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)
Transmission Fluid Temperature Sensor "A"
DESCRIPTION
The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid
temperature into a
resistance value which is input into the ECM.
The ECM applies a voltage to the temperature sensor through ECM terminal THO1.
The sensor resistance changes with the transmission f ...

Back Door Closer Switch Malfunction
DTC B2215 Back Door Closer Switch Malfunction
DESCRIPTION
This DTC is output when a malfunction occurs in the position switch in the
back door. This position switch
detects if the back door is in the latch position and sends a position signal to
the power back door ECU.
DTC No.
