FUEL TRANSPORT PUMP

Specification data are reference values, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic ProcedureEBS011PG
1. CHECK OVERALL FUNCTION
1. Turn ignition switch OFF.
2. Confirm that the engine is cooled down and there are no fire hazards near the vehicle.
3. Disconnect sub fuel level sensor unit harness connector.
4. Remove sub fuel level sensor unit.
