Hello Caddy Enthusiats!!!! I would like to keep things short and simple. My question today is what part(s) should be replaced based on the DTC codes that are pulled from my car? I have a 95 DeVille Concours. The codes are as follows: P035 P036 P039 P040 S010 S011 S012 S015 S016 S017 S021 S022 S025 S027 S030 S031 S035 S037 S044 S051 S060 S061 Any input would be greatly appreciated and I would like to thank everybody in advance for their suggestions. Thanx!!!
There is no way to recover OBD codes once you have cleared them, other than to wait for the car's modules to detect the same error again. That's not a bad thing because the car is pretty quick to flag a problem when it occurs. You didn't say what the problem is that caused you to run the codes, if any, but the next time it happens, any relevant codes will be there again. The next time you drive the car, then, after you park but before you turn off the key, run the codes again. That way, any codes that were thrown during the drive will be flagged as CURRENT, and anything that was detected as a problem but then checked OK will be flagged as HISTORY. Once you turn off the key, all the codes go to HISTORY.
