5. Partially uncover the carpet.
6. Remove cover of service hole.
7. Release connector of fuel pump assy.
8. Inspect continuity between terminals B and D
of fuel pump connector.
l If the continuity is good but the Simulation
Test is failed, inspect for Circuit Open/Short.
l If open, replace the fuel pump body.
Open/Short Circuit Inspection
1. Inspect for an open or short circuit in the
following wiring harnesses.
l If there is open or short circuit, repair or
replace wiring harnesses.
Open circuit
l GND circuit (between connector D of fuel
pump and vehicle body GND)
l Power circuit (fuel pump relay connector
terminal E and fuel pump assembly
connector terminal B through common
connector)
Fuel Pump Relay
Short Circuit
A. Circuit between fuel pump assembly
connector B and terminal E between
connectors of fuel pump relay, through
common connectors is short circuit to
ground (GND).
2. Reconnect the fuel pump assembly connector.
3. Install cover of service hole.
4. Refit carpet.
5. Install second-row seat. (Refer to Second-Row
Seat Removal/ Installation)
