait a second or two, and the override value will appear to the right where the TRIP ODOMETER normally reads.

    Below are the Option C values:

    IPS03 Option C
    - RSS installed (128)
    -Premium Unleaded Fuel Only -
    -Graphic supression (digital) (64)
    -Daytime running lamps enabled (32)
    -Cellular Telephone Installed (16)
    -BTSI message suppression (4)
    -Options not set (2)
    -FUEL LEVEL LOW message suppresion (1)


    6) Use the COOLER button to decrease the value of the override. In this case, we want to remove the DRLs so subtract your number by 32

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

    NOTE!!!!
    in order for your drls to ACTUALLY BE OFF your twilight must be pushed all the way to the left and your fog lights (when applicable) must be off as well!!!

    HOPE THIS HELPS

    Re: How to Shut off DRLs (and add digital coolant temp and speedo in the dic)

    I used the procedure to get the digital speedometer and coolant temp for a '97 SLS...it worked fine. I wonder why Cadillac didn't include those options in the factory setup?? I prolly won't ever use the speedometer feature, but I really like knowing exactly what temp the coolant is at. Nice post.

    it wasnt really supposed to be for the Eldo and Seville
    this was on the Deville which had a digital speedo and no coolant gauge
    Its cheaper and easier to use the same programming and adjust it so they had those features on for the Deville by default and off on the Eldo and Seville

    I used the procedure to get the Shut off DRLS and it works fine. My problem is now I'm getting a message saying; "option not set."

    Thank you.

    its much better to just remove the drl fuse when you set the ips to disable the drl's you loose the automatic headlight and twilight sentenel feature.
    on my 97 deville it was under the hood. its a red one what ever amp that is.

    I mentioned this before, but since this is more frequently visited than the other thread, I'll alos put the pics here. I have a 1998 Eldorado Touring Coupe, which did not originally come with a digital speedo or coolant temp gauge. Using the procedures outlined here, I got them both. Was going for the Tach too, but decided I would never need it.





    Both work exactly as they should while driving, and it is really cool to see the exact temperature of the engine. The Speedo is obviously redundant, but I do like setting the cruise control a little high, so this let's me get exactly the margin over the speed limit that I'm looking for.

    Re: How to Shut off DRLs (and add digital coolant temp and speedo in the dic)

    I'm having a small problem with this.

    1996 Deville doesn't seem to have a button labeled A/C in the panel. I've tried pressing Front Defrost in together with various other buttons with no luck.

    Exactly which two buttons should I be pressing together to save the new override value?

    I figured out the answer to my own question.

    The two buttons that need to be held in are the "front defrost" (NOT "defog") and the "AUTO/ECON" button.

    They need to be held together for at least five seconds. Be sure not to release them until that number in the trip meter flashes.
