Fuel Pump Control Circuit
CIRCUIT DESCRIPTION
In the diagram below, when the engine is cranked, current flows from terminal ST of the ignition switch to
the starter relay coil and also current flows to terminal STA of ECM (STA signal).
When the STA signal and NE signal are input to the ECM, Tr is turned ON, current flows to coil of the circuit
opening relay, the relay switches on, power is supplied to the fuel pump and the fuel pump operates.
While the NE signal is generated (engine running), the ECM keeps Tr ON (circuit opening relay ON) and the
fuel pump also keeps operating.

(5) See page DI−138 to confirm the details of the
DTCs.
NOTICE:
When simulating symptoms with an OBD II scan tool (ex-
cluding TOYOTA hand−held tester) to check the DTCs, use
the normal mode. For codes on the DTC chart subject to ”2
trip detection logic”, turn the ignition switch off after the
symptoms have been simulated for the first time. Then re-
peat the simulation process again. When the program has
been simulated twice, the MIL lights up and the DTCs are
recorded in the ECM.
3. Check Mode:
INSPECT DIAGNOSIS
HINT:
TOYOTA hand−held tester only:
Compared to the normal mode, the check mode has high sens-
ing ability to detect malfunctions.
Furthermore, the same diagnostic items which are detected in
the normal mode can also be detected in the check mode.
(a) Check the DTC.
(1) Initial conditions.
Battery positive voltage 11 V or more
Throttle valve fully closed
Transaxle in the PARK position
Air conditioning switched off
(2) Prepare the TOYOTA hand−held tester.
(3) Connect the TOYOTA hand−held tester to the
DLC3.
(4) Turn the ignition switch ON and switch the TOYOTA
hand−held tester ON.
(5) Switch the TOYOTA hand−held tester from the nor-
mal mode to the check mode (Check that the MIL
flashes.).
(6) Start the engine (The MIL goes off after the engine
start.).
(7) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTCs, etc.
(8) After simulating the malfunction conditions, use the
TOYOTA hand−held tester diagnosis selector to
check the DTCs and freezed frame data, etc.
HINT:
Take care not to turn the ignition switch OFF.
Turning the ignition switch off switches the diagnosis system
from check mode to normal mode, so all DTCs, etc. are erased.
(9) After checking the DTC, inspect the applicable cir-
cuit.

(b) Clear the DTC.
The following actions will erase the DTCs and
freezed frame data.
Operating the OBDII scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes (See the TOYOTA hand−held tester or OBD
II scan tool’s instruction book for operating instruc-
tions.).
NOTICE:
If the TOYOTA hand−held tester switches the ECM from the
normal mode to the check mode or vice−versa, or if the
ignition switch is turned from ON to ACC or OFF during the
check mode, the DTCs and freezed frame data will be
erased.
(c) Inspect the DLC3.
The vehicle’s ECM uses V.P.W. (Variable Pulse Width) for
communication to comply with SAE J1850. The terminal
arrangement of DLC3 complies with SAE J1962 and
matches the V.P.W. format.
Terminal No.Connection/Voltage or ResistanceCondition
2Bus Line/Pulse generationDuring communication
4Chassis Ground − Body/1 Ω or lessAlways
5Signal Ground − Body/1 Ω or lessAlways
16Battery Positive − Body/9 − 14 V or 1 Ω or lessAlways
HINT:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of the OBD II scan tool or
TOYOTA hand−held tester to the DLC3, turned the ignition
switch ON and operated the scan tool, there is a problem on the
vehicle side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool’s instruction manual.

DTC P0750, P0755 Shift Solenoid A/B Malfunction
(Shift Solenoid Valve No. 1 / No. 2)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd or O/D
gear). The ECM then compares the actual gear with the shift schedule in the ECM memory to detect mechan-
ical trouble of the shift solenoid valves and valve body.
DTC No.DTC Detecting ConditionTrouble Area
P0750
P0755During normal driving, the gear required by the ECM does not
match the actual gear (2 trip detection logic)Shift solenoid valve No. 1 / No. 2 is stuck open or closed
Valve body is blocked up or stuck
HINT:
Check the shift solenoid valve No. 1 when DTC P0750 is output and check shift solenoid valve No. 2 when
DTC P0755 is output.
INSPECTION PROCEDURE
1 Check shift solenoid valve No. 1 or No. 2 operation.
PREPARATION:
(a) Remove the oil pan.
(b) Remove the shift solenoid valve No. 1 or No. 2.
CHECK:
(a) Applying 490 kPa (5 kgf/cm2, 71 psi) of compressed air,
check that the shift solenoid valves do not leak air.
(b) When battery positive voltage is supplied to the shift sole-
noid valves, check they open.
NG Replace shift solenoid valve No. 1 or No. 2.
OK
2 Check valve body (See page DI−141).
NG Repair or replace valve body.
OK
Repair transaxle (See page AX−15).

DTC P0770 Shift Solenoid E Malfunction
(Shift Solenoid Valve SL)
SYSTEM DESCRIPTION
The ECM uses signals from the throttle position sensor, air−flow
meter and crankshaft position sensor to monitor the engage-
ment condition of the lock−up clutch.
Then the ECM compares the engagement condition of the
lock−up clutch with the lock−up schedule in the ECM memory
to detect mechanical trouble of the shift solenoid valve SL,
valve body and torque converter clutch.
