INSTALLATION
INSTALL ANTENNA ROD
(a) Insert the cable of the rod until it reaches the bottom.
HINT:
When inserting the cable, the teeth on the cable must face
toward the front of the vehicle.
Insert the antenna approx. 300 mm (11.8 in.)
(b) Wind the cable to retract the rod by turning the ignition
switch to the ”LOCK” position.
HINT:
If the ignition switch is already in the ”LOCK” position, per-
form step 1 (c) first, then turn the ignition switch to the
”ACC” position.
In case the cable is not wound, twist it as shown in the il-
lustration.
Even if the rod has not retracted fully, install the antenna
nut and inspect the antenna rod operation. It will finally re-
tract fully.
(c) Inspect the antenna rod operation by pushing the radio
wave band select buttons.

ELECTRIC COOLING FAN
ON−VEHICLE INSPECTION
1. CHECK COOLING FAN OPERATION WITH LOW TEM-
PERATURE (Below 83°C (181°F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
If not, check the cooling fan relay and ECT switch, and check
for a separated connector or severed wire between the cooling
fan relay and ECT switch.
(c) Disconnect the ECT switch connector.
(d) Check that the cooling fan rotates.
If not, check the fan main relay, cooling fan relay, cooling fan,
fuses, and check for short circuit between the cooling fan relay
and ECT switch.
(e) Reconnect the ECT switch connector.
2. CHECK COOLING FAN OPERATION WITH HIGH TEM-
PERATURE (Above 93°C (199°F))
(a) Start the engine, and raise coolant temperature to above
93°C (199°F).
(b) Check that the cooling fan rotates.
If not, replace the ECT switch.
3. INSPECT NO.1 COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the cooling fan connec-
tor.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage: 10.9 − 13.9 A
(d) Reconnect the cooling fan connector.
4. INSPECT NO.2 COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the cooling fan connec-
tor.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage: 9.1 − 11.1 A
(d) Reconnect the cooling fan connector.

HINT:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of the OBDII scan tool or
TOYOTA hand−held tester to DLC3, turned the ignition switch
ON and operated the scan tool, there is a problem on the ve-
hicle side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool’s instruction manual.
2. INSPECT DIAGNOSIS (Normal Mode)
(a) Check the MIL.
(1) The MIL comes on when the ignition switch is turned
ON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter.
(2) When the engine is started, the MIL should go off.
If the lamp remains on,the diagnosis system has
detected a malfunction or abnormality in the sys-
tem.
(b) Check the DTC.
NOTICE:
TOYOTA hand−held tester only:
When the diagnosis system is switched from normal mode
to check mode, it erases all DTC and freezed frame data re-
corded in normal mode. So before switching modes, al-
ways check the DTC and freezed frame data, and note them
down.
(1) Prepare the OBDII scan tool (complying with SAE
J1978) or TOYOTA hand−held tester.
(2) Connect the OBDII scan tool or TOYOTA hand−
held tester to DLC3 at the lower of the instrument
panel.
(3) Turn the ignition switch ON and turn the OBDII scan
tool or TOYOTA hand−held tester switch ON.
(4) Use the OBDII scan tool or TOYOTA hand−held tes-
ter to check the DTC and freezed frame data, note
them down.
(5) See page DI−14 to confirm the details of the
DTC.

− DIAGNOSTICSENGINE
1996 RAV4 (RM447U)
NOTICE:
When simulating symptoms with an OBDII scan tool (Ex-
cluding TOYOTA hand−held tester) to check the DTC, use
normal mode. For codes on the DTC chart subject to ”2 trip
detection logic”, turn the ignition switch OFF after the
symptom is simulated the first time. Then repeat the simu-
lation process again. When the problem has been simu-
lated twice, the MIL lights up and the DTC are recorded in
the ECM.
3. INSPECT DIAGNOSIS (Check Mode)
HINT:
TOYOTA Hand−Held Tester only:
Compared to the normal mode, the check mode has an in-
creased sensitivity to detect malfunctions.
Furthermore, the same diagnostic items which are detected in
the normal mode can also be detected in the check mode.
(a) Check the DTC.
(1) Initial conditions.
Battery positive voltage 11 V or more.
Throttle valve fully closed.
Transmission in park or neutral position.
Air conditioning switched OFF.
(2) Turn ignition switch OFF.
(3) Prepare the TOYOTA hand−held tester.
(4) Connect the TOYOTA hand−held tester to DLC3 at
the lower of the instrument panel.
(5) Turn the ignition switch ON and push the TOYOTA
hand−held tester main switch ON.
(6) Switch the TOYOTA hand−held tester normal mode
to check mode. (Check that the MIL flashes.)
(7) Start the engine. (The MIL goes out after the engine
starts.)
(8) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTC, etc.
(9) After simulating the malfunction conditions, use the
TOYOTA hand−held tester diagnosis selector to
check the DTC and freezed frame data, etc.
HINT:
Take care not to turn the ignition switch OFF. Turning the ignition
switch OFF switches the diagnosis system from check mode to
normal mode, so all diagnostic codes, etc. are erased.

(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
The following actions will erase the DTC and freezed
frame data.
(1) Operating the OBDII scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes.
(See the OBDII scan tool’s instruction book for oper-
ating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.
NOTICE:
If the TOYOTA hand−held tester switches the ECM from
normal mode to check mode or vice−versa, or it the ignition
switch is turned from ON to ACC or OFF during check
mode, the DTC and freezed frame data will be erased.
4. FAIL−SAFE CHART
If any of the following codes is recorded, the ECM enters fail−sate mode.
DTC No.Fail−Safe OperationFail−Safe Deactivation Conditions
P0105Ignition timing fixed at 5° BTDCReturned to normal condition
P0110Intake air temp. is fixed at 68°F (20°C)Returned to normal condition

P0120VTA is fixed at 0°
The following condition must be repeated at least
2 times consecutively
When closed throttle position switch is ON:

P0325Max. timing retardationIgnition switch OFF
P1300Fuel cutIGF signal is detected for 1 ignition
5. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA hand−held tester only:
By putting the vehicle’s ECM in check mode, 1 trip detection logic possible instead of 2 trip detection logic
and sensitivity to detect open circuit is increased. This makes it easier to detect intermittent problems.
(1) Clear the diagnostic trouble codes (See page DI−3)
(2) Set the check mode (See page DI−3)
(3) Perform a simulation test (See page IN−20)
(4) Check the connector and terminal inspection (See page IN−30)
(5) Visual check and contact pressure (See page IN−30)
(6) Handle the connector (See page IN−30)
