2. AIRBAG COMPONENT PARTS APPEARANCE
INSPECTION
Conduct appearance inspection on parts selected.
NOTE:
Also check connector terminals, wiring harness, case, etc.
for damage.
3. AIRBAG COMPONENT PARTS VIBRATION
INSPECTION
1) Gently shake check parts (to determine faults.).
2) To check airbag module or roll connector, turn and tilt
steering wheel.
CAUTION:
Do not shake or vibrate airbag control module and
front sensor at the same time as erroneous operation
may result.

4. SHOWERING INSPECTION TO BODY
1) Spray water on vehicle body.
CAUTION:
Do not directly spray water on airbag components.
2) Check passenger compartment for traces of leaking.
NOTE:
Also check wiring harnesses as water may leak along them
and get airbag component parts wet.

4. SHOWERING INSPECTION TO BODY
1) Spray water on vehicle body.
CAUTION:
Do not directly spray water on each part.
2) Check passenger compartment for traces of leaking.
NOTE:
If leaks are noted, check wiring harnesses as water may
leak along them and get parts wet.
5. WARNING LIGHT ILLUMINATION CHECK
Turn ignition switch“ON”(engine off) and observe airbag
warning light.
Airbag warning light comes“ON”for 8 seconds then goes
out and stays out.

1. Supplemental Restraint System
“Airbag”
Airbag system wiring harness is routed near the cruise
control command switch.
CAUTION:
All Airbag system wiring harness and connectors
are colored yellow. Do not use electrical test equip-
ment on these circuits.
Be careful not to damage Airbag system wiring har-
ness when servicing the cruise control command
switch.

2. Pre-inspection
1. CRUISE CONTROL CABLE
1) Cable installation
(1) Ensure that cruise control cable is attached to the left
of accelerator cable (on accelerator pedal side).
(2) Ensure that accelerator cable throttle cam does not
move when cruise control throttle cam is moved by hand.
(3) Ensure that throttle cam moves smoothly.
2) Cable free play
(1) Ensure that throttle cam-to-lever clearance is within
specifications.
Standard value: 1
0
1mm (0.040
0.04in)
NOTE:
If clearance is not within specifications, adjust cable at its
outer end.
(2) Ensure that cap is positioned in groove.

2. VACUUM HOSE AND PIPE
Check vacuum hose and pipe (which connects actuator
and vacuum pump) for disconnection or cracks.
B6M0270A
3. ACTUATOR
1) Disconnect vacuum hose from actuator.
B6M0174
2) Connect vacuum pump as shown in figure.
3) Make sure that cruise control cable moves smoothly
and quickly when a vacuum pressure of 40.0 kPa (300
mmHg, 11.81 inHg) is applied to actuator.
Stroke: 35 mm (1.38 in)
4) When vacuum pressure is released from condition 3)
above, make sure the cable returns to its original position
smoothly and quickly.
5) After inspection, disconnect vacuum pump and connect
vacuum hose.
4. POWER SUPPLY
1) Measure battery voltage and specific gravity of electro-
lyte.
Standard voltage: 12 V
Specific gravity: Above 1.260
2) Check the condition of the main and other fuses, and
harnesses and connectors. Also check for proper ground-
ing.
