± INTRODUCTIONREPAIR INSTRUCTION
AVENSIS REPAIR MANUAL (RM1018E)
NOTICE:

Confirm that the VSC warning light blinks.

VSC system will be reset when the engine is re-
started.

Fasten the vehicle with lock chains.
(b) NOTICES OF RELATED OPERATIONS TO VSC
(1) Do not carry out unnecessary installation and re-
moval as it might disorder the adjustment of related
parts to VSC.
(2) Be sure to carry out the preparation for operation
and the confirmation of operation completion in ac-
cordance with the instruction of the text and when
the related operations to VSC are performed.
10. FOR VEHICLES EQUIPPED WITH CATALYTIC CONVERTER
CAUTION:
If a large amount of unburned gasoline flows into the converter, it may cause overheating and is a
fire hazard. To prevent this, observe the following precautions.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid idling the engine for more than 20 minutes.
(c) Avoid a spark jump test.
(1) Perform a spark jump test only when absolutely necessary. Perform this test as rapidly as pos-
sible.
(2) While testing, never race the engine.
(d) Avoid a prolonged engine compression measurement.
Engine compression measurements must be performed as rapidly as possible.
(e) Do not run the engine when the fuel tank is nearly empty. This may cause the engine to misfire and
create an extra load on the converter.

ON±VEHICLE INSPECTION
NOTICE:
Turn the ignition switch OFF for 60 seconds before performing the following inspections.
1. INSPECT LIGHTING DURATION OF GLOW INDICA-
TOR LIGHT
(a) Turn the ignition switch ON, and measure the lighting
duration.
Light lighting duration: Refer to the chart graph
2. INSPECT PRE±HEATING
(a) Turn the ignition switch ON, measure how long it takes to
the battery voltage is applied to the glow plugs.

AVENSIS REPAIR MANUAL (RM1018E)
4. INSPECT GLOW PLUGS
(a) Using an ohmmeter, check that there is continuity be-
tween the glow plug terminal and ground.
Standard resistance: Approx. 0.72
at 20C (68F)
NOTICE:

Be careful not to damage the glow plug pipes as it
could cause an open circuit or shorten life of the glow
plugs.

Avoid getting oil and gasoline on the glow plug when
cleaning.

Wipe up any oil on the terminal and Bakelite washer
with a dry cloth if they are stained with oil during in-
spection.

Be careful not to apply more than 11 V to the glow plug
as it could cause an open circuit.
