This is general info, since not much out there on this one. My very high mileage 04 XC90 (322K miles) popped the SRS light and my new ISoft tool will erase this SRS 0211 code but it comes back on in 4 seconds. I've worn out the keyboard and web looking for answers to "right front impact sensor not communicating". Finally found the sensor(s) right under the headlight assembly, and swapped them to verify a bad sensor (hope hope). No such luck, not only was i able to verify the system was actually working, but also that both sensors were fine. Yuck. One last stab at eyeballing it, and I see the wire from the right front sensor is broken away from the harness upstream, in a most difficult location. This may be a body shop situation. Wanted to post in case anyone else is searching on that error code and can't find any information. The system actually works, and I figure the high miles and Texas heat over the years has just baked that part of the harness.
