DTC P0443 EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
Revision: 2007 April2007 M35/M45
DTC P0443 EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
PFP:14920
DescriptionNBS005H4
SYSTEM DESCRIPTION
*1: ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to the ECM through CAN communication line.
This system controls flow rate of fuel vapor from the EVAP canister. The opening of the vapor by-pass pas-
sage in the EVAP canister purge volume control solenoid valve changes to control the flow rate. The EVAP
canister purge volume control solenoid valve repeats ON/OFF operation according to the signal sent from the
ECM. The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is
determined by considering various engine conditions. When the engine is operating, the flow rate of fuel vapor
from the EVAP canister is regulated as the air flow changes.
COMPONENT DESCRIPTION
The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canis-
ter. The EVAP canister purge volume control solenoid valve is
moved by ON/OFF pulses from the ECM. The longer the ON pulse,
the greater the amount of fuel vapor that will flow through the valve.

8. Remove cotter pin (1), and then loosen the nut.
9. Remove steering outer socket (2) from steering knuckle (3) so
as not to damage ball joint boot (4) using the ball joint remover
(suitable tool).
CAUTION:
Temporarily tighten the nut to prevent damage to threads
and to prevent the ball joint remover (suitable tool) from
suddenly coming off.
10. Remove drive shaft from wheel hub and bearing assembly.
11. Remove fixing nuts and bolts, and then remove shock absorber
arm. Refer to FSU-26, "
Components" .
12. Remove drive shaft from front final drive. (RH side)

Remove drive shaft from front final drive using the drive shaft
attachment [SST] and a drive shaft puller (suitable tool) while
inserting tip of the drive shaft attachment [SST] between
housing and front final drive as shown in the figure.
CAUTION:
Do not place drive shaft joint at an extreme angle when
removing drive shaft. Also be careful not to overextend side
shaft joint.
13. Remove fixing nuts and bolts, and then remove drive shaft from
vehicle. (LH side)
INSPECTION AFTER REMOVAL

Move joint up/down, left/right, and in the axial directions. Check for motion that is not smooth and for sig-
nificant looseness.

Check boot for cracks, damage, and leakage of grease.

Disassemble drive shaft and exchange malfunctioning part if
there is a non-standard condition.
INSTALLATION
CAUTION:
Always replace transaxle side oil seal with new one when installing drive shaft. Refer to FFD-11, "
SIDE
OIL SEAL" .

Installation is the reverse order of removal. For tightening torque refer to FA X - 11 , "COMPONENT" .

Place the protector [SST: KV38107900 ( – )] onto front final
drive to prevent damage to the oil seal while inserting drive
shaft. Slide drive shaft sliding joint and tap with a hammer to
install securely. (RH side)

CAUTION:

Every time the vehicle is lifted up, maintain the complete vehicle curb condition.

Since the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up point on the rear side garage jack with a mission
jack or equivalent.

Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the front side garage jack with a mission jack or
equivalent.

Be careful not to smash or do not do anything that would affect piping parts.
Garage Jack and Safety Stand and 2-Pole LiftNAS0007Z
WARNING:

Park the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes,
tubes, etc. under the vehicle.

Never get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.

Place wheel chocks at both front and back of the wheels on the ground.

When lifting the vehicle, open the lift arms as wide as possible and ensure that the front and rear
of the vehicle are well balanced.

When setting the lift arm, do not allow the arm to contact the brake tubes, brake cable, fuel lines
and sill spoiler.

Revision: 2007 April2007 M35/M45
HEADLAMP AUTO AIMING
Headlamp auto aiming control automatically corrects vertical deviation of light axis that is brought by the
change of vehicle height with changing number of passenger and laden weight, and relieves dazzle to oncom-
ing vehicles.
AFS control unit determines the current vehicle conditions by each received signals, and sends commands to
the low beam headlamps to auto aiming. With the headlamps (HIGH/LOW) illuminated and engine running,
the low beam headlamps are operative by AFS control unit commands.
The height sensor is located on the left side of the rear suspension member and detects rear vehicle height
change by sensing the displacement of the rear suspension arm. And transmits a height sensor signal to the
AFS control unit.
With reference to the rear vehicle height under the empty condition, light axis of low beam with low rear vehi-
cle height is relatively higher than that with the empty condition. AFS control unit switches drive signal corrects
height of low beam axis to maintain height of light axis with empty condition.
Light axis of low beam with high rear vehicle height is relatively lower than that with empty condition. Light axis
of low beam with empty condition is set as upper limit of headlamp auto aiming control operation. Control to
correct deviation is not performed when light axis of low beam gets relatively higher than that with empty con-
dition. Timing of control is switched in accordance with driving conditions.

Headlamp auto aiming operation
*1: Included high beam illuminated
*2: Control timing of drive signal is switched by vehicle speed and accelerating/decelerating vehicle.
*3: Control is performed without regard to the condition of AFS switch. Headlamp auto aiming control function cannot be cancelled.
