Fuel Pump Control Unit: Testing and Inspection
FUEL PUMP UNIT INSPECTION [L3]
Fuel Pump Operation Inspection
1. Connect the WDS or equivalent to the DLC-2.
2. Remove the fuel-filler cap.
3. Turn the ignition switch to the ON position.
4. Using the simulation function "FP", verify that operation sound is heard from the fuel pump when "FP" is turned from OFF to ON.
If the operation sound cannot be verified, measure the voltage at fuel pump wiring harness-side connector terminal A.
-
If as specified, inspect the following:
-
Fuel pump continuity
-
If not within the specification, inspect the following:
-
Fuel pump relay
-
Wiring harnesses and connectors between main relay-fuel pump relay-fuel pump
Standard
B+ (Ignition switch at ON)
Continuity Inspection
1. Remove the battery cover.
2. Disconnect the negative battery cable.
3. Disconnect the fuel Pump unit connector.
4. Inspect for continuity between fuel pump unit terminals B-D.
-
If there is continuity, perform the "Circuit Open/Short Inspection".
-
If there is no continuity, replace the fuel pump.
