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

[CadillacSTS2003]

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
ALSO I AM NOT RESPONCIBLE FOR ANYONE WHO SCREWS UP AND DOES NOT FOLLOW DIRECTIONS!!!!

~~~~~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

Put it in th Tech Tips section.

[CadillacSTS2003]

i wasnt sure if itd be a HERE thing or in the tips section
im bad at this location thingy

[urbanski]

i copied to tech tips

[CadillacSTS2003]

ahh
that explains i was like
how it get there so fast!

[iametarq]

now if only someone could get this to work for the 98+ Seville that would be "money".

[CadillacSTS2003]

you can
follow same steps with modifiy
only you need a tech 2!!!

[stevebuick23]

I did them. Worked great, except I couldn't get the engine RPM one to work. That one would have been handy as well.

[CadillacSTS2003]

RPM is non functional
the reason you can get the coolant and MPH message is b.c of the digital dash used in devilles
b.c the rpm wire is hooked up to the tach instead the the dic it will not display
digital dashes have no tach so they rely on the dic to display it

[stevebuick23]

Ah, ok, thought I was doing something wrong.

[iametarq]

So if my dealer can do this with a Tech II tool, where did you find this to do it? Is it printed in the 98+ FSM somewhere? I think the only way I can get them to do it is if i prove they already "know" how to do it, they just need to look it up.

[Mccalist]

Tell Them To Look Under "ipc."

[CadillacSTS2003]

yup
youd use the Tech 2 as if it was the controler for the DIC to display those things
im pretty sure as you control the things via the tech 2 the DIC will show the changes as you do them in the Tech 2

For the 2003 STS, simply pull the DRL fuse located in the engine compartment fuse block.

[CadillacSTS2003]

you also lose highbeams ive herd with that
