er window switch in ”UP” position and check that there is
a circuit breaker operation noise within 4 to 40 seconds.

Repeating (c) to (i) in the step 4, check the actuator operation
similarly.
HINT:
When inspecting the ”REAR LH” position, push the REAR LH
switch instead of the POWER SWITCH. This makes it possible
to inspect wherever the selector switch position indicates.
8. PUSH MOTOR SWITCH
(a) Push and hold in the MOTOR switch for a few seconds.
(b) Stop the engine.

Remove the ”SHEET A” (SST) and disconnect the actuator
checker (SST) and sub−wire harness (SST) from the actuator,
control relay and body side wire harness.

4. ECU (ELECTRONIC CONTROL UNIT)
Locations of ECUs
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.

Before starting electric welding operations, disconnect the negative (-) terminal cable from the battery.
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are all
equipped with memory function, it is not possible to make a record of the memory contents.
So when the operation is finished, it will be necessary to explain this fact to the customer, and request
the customer to adjust the features and reset the memory.

Do not expose the ECUs to ambient temperatures above 80°C (176°F).
NOTICE: If it is possible the ambient temperature may reach 80 °C (176 °F) or more, remove the ECUs
from the vehicle before starting work.

Be careful not to drop the ECUs and not to apply physical shocks to them.
4. COMPONENTS ADJACENT TO THE BODY PANELS
Various types of component parts are mounted directly on or adjacently to the body panels.
Strictly observe the following precautions to prevent damaging these components and the body panels
during handling.

Before repairing the body panels, remove their components or apply protective covers over the comœ
ponents.

Before prying components off using screwdriver or a scraper, etc., attach protective tape to the tool
tip or blade to prevent damaging the components and the body paint.

Before removing components from the outer surface of the body, attach protective tape to the body to
ensure no damage to painted areas.
HINT: Apply touch-up paint to any damaged paint surfaces.

Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side.

(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.

DTC P0401 Exhaust Gas Recirculation Flow Insufficient
Detected
CIRCUIT DESCRIPTION
The EGR system recirculates exhaust gas, which is controlled to the proper quantity to suit the driving condi-
tions, into the intake air mixture to slow down combustion, reduce the combustion temperature and reduce
NOx emissions. The amount of EGR is regulated by the EGR vacuum modulator according to the engine
load.
If even one the following conditions is fulfilled, the VSV is turned
ON by a signal from ECM. This results in atmospheric air acting
on the EGR valve, closing the EGR valve and shutting off the
exhaust gas (EGR cut−off).
Before the engine is warmed up
During deceleration (throttle valve closed) .
Light engine load (amount of intake air very small).
Engine idling.
Engine speed over 4,400 rpm.
High engine load (amount of intake air very large)
