COOLING FAN SYSTEM (1ZZ±FE/3ZZ±FE)
ON±VEHICLE INSPECTION
HINT:
It is normal that the cooling fan sometime rotates when the ignition switc\
h is turned from ACC to ON.
1. CHECK COOLING FAN OPERATION WITH LOW TEMPERATURE (Below 94.5
C (202
F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
If not, check the cooling fan relay and engine coolant temperature sensor, and check if there is its connector
disconnection or circuit open between them.
(c) Disconnect the engine coolant temperature sensor connector.
(d) Check that the cooling fan rotates.
If not, check the fuses, cooling fan relay, ECM and cooling fan, and check for short in a circuit between the
cooling fan relay and the engine coolant temperature sensor.
(e) Reconnect the engine coolant temperature sensor connector.
2. CHECK COOLING FAN OPERATION WITH HIGH TEMPERATURE (Above 96
C (205
F))
(a) Start the engine, and raise coolant temperature to above 96
C (205
F).
HINT:
Coolant temperature is detected by the engine coolant temperature sensor\
on the water outlet.
(b) Check that the cooling fan rotates.
If not, replace the engine coolant temperature sensor.
3. INSPECT COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the connector.
(c) Check that the cooling fan rotates smoothly, and check the reading on the ammeter. Standard amperage: Approximately. 8 to 12 A at 20
C (68
F)
(d) Reconnect the cooling fan connector.

LUBRICATION SYSTEM (1CD±FTV)
ON±VEHICLE INSPECTION
1. CHECK ENGINE OIL LEVEL
(a) After warm up the engine and then 5 minutes after the engine stop, oil l\
evel should be between the low level and full level marks of the dipstick.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.
2. CHECK ENGINE OIL QUALITY
(a) Check the oil for deterioration, entry of water, discoloringor thinning.
If the quality is visibly poor, replace the oil. Oil grade:
Use ACEA B1, API grade CF ± 4 or CF
(You may also use API CE or CD)
SAE 5W ± 30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold weath-
er.
3. REMOVE OIL PRESSURE SWITCH ASSY
(a) Disconnect the oil pressure switch connector.
(b) Using a deep socket wrench 24mm, remove the oil pres- sure switch.
4. INSTALL OIL PRESSURE GAUGE
(a) Install the oil pressure gauge.
5. WARM UP ENGINE

AVENSIS REPAIR MANUAL (RM1018E)
ON±VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL
(a) Check the electrolyte quantity of each cell.
(1) If the electrolyte is under the low level, replace the battery (or add di\
stilled water if possible) andcheck the charging system.
2. CHECK BATTERY VOLTAGE
(a) If it has not been 20 minutes since you drove the vehicleor since the engine was stopped, turn the ignition switch
and the electrical system (headlight, blower motor, rear
defogger etc.) to the on position for 60 seconds. This will
remove the surface charge on the battery.
(b) Turn off the ignition switch and the electrical systems.
(c) Measure the battery voltage between the negative (±) and positive (+) terminals of the battery.
Standard voltage: 12.5 to 12.9 V at 20 C (68 F)
HINT:
If the voltage is less than specification, charge the battery.
(d) Check the indicator as shown in the illustration.

3. CHECK BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Check that the battery terminals are not loosened or corroded.
(b) Check the fusible links, high±current fuses and regular fuses.
4. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cordsetc.
HINT:

If any defect found, replace the drive belt.

Cracks on the rib side of a belt are considered acceptable.
If the belt has chunks missing from the ribs, it should be
replaced.

(a) Airtightness check.
(1) Start the engine and stop it after 1 or 2 minutes. De-press the brake pedal several times slowly.
HINT:
If the pedal can be depressed to the f;oor the first time, but on
the 2nd or 3rd time cannot be depreesed as far, the booster is
airtight. (2) Depress the brake pedal while the engine is run-
ning, and stop the engine with the pedal depressed.
HINT:
If there is no change in the pedal reserve distance after holding
the pedal for 30 seconds, the booster is airtight.
(b) Operating check. (1) Depress the brake pedal several times with the igni-tion switch off and check that there is no change in
the pedal reserve distance.
(2) Depress the brake pedal and start the engine.
HINT:
If the pedal goes down slightly, operation is normal.
2. INSPECT VACUUM CHECK VALVE
(a) Inspect vacuum check valve. (1) Slide the clip and disconnect the vacuum hose.
(2) Remove the vacuum check valve.
(3) Check that there is ventilation from the booster to
the engine, and no ventilation from the engine to the
booster.
(4) If any fault is found, replace the vacuum check
valve.
