INSPECTION PROCEDURE
1 Check CIG and ECU±IG fuses.
PREPARATION:
(a) Remove the fuse box opening cover.
(b) Remove ECU±IG fuses from instrument panel junction
block No.1.
CHECK:
Check continuity of ECU±IG fuses.
OK:
Continuity
NG Check for short in all the harness and compo-
nents connected to the ECU±IG fuses (See at-
tached wiring diagram).
OK
2 Check voltage between terminal IG of theft deterrent ECU and body ground.
PREPARATION:
(a) Disconnect the theft deterrent ECU connectors.
(b) Turn ignition switch ON.
CHECK:
Measure voltage between terminal IG of theft deterrent ECU
connector and body ground.
OK:
Voltage: 10 ± 14 V
NG Check and repair harness and connector be-
tween theft deterrent ECU and battery
(See page IN±31).
OK
Check and replace theft deterrent ECU.

(g) When necessary, use a sealer on gaskets to prevent
leaks.
(h) Carefully observe all specifications for bolt tightening
torques. Always use a torque wrench.
(i) Use of special service tools (SST) and special service ma-
terials (SSM) may be required, depending on the nature
of the repair. Be sure to use SST and SSM where speci-
fied and follow the proper work procedure. A list of SST
and SSM can be found in Preparation section in this
manual.
(j) When replacing fuses, be sure the new fuse has the cor-
rect amperage rating. DO NOT exceed the rating or use
one with a lower rating.

ON±VEHICLE INSPECTION
1. CHECK FUEL PUMP OPERATION
(a) Connect a TOYOTA hand±held tester to the DLC3.
(b) Turn the ignition switch ON and push the TOYOTA hand±
held tester main switch ON.
NOTICE:
Do not start the engine.
(c) Select the ACTIVE TEST mode on the TOYOTA hand±
held tester.
(d) Please refer to the TOYOTA hand±held tester operator's
manual for further details.
(e) If you have no TOYOTA hand±held tester, connect the
positive (+) and negative (±) leads from the battery to the
fuel pump connector. (See step 7)
(f) Check that there is pressure in the fuel inlet hose from the
fuel filter.
HINT:
If there is fuel pressure, you will hear the sound of fuel flowing.
If there is no pressure, check the fusible link, fuses, EFI main
relay, fuel pump, ECM and wiring connections.
(g) Turn the ignition switch OFF.
(h) Disconnect the TOYOTA hand±held tester from the
DLC3.
2. CHECK FUEL PRESSURE
(a) Check the battery positive voltage is above 12 V.
(b) Disconnect the negative (±) terminal cable from the bat-
tery.
(c) Remove the union bolt and 2 gaskets, and disconnect the
fuel inlet hose from the fuel filter outlet.
CAUTION:

Put a shop towel under the fuel filter.

Slowly loosen the union bolt.

The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.
