SOURCE: what are these codes for 92 cadillac deville

Hello williamcole7: My name is Roger and I will help you. The code 888 is a test code. This tests the L e d's of the dash cluster. All segments must light so you can read all numbers. The 70 code means the system is ready and able to function. The ff code is a current BCM code and is happening at the moment. The f 40 code is a BCM history code and means it was a stored problem or something that has happened. The f 40 code is for a air mix door problem. THe BCM would set this if you had an A/C problem. The E 48 code deals with the EGR system fault. I would check for a vacuum leak at the EGR solenoid. The hose is prone to deterioration do to heat from the engine. Code E52 deal with loss of voltage. A dead battery or a disconnected battery cable will always set this code. None of these codes will keep the car from running.The repair schematics are to extensive to send in a reply. Should you need further help ao assistance I will be glad to help. Please rate the answer. Thank You for using Fix Ya. Roger

SOURCE: what does an e48 code mean on 1990 cadillac

Below os a description of what code e48 is and basically has to do with the EGR system and your computer doing tests and the tests failing. As far as the other codes I'm not certain to be honest with you. I do know by holding the "OFF" & "LOW" buttons at the same time clears the codes in the BCM and a 7.0 should appear at the end. The .0.7 and the .8.8.8 I am sorry but didn't have any luck with that and really haven't heard of. Wish I could be more help but here is the description on the e48 for you. Hope this helps.

E48 - EGR System Problem 91 cadillac deville


EGR systems are prone to trouble, because it recirculates exhaust gases back into the manifold, the EGR valve gums up with carbon from the exhaust gases, if it is the type you can remove, remove the valve it generally can be cleaned with carb cleaner and replaced.

Show engine error codes on display 2006 Cadillac CTS


Unfortunately not. This vehicle has a very sophisticated CPU and the old age tricks will not work on this particular design. You will need to gain access and allow a professional GM tech to pull the Cadillac codes. An ordinary code reader may miss the exclusive Cadillac codes that may be stored at any given time.

A certified GM/Cadillac code reader will be your best bet..
