1. Disconnect the 7P connector from the mode control
motor. Remove the rod from the arm of the mode
control motor, Remove the self-tapping screws and
the mode control motor.
2.Install in the reveGe order of removal. After installa-
tion, make sure the mode control motor runssmoothlv.

MODE CONTROL MOTOR
Test
1.Disconnect the 7P connector from the mode control
motor.
Connect battery power to the No. 1 terminal, andground the No. 7 terminal. To avoid damaging the
mode control motor, do not reverse power andgrouno.
MODE CONTROL MOTOR
Using a jumper wire. connect the No. 7 terminalindividually to the No, 2,3, 4,5 and 6 terminals in
that order. Each time the connection is made. the
mode control motor should run smoothly and stop.
lf the mode control motor does not run when jump-
ing the first terminal, jump that terminal again afterjumping the other terminals. The mode control
motor is OK it it runs when jumping the first termi-
nal again.
lf the mode control motor does not run in step 3,remove it, then check the mode control linkage and
doors for smooth movement. lf they move smoothly,
reDlace the mode control motor.

A/G System Service
Performance Test
The performance test will helD determine if the air con-
ditioner system is operating within specifications.
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner svstem.
CAUTION: Exposure to air condiiioner r€trigerant and
lubricant vapor or mist can irritate €yes, nose and
throat. Avoid bre8thing the air conditioner retrige.ant
and lubricant vapor or mist,
lf accidental system discharge occurs. ventilate work
area before resuming service.
R-134a service equipment o. vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
comDressed air.
@ some mixtur€s ol air and R-134a have becn
shown to be combuslible at olsvated pressures and can
result in lire or explosion causing iniury or property
damage. Never use compressed air to prgssure test R-
13i[a service equipment or vehicle air conditioner sys.
tems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.

Insen a thermometer in the center air vent. Determine
the relative humidity and air temperature.
Test conditions:
. Avoid direct sunlight.
o Open hood.
. open front doors.
. Set the temperature control dial on MAX COOL,
the mode control dial on VENT and the reci.cula-
tion control switch on RECIRCULATE.
. Turn the A,/C switch on and the fan switch on

NOTE:
. The ceiling light (in middle position) comes on within 30 seconds when you unlock the doors with the transmitter.
. The doors do not lock or unlock with the transmitter if the ignition key is in the ignition switch.
. lf any door is open, you cannot lockthe doorswith thetransmitter.
o lf you unlock the doors with the transmitter, but do not open any of the doors within 30 seconds, the doors relock auto-
matically.
. For hatch glass button operation, hold the button for more than two seconds.
. lf you press the PANIC button for more than two seconds, the horn sounds for about 30 seconds, and the transmitter
LED comes on. (The panic mode will not be activated if the ignition key is in the ignition switch.) The panic mode is
cancelled by pressing any of the transmitter buftons.
. The horn sounds only the first time you press a transmitter button, (Pressing repeatedly does not activate the horn
again.)

. It the green light on the tool comes on, the air-
bag igniter circuit is defective and cannot deploy
the airbag. Go to Damaged Airbag Special
Procedure.
.lftheredlightonthetool comes on, the airbag is
ready to be deployed.
Push the tool's deployment switch. The airbag
should deploy (deployment is both highly audible
and visible; a loud noise and rapid inflation of the
bag, followed by slow deflation).
. lf the airbags deploy and the green light on the
tool comes on, continue with this procedure.
. lf an airbag doesn't deploy, yet the green light
comes ON, its igniter is defective. Go to Dam-
aged Airbag Special Procedure.
. During deployment, the airbag can become hot
enough to burn you, Wait thirty minutes after
deployment before touching the airbag.
Dispose of the complete airbag. No part of it can be
reused. Place it in a sturdy plastic bag, and seal it
securety.
CAUTION:
. Wear a faco shield and gloves when handling a
deployed airbag.
. Wash your hands and rinse them well with
water after handling a deployed airbag.

Deploying tho Airbag: Out-ot.vohicle
lf an intact airbag has been removed from a scrapped
vehicle, or has been found defective or damagsd during
transit. storage or seryice, it should be deployed as fol-
lows:
'L Confirm that the special tool is functioning properly
by following the check procedure on this page or on
the tool label.
2. Position the airbag face up, outdoors on flat ground
at least thirty feet (10 m) from any obstacles or peo-
Dte,
3. Follow steps 6, 7, 8. and 9 of the in-vehicle deploy-
ment proceoure.

Procgdure
!@ r an airbag {or seat Beh rensioner} cannol
be doployod, it should not be treated as normal scrap; it
should still be considered a pot€ntially explosive device
lhat can cause serious iniury.
1. lf installed in a vehicle. follow the removal proce-
dure on page 24-3 and 24-87 through 90.
2. In all cases, make a short circuit by twisting together
the two airbag inflator wires.
3. Package the airbag in exactly the same packaging
that the new reDlacement Dart came in.
4. Mark the outside of the box "DAMAGED AIRBAG
{or TENSIONER) NOT DEPLOYED" so it does not
get confused with your parts stock.5. Contact your Honda District Service Manager forhow and where to return it for disposal.
Deployment Tool: Check Procedure
Connect the yellow clips to both switch protector
handles on the tool; connect the tool to a battery.
Push the operation switch: green means the tool is
OK: red means the tool is faultv.
Disconnect the baftery and the yellow clips.
