Light is now on steady any time the engine is running. The following is a direct quote from the Owner's Manual pg 73: "If the charging voltage falls below 10 volts, the warning lamp comes on and the ABS is switched off." It then goes on to say "If the ABS warning lamp does not go out or comes on while driving, it indicates that the ABS has detected a malfunction and has switched off." The 2nd part makes sense. I am confused about the charging voltage statement. Vehicle has 330K miles.
