It is a code for a actuator on the shock. Look in the FAQ Forum for "ARC" and it has what number of blinks means which actuator. It also shows you how to fix them with some WD-40 and a needle nose plier.
excellent! I will do that, I looked at the link and I hope it should fix the problem. I know my shocks are going out, they have 144K on them. SO it can not hurt to try the WD-40..I may use liquid wrench, or some PB blaster...they seem to penetrate better. Thanks again
