THIS IS A QUALITY BULLETIN: IF THE INVERTER GENERATOR MODULE (IGM) IS EXPOSED TO HIGH TEMPERATURES AND VIBRATION, A DIAGNOSTIC TROUBLE CODE (DTC) MAY BE SET INDICATING AN INTERNAL ISOLATION FAULT THAT WILL RENDER THE IGM INOPERABLE.THE CORRECTIVE ACTION IS TO CHECK THE VEHICLES IGM SERIAL NUMBER AGAINST THE ATTACHED “IGM HOUSING SERIAL NUMBERS” LIST. IF THE LABEL NUMBER FOR THE VEHICLES IGM IS LISTED IN THE “IGM HOUSING SERIAL NUMBER” LIST, REPLACE THE IGM. IF THE LABEL NUMBER FROM THE VEHICLES IGM IS NOT ON THE LIST, NO FURTHER ACTION IS NECESSARY.
