Crazyfurie Posted October 3, 2010 Report Share Posted October 3, 2010 I need some help, I've been having the Traction control light staying on, and the ABS light coming on and off every so often, it annoyed me to the point of where i decided to reset the codes and took about a 200mile ride over about 3days. and i got the new codes and their description, the ones that showed up as "current" are labeled with current near them, the rest came up as history but they obv arent exactly history if i got them again XD MSM - B1860 - Driver Lumbar Vert Sensor Circuit Malfunction SDM - B1163 - Loss of Serial Data-No Lamp Response U1040 - Loss of Class 2 Communications with ABS U1255 - Class 2 Communication Malfunction (Serial Data Line Malfunction) PCM - P1520 - Transmission Range Switch Circuit *current* P1571 - Traction Control Torque Request Circuit *current* P1602 - Knock Sensor (KS) Module Performance IRC - U1144 - Loss of Communications with PHN IPM - U1066 - Loss of Communications with RIM IPC - U1301 - Class 2 Short to Battery DIM - U1066 - Loss of Communications with RIM AMP - U1064 - Loss of Communications with DIM U1128 - Loss of Communications with IRC ABS - C1236 - Low System Supply Voltage C1277 - Requested Torque Signal Circuit Malfunction *current* U1056 - Loss of Communications with RSS U1016 - Loss of Class 2 Communication with VCM also, alot of times when im going up a steep incline and put my foot on the peddle harder, my music will turn off and at times a "beep" will sound after the music turns off along with the ABS light flashing on for a moment then shutting off, then my music will come back on. the engine its self sounds amazing in my opinion. starts up in the first 1-2 seconds of turning the key in the ignition. Thank you to anyone that can offer help Link to comment Share on other sites More sharing options...
Texas Jim Posted October 3, 2010 Report Share Posted October 3, 2010 Take off the battery cables (BOTH OF THEM) and clean them "GOOD" The Red one is more than one piece...separate it and clean all of the pieces. A lot of your codes are loss of communication...that "MAY" be caused by nothing more than dirty or loose battery cable. Link to comment Share on other sites More sharing options...
Crazyfurie Posted October 4, 2010 Author Report Share Posted October 4, 2010 I made an apointment for my mechanic to take alook at everything, ill be sure to tell him "could it possible that the battery cables could be dirty? or the abs sensor be dirty?"

BodybyFisher Posted October 4, 2010 Report Share Posted October 4, 2010 That is what Jim was saying, your connections could be dirty, especially the positive cable they need cleaning and tightening, Take the connections apart, thank the red insulator off and clean them with battery terminal cleaner and a wire brush, any white acid/corrosion needs to go Then check the battery, have it load tested Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
