EGR SYSTEM CHECKM1173002600348
1. Disconnect the vacuum hose (Green stripe) from
the EGR valve, and then connect a hand vacuum
pump via the three-way terminal.
2. When the engine is hot or cold, check the
condition of vacuum by racing the engine.
When engine is cold
(Engine coolant temperature: 20°C or less)
When engine is hot
(Engine coolant temperature: 80°C or higher)
3. Disconnect the three-way terminal.4. Connect the hand vacuum pump to the EGR
valve nipple.
5. Check whether the engine stalls or the idling is
unstable when a vacuum of 30 kPa or higher is
applied during idling.
EGR VALVE CHECKM1173002800223
1. Remove the EGR valve and inspect for sticking,
carbon deposits, etc. If found, clean with a
suitable solvent so that the valve seats correctly.
2. Connect a hand vacuum pump to the EGR valve.
3. Apply 67 kPa of vacuum, and check that the
vacuum is maintained.
4. Apply a vacuum and check the passage of air by
blowing through one side of the EGR passage. Throttle valve Normal vacuum condition
Open quickly No vacuum will generate (the
same as barometric pressure.)
Throttle valve Normal vacuum condition
Open quickly It will momentarily rise over 13
kPa

5. Replace the gasket, and tighten to the specified
torque.
Tightening torque:
<4G1> 21 ± 4 N⋅m
<4G6> 20 ± 2 N⋅m
EGR PORT VACUUM CHECK <4G1>M1173002900167
1. Disconnect the vacuum hose (Green stripe) from
the throttle body EGR vacuum nipple and connect
a hand vacuum pump to the nipple.
2. Plug the vacuum hose (Green stripe).
3. Start the engine and check that, after raising the
engine speed by racing the engine, purge vacuum
raises according to engine speed.
NOTE: If there is a problem with change in
vacuum, the throttle body purge port may be
clogged and require cleaning.
EGR PORT VACUUM CHECK <4G6>M1173002900156
1. Disconnect the vacuum hose (White stripe) from
the throttle body EGR vacuum nipple and connect
a hand vacuum pump to the nipple.
2. Plug the vacuum hose (White stripe).
3. Start the engine.
4. Check that a fairly constant negative is generated
regardless of the engine speed.
5. If no negative pressure is generated, the port is
probably blocked and should be cleaned.
EGR CONTROL SOLENOID VALVE
CHECK <4G1>
M1173003100238
NOTE: When disconnecting the vacuum hose,
always make a mark so that it can be reconnected at
original position.
1. Disconnect the vacuum hose from the solenoid
valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the
solenoid valve (refer to the illustration at left).
4. Check air tightness by applying a vacuum with
voltage applied directly from the battery to the
EGR control solenoid valve and without applying
voltage.

GENERAL INFORMATION
M1321000100340The engine mounting system employs the inertial
axis four-point suspension method, which is field
proven.
•The optimised locations of the front and rear roll
mounts well distribute their loads thereby
reducing engine idling vibrations.•The fore-and-aft, liquid-filled engine mount of
cylinder type is adopted to reduce engine shake
for improved riding comfort.
