you can disconnect the battery for a few minutes or pull the 20amp AHC fuse for a few minutes...that might work to clear the codes. Alternatively, use a code reader from any parts store to erase the codes. If they are current concerns, the codes will reappear shortly.

Check here for a similar condition that arose due to an electrical short.

AHC bumpy and rough ride

Hi Guys, I literally "hit the wall" in terms of trying to find out what's wrong with the ride quality, it was never velvet like but WAY better than in the recent months. I am dealing with 06 LX with 104K miles, and the codes I get are DTC 1721 and 1723 which translates to front and rear...

At the bottom of the screen in TechStream there's an eraser symbol which you use to remove codes. Also, there are columns which show if the codes are active or historic.

For reading pressures, you can do it only after moving the ahc height from N to Lo and back to N.
You really have to read the Definitive ahc thread. Most questions are answered there.
