Check engine light On what does code mean ?
Drove my 03 with 22000 miles on it today and just got on interstate and kicked it into passing gear and check engine light came on. Checked oil pressure and antifreeze everything ok. Drove 20 miles and returned home and ran codes only new one came up is 58-SDM B0090H any ideas what to do to find out what it is. Thanks

What are the "other" codes that you have????? The code you posted above does NOT set the CEL. Perhaps you have had the same condition that tripped the CEL occur before and have been ignoring it??? There are more than 20 conditions/codes that can set the CEL. Virtually all of them are emissions related.
If you pulled the codes with the engine OFF then it is possible that the code disappeared or that it was a C with the engine running and changed to an H when you turned off the ignition.
Probably not a bad idea to CLEAR all your codes so that you know what codes are truely NEW.
To pull codes with the engine running you need to use the reset button to clear all messages in the DIC and then pull codes as normal.

P0442HC is the cause of your CEL.
P0442 = Small evaporative system leak detected
This is an emissions problem that causes the CEL to be set. Probably the most common cause for this is a bad gas cap. The sealing ring on the cap my be deteriorated or may have an excessive amount of debris on the sealing surfaces or the cap may not be tight. There are other causes for the codes being set but you might start with the gas cap.
Clearing codes does NOT correct problems. It simply erases the codes that were stored in the computer. If the problem still exists the code(s) will come back after being cleared and the CEL turned on for emissions related problem(s).
Your other RDCM and LDCM codes indicate a recent battery related event or that the battery is weak or may have loose or corroded battery connections including at the starter. Have you recently disconnected/reconnected the battery? If not you might want to have the battery load tested. Most parts stores will do that free.
The B0090 is pointing to a problem with the SIR (air bag) system. This could be a real SIR system problem or it could also be a bogus condition caused by weak or low battery.
I suggest that you have the battery fully charged and then load tested and the go from there.
