± 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.

DETECTED
DTC P0301 CYLINDER 1 MISFIRE DETECTED
DTC P0302 CYLINDER 2 MISFIRE DETECTED
DTC P0303 CYLINDER 3 MISFIRE DETECTED
DTC P0304 CYLINDER 4 MISFIRE DETECTED
CIRCUIT DESCRIPTION
Misfire: The ECM uses the crankshaft position sensor and camshaft position sensor to monitor changes in
the crankshaft rotation of each cylinder.
The ECM counts the number of times from the engine speed change rate, indicating that misfire has oc-
curred. When the misfire rate equals to or exceeds the count, indicating that the engine condition has deteri-
orated, the CHK ENG is illuminated.
If the misfire rate is high enough and the driving conditions causes the catalyst to overheat, the CHK ENG
blinks when the misfire occurs.
HINT:

For any particular 200 revolutions of engine, misfiring which could result in overheating of catalyst is
detected. This cause CHK ENG to blink (1 trip detection logic).

For any particular 1,000 revolutions of engine, misfiring which could result in a deterioration of emis-
sions is detected. This cause CHK ENG to illuminate (2 trip detection logic).
