Cadillac Repair: 92 Deville/ABS light on, wheel sensors, word history

Question
I have no scan tool to retrieve any codes that might be read,diagnosed and resolved.Say, for example,if Wheel sensors are dirty and this is the cause,if I remove and clean them,how do I clear code.Also, what is the best way to retrieve codes. Thanks,...Ray.

Answer
You can retrieve the CODES thru the climate control panel by this procedure:

1. Turn ignition key to the ON position. Do NOT start the engine.

2. On the climate control panel push and hold inward the OFF and WARMER (^) buttons for 3 seconds and release them.

3. Look at the fuel data display and you will see the codes display as LETTERS & NUMBERS followed by the word HISTORY or CURRENT.

4. The fuel display will stop and display ECM?

5. Turn OFF ignition key.

6. Tell me what codes you got and whether each code displayed the word HISTORY or CURRENT after EACH code displayed.
