FUEL PUMP/LEVEL UNIT MODULE For vehicles with Saddle Fuel Tanks, need to determine if there are any DTCs in wiTECH. Follow Service Diagnostics published prior to making any changes. Review any existing SOL or TSBs published for customer complaint issue. Only the Fuel Pump Module should be replaced if there are DTCs associated with the Fuel Level Sensor number 1. Only the Auxiliary Level Sender should be replaced if there are DTCs associated with the Fuel Level Sensor number 2. If there is a mixture of DTCs between the Fuel Pump Module and the Auxiliary Level Sensor, then investigate if there is a Jumper Harness or circuit issue between the Level Sender and the PCM. Verify fuel transfer between auxiliary tank and the primary tank by monitoring the auxiliary level sensor to verify it drops after driving.
