HINT:
Check the indicator as shown in illustration.
4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
(b) Check the fusible link and fuses for continuity.
5. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
If any defect has been found, replace the drive belt.
HINT:
Cracks on the rib side of a belt are considered acceptable. If the
belt has chunks missing from the ribs, it should be replaced.
(b) Using a belt tension gauge, measure the drive belt ten-
sion.
Belt tension gauge:
DENSO BTG-20 (95506-00020)
Borroughs No. BT-33-73F
Drive belt tension:
New belt175 ± 5 lbf
Used belt115 ± 20 lbf
If the belt tension is not as specified, adjust it.
HINT:

ºNew beltº refers to a belt which has been used less than
5 minutes on a running engine.

ºUsed beltº refers to a belt which has been used on a run-
ning engine for 5 minutes or more.

After installing a belt, check that it fits properly in the
ribbed grooves.

Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.

INSPECTION PROCEDURE
1 Check voltage between terminals +B (A7 - 17, 18) and GND (A7 - 16, 19) of ABS
actuator connector.
PREPARATION:
Disconnect the connector from the ABS actuator.
CHECK:
Measure the voltage between terminals A7 - 17, 18 and A7 -
16, 19 of ABS actuator harness side connector.
OK:
Voltage: 10 - 14 V
NG Check and replace fuses.
Check and repair harness or connector.
OK
If the same code is still output after the DTC is deleted, check the contact condition of each con-
nection. If the connections are normal, the ECU may be defective.

(3) Precoated parts are indicated in the component il-
lustrations by the º
º symbol.
(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.

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 these parts:

Fusible link

Fuses

EFI main relay

Fuel pump

ECM

Wiring connections
(g) Turn the ignition switch to LOCK.
(h) Disconnect the TOYOTA hand- held tester from the
DLC3.
2. CHECK FUEL PRESSURE

(b) Disconnect the negative (-) terminal cable from the bat-
tery.
(c) Purchase the new No.1 fuel pipe and take out the fuel
tube connector from its pipe.
