(d) Map matching
The current driving route is calculated by
autonomous navigation (according to the gyro
sensor and vehicle speed sensor) and GPS
navigation. This information is then compared with
possible road shapes from the map data in the map
disc and the vehicle position is set onto the most
appropriate road.

INITIALIZATION
NOTICE:
• Resetting the power window motor (initializing the
pulse sensor) is necessary when the battery terminal
is disconnected; when the master switch, wire
harness, power window regulator and power window
motor are replaced or removed/installed; or when the
fuses are replaced. AUTO operation function, jam
protection function and remote operation function via
the power window master switch do not operate
without resetting.
• If the AUTO switch (driver side switch) of the master
switch has been continuously operated for a long
time, the power window motor will stop so that no
additional load can be applied to the motor.
Continuing to operate the switch even after the motor
has stopped will cause the switch to blink while
restricting the AUTO UP/DOWN function and the
remote UP/DOWN function. If this happens, reset the
motor again after several minutes have passed.
• Whenever disconnecting the battery terminal, reset all
the other systems besides the power window control
system.
1. RESET POWER WINDOW REGULATOR MOTOR
(DRIVER SIDE)
(a) Turn the ignition switch ON.
(b) Halfway open the power window by pressing the
power window switch.
(c) Fully pull up the switch until the power window is
fully closed and continue to hold the switch for
approx. 1 second after the power window is fully
closed.
(d) Check that the AUTO UP/DOWN function operates
normally.
If the AUTO UP/DOWN function operates normally,
reset operations have been completed at this time.
If not normal, follow steps below.
(1) Disconnect the negative battery terminal for 10
seconds.
(2) Connect the battery terminal.
(3) Perform the above steps (a) to (d) again.
HINT:
If operation is normal, reset operations have
been completed at this time. If not normal, follow
steps (4) to (7).
(4) Turn the ignition switch ON.
(5) Halfway open the power window by pressing the
power window switch.
(6) Fully pull up the switch until the power window is
fully closed and continue to hold the switch for
approx. 12 seconds after the power window is
fully closed.
(7) Check that the AUTO UP/DOWN function
operates normally.

PRECAUTION
1. INITIALIZATION
NOTICE:
• Perform RESET MEMORY (AT initialization) when
replacing the automatic transaxle assembly, engine
assembly or ECM (See page AX-16).
• Perform REGISTRATION (VIN registration) when
replacing the ECM (See page ES-15).
HINT:
Initialization cannot be completed by only removing the
battery.
2. FOR USING INTELLIGENT TESTER
CAUTION:
Observe the following items for safety reasons:
• Before using the tester, read the instruction
manual.
• Prevent the tester cable from being caught on the
pedals, shift lever and steering wheel when
driving with the tester connected to the vehicle.
• When driving the vehicle for testing purposes
using the tester, two persons are required. One is
for driving the vehicle, and the other operates the
tester.
3. FOR USING BATTERY DURING INSPECTION
(a) While using the battery during inspection, do not
bring the positive and negative tester probes too
close to each other as a short circuit may occur.
4. COOLING FAN SYSTEM
NOTICE:
• When the ignition switch is turned off and the engine
temperature is high, the cooling fans may operate for
approximately 3 minutes.
• After turning the ignition switch off, keep hands and
objects away from the fans when they are operating.
HINT:
If all of the following are met for a certain period of time during
a few minute period immediately before the engine is
stopped, the electric fans will continue to operate for 3
minutes after the engine is stopped. This is performed to
ensure restartability and stabilize idle speed.
– The intelligent tester indicates a very high coolant
temperature.
– The intelligent tester indicates a high outside air
temperature.
– The vehicle has been driven under high load (driving on an
uphill or equivalent).
The following sensors are used for this control:
– Coolant temperature sensor
– Outside air temperature sensor
–MAF sensor
– Vehicle speed sensors

DEFINITION OF TERMS
Terms Definitions
Monitor Description Description of what ECM monitors and how to detect malfunctions (monitoring purpose and details).
Related DTCs A group of diagnostic trouble codes that are output by ECM based on the same malfunction detection logic.
Typical Enabling
ConditionsPreconditions that allow ECM to detect malfunction.
With all preconditions satisfied, ECM sets DTC when monitored value(s) exceeds malfunction threshold(s).
Sequence of OperationOrder of monitor priority, applied if multiple sensors and components are involved in single malfunction detection
process.
Each sensor and component monitored in turn and not monitored until previous detection operation is completed.
Required Sensors /
ComponentsSensors and components used by ECM to detect each malfunction.
Frequency of OperationNumber of times ECM checks for each malfunction during each driving cycle.
"Once per driving cycle" means ECM performs checks for that malfunction only once in single driving cycle.
"Continuous" means ECM performs checks for that malfunction whenever enabling conditions are met.
DurationMinimum time for which ECM must detect continuous deviation in monitored value(s) in order to set DTC. Timing
begins when typical enabling conditions are met.
Malfunction Thresholds Values, beyond which, ECM determines malfunctions exist and sets DTCs.
MIL OperationTiming of MIL illumination after defect is detected.
"Immediate" means ECM illuminates MIL as soon as malfunction is detected.
"2 driving cycles" means ECM illuminates MIL if the same malfunction is detected twice during the next sequential
driving cycle.

DESCRIPTION
The exhaust camshaft's Variable Valve Timing (VVT) sensor consists of a magnet and MRE (Magneto
Resistance Element).
The exhaust camshaft has a sensor plate with 3 teeth on its outer circumference.
When the exhaust camshaft rotates, changes occur in the air gaps between the 3 teeth and MRE, which
affects the magnet. As a result, the resistance of the MRE material fluctuates. The VVT sensor converts
the exhaust camshaft rotation data to pulse signals, uses the pulse signals to determine the camshaft
angle, and sends it to the ECM.
MONITOR DESCRIPTION
If no signal is transmitted by the VVT (for exhaust camshaft) sensor despite the engine revolving, or the
rotations of the exhaust camshaft and the crankshaft are not synchronized, the ECM interprets this as a
malfunction of the sensor.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data
can be helpful in determining whether the vehicle was running or stopped, whether the engine was
warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of
a malfunction.
(a) Disconnect the C21 or C20 VVT sensor connector.
(b) Measure the voltage according to the value(s) in the
table below.

Exhaust camshaft sensor signal Less than 0.3 V
