Tampa Caddy Posted December 14, 2006 Report Share Posted December 14, 2006 Just replaced all pads and had to pull the Pass rear caliper and bleed the brakes. Now the Anti lock and Traction lamp is on I went into Diag mode Tcs Dtc shows 1234, 1233 & 1255. I heard you need to reset the codes after brake work but after pressing the off key on each code it will not reset. There are other History codes that will not reset, I assume I'm doing something wrong. One Question could the ware sensor on the pads be installed wrong? Any help would be "well helpfull" on how to clear these codes before my wife kills me for braking her Caddy! Link to comment Share on other sites More sharing options...
Cadillac Jim Posted December 14, 2006 Report Share Posted December 14, 2006 C1233 Right Front Wheel Speed Circuit Open or Shorted C1234 Left Rear Wheel Speed Circuit Open or Shorted C1255 EBCM Internal Malfunction It looks like the wheel speed sensors are unplugged on the right front and left rear. The wheel speed sensors are on the center of the hub on the inside. It's common to knock a couple of these loose when doing brake work. You can clear the codes by disconnecting the negative cable of the battery for about 30 seconds. You will see a P0603 or some such that complains that the codes were reset, but it won't disable anything and will go away with time. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

Ranger Posted December 14, 2006 Report Share Posted December 14, 2006 After the DTC's have been displayed, use the HIGH FAn to answer YES and the LOW FAN to answer NO to the prompts till you see CLEAR CODES? Link to comment Share on other sites More sharing options...

Ranger Posted December 15, 2006 Report Share Posted December 15, 2006 That's usually the case when it happens after a brake job. Link to comment Share on other sites More sharing options...
