How to Check Car Codes in Cadillac Cars

by Katebo

You can check the car trouble codes for your Cadillac without the use of any special tools. The Cadillac is relatively unique in that it allows you to retrieve the trouble codes right from the driver's information center on the driver's-side instrument panel. These trouble codes can be looked up in the Cadillac's owner's manual to obtain their exact diagnostic meaning.

Put the key into the ignition and turn it to the "on" position.

Locate the Driver's Information Center labeled on the control panel. Press in and hold the "On/Off" button simultaneously with the up arrow for five seconds.

Let go of the buttons when you see text appear on the Driver's Information Center.

Press the up or down arrow buttons to scroll through the trouble codes. Write the codes on a piece of paper and look up their meanings in the Cadillac's owner's manual.

Turn off the ignition and have the vehicle serviced or repaired based on the diagnostic information obtained from the codes.
