Heating and Air Conditioning
Refrigerant Leak Test
Special Tool Required
Leak detector, Honda Tool and Equipment YGK-H-10PM
commerciallv available
Compressed air mixed with R-134a forms a
combustible vapor.
The vapor can burn or explode causing serious
injury.
Never use compressed air to pressure test
R-134a service equipment or vehicle air
conditioning system.
Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose, or throat.
Be carefulwhen connecting service equipment.
Do not breathe refrigerant or vapor
Use only service equipment that is U.L.-listed and is
certiified to meet the requirements of SAE J2210 to
remove HFC-134a (R-134a) from the air conditioning
system.
lf accidental system discharge occurs, ventilate the
work area before resuming service.
R-134a service equipment or vehicle air conditioning
systems should not be pressure tested or leak tested
with compressed air.
Additional health and safety information may be
obtained from the refrigerant and lubricant
manufacturers.

1. Connect a R-134a refrigerant recovery/recycling/
charging station (A) to the high-pressure serviceport (B) and the low-pressure service port (C), as
shown, following the equipment manufacturer's
anstructions.
Open the high pressure valve to charge the system
to the specified capacity, then close the supply
valve, and remove the charging system couplers.
Select the appropriate units of measure for your
refrigerant charging station.
Refrigerant capacity:
500 to 550 g
0.50 to 0.55 kg
1.10 to 1.21 lbs
17.6 to 19.4 oz
Check the system for leaks using a R-134a
refrigerant leak detector with an accuracy of 14 g(0.5 oz) per year or better.
lf you find leaks that require the system to be
opened (to repair or replace hoses, fittings, etc.),
recover the system.
After checking and repairing leaks, evacuate the
system.

A/C System Tests (cont'd)
1.
Performance Test
Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose, or throar.
Be carefulwhen connecting service equipment.
Do not breathe refrigerant or vapor.
The performance test will help determine if the air
conditioner system is operating within specifications.
Use only service equipment that is U.L.-listed and is
cenified to meet the requirements of SAE J2210 toremove HFC-134a (R-134alfrom the air conditioning
system.
lf accidental system discharge occurs, ventilate the
work area before resuming service
R-134a service equipment or vehicle air conditioning
systems should not be pressure tested or leak testedwith compressed air.
Additional health and safety information may be
obtained from the refrigerant and lubricant
manufacturers.
Connect a R-134a refrigerant recover/recycling/
charging station to the high-pressure service port
and the low-pressure service port, following the
equipment manufacturer's instructions.
Determine the relative humidity and air
Iemperaru re.
' Compressed air mixed with R-134a forms a
combustible vapor.. The vapor can burn or explode causing serious
Injury.. Never use compressed air to pressure test
R-134a service equipment or vehicle air
conditioning systems.

Open the glove box. Remove both glove box stops,
then let the glove box hang down (see page 20-63).
Insert a thermometer (A) in the center vent, andplace another thermometer {B) near the blower unit.
Test conditions:
. Avoid direct sunlight.. Open the hood.. Open the front doors.. Sel the temperature control dial on Max Cool, the
mode control dial on Vent, and the recirculation
control switch on Recirculate.. Turn the A,/C switch on and the fan switch on Max.. Run the engine at 750 rpm.. No driver or passengers in vehicle.
After running the air conditioning for I0 minutes
under the above test conditjons, read the delivery
temperature from the thermometer in the center
vent, the intake temperature near the blower unit,
and the high and low system pressure from the Ay'Cga uges.

Internal Failure of the SRS Unit
NOTE: Before troubleshooting any of these DTCs, check
the battery/system voltage. lf the voltage is low, repair
the charging system or replace the battery before
troubleshooting the SRS. lf the battery/system voltage
is now OK, ask the customer if the battery ever went
oeao,
1. Erase the DTC memory (see page 23-26).
2. Turn the ignition switch ON (ll), and check that the
SRS indicator comes on for about 6 seconds and
then goes off.
Does the SRS indicatot stay on?
YES Replace the SRS unit (see page 23-122).1
NO Intermittent failure, system is OK at this time.
Go to Troubleshooting lntermittent Failures (see
