Tip & How-To about 1993 Cadillac DeVille


I constantly read frequent requests for RADIO CODES referring to the disconnection of battery power ( whether its for changing the battery, etc.) and the radio is now INOP. Here is a simple way to save radio codes, radio stations, clock time and computer settings. Purchase from an auto parts dealer, a 9 volt battery powered lighter socket connector. Plug into lighter, do your battery work, After work is completed, disconnect, and radio will work as before. Unit will cost less than 20.00 and well worth it.

After I change my battery give me all this codes ,u1403,u0141,u1120,u1103,u110e

All the codes you have listed are all Network Communications Codes....Possible Computer Failure..All codes are for different control modules at fault...Body control modules,drive motor control modules.Power control modules...,etc....Did you touch anything that caused sparks..?..Was lights,radio,..etc..turned on when battery was replaced..? You can try disconnecting battery completely..Then reconnect...USE SAFETY GLASSES..They could all be false codes if you are lucky...The computer will reset itself doing this...Be positive ALL components are OFF before doing this.....If all is the same codes take it to dealer and they will use proper scanner...
