AVENSIS REPAIR MANUAL (RM1018E)

Do not apply heat directly to the parts in the ECU.
3. WATER SPRINKLING METHOD: When the malfunc-
tion seems to occur on a rainy day or in high±humid-
ity.
(a) Sprinkle water onto the vehicle and check if the malfunc-
tion occurs.
NOTICE:

Never sprinkle water directly onto the engine
compartment, but indirectly change the temperature
and humidity by spraying a mist of water onto the ra-
diator front surface.

Never apply water directly onto the electronic compo-
nents.
HINT:
If a vehicle is subject to water leakage, the leaking water may
contaminate the ECU. When testing a vehicle with a water leak-
age problem, this factor must also be considered.
4. OTHERS: If the malfunction seems to occur when
electrical load is excessive.
(a) Turn on all the electrical equipment including the heater
blower, headlights, rear window defogger, etc., and check
if the malfunction occurs.

HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS
GENERAL INFORMATION
There are many ECU controlled systems used in the AVENSIS. In general, ECU controlled system are con-
sidered to be very intricate and require a high level of technical knowledge an\
d expert skill to troubleshoot.
The fact is, however, that if you proceed by inspecting the circuits one by one, troubleshoo\
ting of these sys-
tems is not complex. If you have adequate understanding of the system and ba\
sic knowledge of electricity,
the problem can be accurately diagnosed and fixed. This manual is design\
ed based on the above principle
to help service technicians perform accurate and effective troubleshooting, and is compiled for the following
major ECU controlled systems:
The troubleshooting procedures are described on the following pages.

FOR USING HAND±HELD TESTER

Before using the tester, the tester's operator manual should be read thoroughly.

If the tester cannot communicate with the ECU controlled systems when you \
have connected the cable
of tester to the DLC3, turned the ignition switch ON and operated the test\
er, there is a problem on the
vehicle side or tester side.
(1) If the communication is normal when the tester is connected to another veh\
icle, inspect the diag-
nosis data link line (Bus
line) or ECU power circuit of the vehicle.
(2) If the communication is still impossible when the tester is connected to a\
nother vehicle, the prob- lem is probably in the tester itself, so perform the Self Test procedures outlined in the Tester Oper-
ator 's Manual.
