Res STS Posted March 1, 2005 Report Share Posted March 1, 2005 I have code C1255, Electronic brake and traction control module (EBTCM) internal malfunction, on my 58,000 mile 98 STS after the original battery went dead and installing a new Delco battery. The service manual indicates this is expected, but I have cleared it several times via OBD, but the ABS and traction control warning lamps come back on every restart along with DIC messages: Service Steering and Service Stability System. An experienced Cadillac tech told me the EBTCM is touchy and he fairly regularly can't reset C1255 and has to replace the EBTCM after battery disconnect/reconnects. I did not do anything dumb during the battery replacement, but I'm dumbfounded to look at about a $600 repair risk if you change the battery. Yes, the cable connectors are clean -- they look like new. Anyone else have experience with this? Link to comment Share on other sites More sharing options...
