I just acquired this vehicle from an estate sale from the original elderly owner.
Car is in great shape.
I do not however, like the computer readout. According to the owner's manual, all components are checked by the computer at startup and it will post a message of any problems.
With the digital dash, you have only a fuel gauge and speedometer, nothing else.
On an older Caddy that I had, if you pressed the information button, it would walk you through all of the steps, mpg, etc and then it would allow you to toggle through the coolant temp, oil pressure, voltage, etc.
Is there a way for the computer in this 1994 to do that?
Or should this be doing that already.
I am not familiar with this computer so any information would be helpful. I just don't want to trust my important information to and idiot light.
Thanks

Hi cp4022, Welcome to 2carpros and TY for the donation

According to Mit1 when reviewing the Instrument Panel its the same as your older Caddy On the DIC to read out misc.such as below:

DRIVER INFORMATION CENTER
Driver Information Center (DIC) is 20-character dot matrix display area in the bottom center portion of cluster. See Fig. 1 and Fig. 2 . The DIC is used to display warning/status messages and driver selectable information.
INFORMATION Button
Pressing the INFORMATION button begins DIC displays for Engine RPM, Coolant Temperature, Battery Voltage, Oil Life Index, Fuel Used and all monitored systems status/warning messages.
DISPLAY ON/OFF Button
Pressing DISPLAY ON/OFF button turns off illuminated displays except for speedometer, turn signals, and cruise engaged indicator. All systems continue working, but are not visible to driver. Press button again to resume illumination of all displays.
Oil Life Index
Pressing INFORMATION button will cycle messages until "Oil Life Index" is displayed. The numbers displayed represent the percentage of useful oil life remaining. When oil life reaches zero percent, the message CHANGE ENGINE OIL will display. After an oil change, reset display by pressing INFORMATION button until "Oil Life Index" is displayed, and then press and hold STORE/RECALL button for about 5 seconds. When properly reset, 100 percent will display.
STORE/RECALL Button
Pressing this button allows driver to acknowledge message(s) on DIC display and store it in IPC memory. All stored messages during an ignition cycle can be reviewed one at a time by pressing Store/Recall Button. Messages are erased by pressing Display On/Off button or by turning off ignition.

I tried using the information button and all that I can get to display is avg. Mph, avg. Mpg, timer, oil life, gals of fuel used, etc but nothing about the engine itself.

Could this be a malfunction in the computer or is there a way to display this information be overriding one of the values, like overriding the ride control, etc.

If anybody can explain this to me, I would greatly appreciate it. I have checked the owner's manual and all it says is that if the car is not for Canada that all of the functions are monitored and are only shown if there is a problem, which I think is stupid. You can save a car sometimes before the damage is done if you can see it happening before it actually happens, duh.

This all I got for you on the driver's information center as stated in the instrument panel cluster. Dunno if its just pops up when it senses problem-I know exactly what you're trying to say-Early warning-Sorry! Not that much help
