Problems with my 99`Deville


Recommended Posts

Hi there, from Norway!

I have a 1999 Caddy Deville, with the following current DTC codes: P0113, P0151, P1638, B2502, B1910, C1235 a couple of those are related to charging issues, so I`ve taken the alternator out and tested it, and it works, but the car won`t charge. Can the ecm be the fall guy here?? 

Great forum, by the way!! I just found out about it, on my mission to find answers to my chargeing issue......

All the best from the high north!!

Also check the plug to the alternator.

Have misdiagnosed because of that plug. 

The wires go bad right by the plug and cause intermittent or no charge


Nice, clean, luxury= fine automobile
