Cadillac Repair/ABS-Traction Control - clearing light

Question
Rob, on my 2004 Cadillac SLS I have a C1232 front left wheel sensor code.  Obviously this is flagged on my dash - "ABS-Traction Control" lights are illuminated.  Ok, so I have cleaned the sensor and checked the connections - but my issue is I CANNOT CLEAR THE ABS-Traction control lights manually with my scanner or from the dash control that Cadillac offers.  On my scanner and on the dash control is asks -- Clear codes?  I answer Yes - the chime on the dashboard goes off, but the light remains illuminated and after rechecking with scanner or from the dash control the 1232 code remains.  I understand the the fault-problem may still remain, but my problem is simply resetting all the codes and running the car for a new readout.  Is there something peculiar to ABS-Traction control light clearing manually?  As always, thanks for your expert input - Respectfully - Steve B

Answer
Hi,

You have what is known as a hard code. There is steal something wrong that you may have missed keeping that warning light on.
The problem could be anywhere. Another sensor, the abs, the computer. It is so hard to say without being at the car and the correct diagnostic equipment (tech II).
The cheapest and easiest way (don't go to a dealer) is find a repair garage that has a tech II and get the problem correctly diagnosed. Might cost you $50, but you will know what exactly is wrong.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
