ISSUE: Electronic control modules, including EEC processors, may be damaged if the negative battery ground cable is not disconnected before arc welding is performed. This occurs because the arc welding process can produce high electrical currents in the body of a vehicle when the negative battery ground cable is left connected.
ACTION: If arc welding procedures are to be performed, be sure to disconnect the battery ground cable.
CAUTION: DISCONNECT THE NEGATIVE BATTERY GROUND CABLE BEFORE USING ANY ELECTRIC WELDING EQUIPMENT.
