Basically ignore that code unless it occurs with lots of other codes. If you see it with lots of other codes it's an indication your battery terminals may be lose or corroded. -- -- DougW -- 93 ZJ 4.0 http://members.cox.net/wilsond HESCO Supercharger - 300W IASCA Stereo - Edelbrock IAS Shocks Gibson Exhaust - rear DCpower - custom gauge install - Stillen Rotors Banks Header - and BEER, in the fridge! |

The light went off today, only to come back on later on in the day. Tomorrow I have to clean the terminals! Jason |
