My '95 turbo wagon's dash was starting to look like a Christmas tree: check engine, service, and SRS lights. I reset the service light no problem, as per the Haynes manual. But I have some questions about the others, and Haynes doesn't give codes for the SRS (B5) or Auto Trans (A1)

1. Socket B5 (SRS) read a fault code of 222. What is this? I reset the system and the light went out OK. The light came on after recent torrential rains, so I wonder if a contact somewhere got wet. If the light does not come back on is the system OK and functional?

2. Socket A6 (Ignition) gave no code (not even the 111). Resetting it did turn off the check engine light (after doing #3 below).

3. One evening my shift light flashed on and off a few times, and after this the check engine light came on. I checked socket A1 (auto trans) and got 2 fault codes: 313 and 114. A search of prior posts says this means the gear position sensor and the sport-economy switch, respectively. I reset the system and everything seems to be working fine.

Should I worry, or just drive the thing and wait to see if the warnings return?
Is there a master code list somewhere?

Thanks,
Nick
