INTRODUCTION HOW TO TROUBLESHOOT ECU CONTROLLED
SYSTEMS
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.

PROBLEM SYMPTOMS TABLE
The suspected circuits or parts for each problem symptom are shown in the t\
able below. Use this table to
troubleshoot the problem when a Normal code is displayed in the diagnostic trouble c\
ode chart but the prob-
lem is still occurring. Numbers in the table indicate the order in which\
the circuits or parts should be checked.
HINT:
When the problem is not detected by the diagnostic system even though the pr\
oblem symptom is present,
it may be that the problem is occurring outside the detection range of t\
he diagnostic system.
Symptom Suspected AreaSee page
1. With the ignition switch in ACC or ON position, the SRS warning
light sometimes lights up after approx. 6 seconds have elapsed.
2. SRS warning light is always lit up even when ignition switch is
in the LOCK position
1. With the ignition switch in the ACC or ON position, the SRS
warning light does not light up.

HINT:
Check with your hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
5. VISUALLY CHECK GENERATOR WIRING
(a) Check that the wiring is in good condition.
6. LISTEN FOR ABNORMAL NOISES FROM GENERATOR
(a) Check that there is no abnormal noise from the generator while the engin\
e is running.
7. INSPECT CHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ON. Check that the charge warning light comes on\
.
(b) Start the engine and check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the charge warn\
ing light circuit. 8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) According to the following procedure, connect an amme-
ter and voltmeter as shown in the illustration.
(1) Disconnect the wire from terminal B of the generatorand connect it to the negative (±) lead of the amme-
ter.
(2) Connect the positive (+) lead of the ammeter to ter- minal B of the generator
(3) Connect the positive (+) lead of the voltmeter to ter- minal B of the generator.
(4) Ground the negative (±) lead of the voltmeter.
(b) Check the charging circuit. (1) Keep the engine speed at 2,000 rpm, check thereading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 12.9 to 14.9 V
HINT:

If the voltmeter reading is more than standard voltage, re-
place the voltage regulator.

If the voltmeter reading is less than the standard voltage,
check the voltage regulator and generator as follows:
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) Keep the engine speed at 2,000 rpm, turn on the high beam headlights and\
turn the heater blower switch to the ºHIº position.
(b) Check the reading on the ammeter. Standard amperage: 30 A or more
HINT:

If the ammeter reading is less than standard amperage, repair the genera\
tor.

If the battery is fully charged, the indication will sometimes be less t\
han standard amperage.
