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.

5. VACUUM PUMP AND VALVE
1) Measure resistance of vacuum pump and valve.
(1) Disconnect connector from vacuum pump and valve.
(2) Measure resistance between each terminal of
vacuum pump and valve.
Terminals / Specified resistance:
No. 2—No. 3 / 100Ωor less (Vacuum pump
motor)
No. 2—No. 1 / 69Ω(Air valve)
No. 2—No. 4 / 69Ω(Release valve)
B6M0272
2) Check for leakage and sticking of vacuum valve.
(1) Disconnect connector from vacuum pump and valve.
(2) Make sure that cruise control cable moves smoothly
when connecting + (positive) battery cable to terminal
No. 2 and (negative) battery cable to terminals No. 1,
3 and 4 of vacuum pump and valve connector.
Stroke: 35 mm (1.38 in)
Movement time: Within 3 seconds
(3) When the battery cable is disconnected from condi-
tion (2) above, make sure the cable returns to its origi-
nal position smoothly.
Movement time: Within 1.5 seconds
(4) Connect battery to each terminal and check cable
movement.
