DESCRIPTION
This causes current to flow through the fuel pump resistor to the fuel pump. The fuel pump then operates at low speed. The FUEL PUMP relay is turned OFF while the engine is cranking or operating at high load. The fuel pump then operates at normal speed.
WIRING DIAGRAM
This troubleshooting procedure is based on the premise that the engine is started. If the engine is not started, proceed to the problem symptoms table (See page ES-27).
INSPECTION PROCEDURE
1 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the intelligent tester ON.
(c) Enter the following menus: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / FUEL PUMP SP CTL.
(d) Check the operation of the relay while operating it using the intelligent tester.
OK: Operating noise can be heard from the relay.
2 INSPECT RELAY (FUEL PUMP RELAY)
(a) Remove the FUEL PUMP relay from the engine room junction block.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
(c) Reinstall the FUEL PUMP relay.
3 CHECK HARNESS AND CONNECTOR (FUEL PUMP RELAY - ECM)
(a) Remove the FUEL PUMP relay from the engine room junction block.
(b) Disconnect the E11 ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance
(d) Reconnect the ECM connector.
(e) Reinstall the FUEL PUMP relay
REPLACE ECM (See page ES-498)

1. CHECK DLC3
The vehicle's ECU uses ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format
