going with what he said also check when you first turn the ignition on if the battery light comes on at all? you could possibly have a blown bulb, or you could just throw a dmm on it and check voltage.I think this code indicates the voltage is low. I would check the connections of the battery and check the voltage at the battery. Could also indicate a bad fuse. Seems like a weird code to get with out a low voltage gauge or battery lite.
