NOTE:
 Do not reuse the drained fluid. Use only clean Honda DOT 3 Brake Fluid from an unopened container.
Using a non-Honda brake fluid can cause corrosion
and shorten the life of the system.
 Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
 Do not spill brake fluid on the vehicle, it may damage the paint; if brake fluid does contact the paint, wash it
off immediately with water.
 The reservoir connected the master cylinder must be at the MAX (upper) l evel mark at the start of the
bleeding procedure, and checked after bleeding each
wheel location. Add fluid as required.
1. Make sure the brake fluid level in the reservoir (A) is at the MAX (upper) l evel line (B).
2. Have someone slowly pump the brake pedal several times, then apply steady pressure.
3. Start the bleeding at the driver’s side of the front brake system.
NOTE: Bleed the calipers in the sequence shown. 4. Attach a length of clear drain tube (A) to the bleed
screw (B), then loosen the bleed screw to allow air
to escape from the system. Then tighten the bleed
screw securely.
5. Refill the master cylinder reservoir to the MAX (upper) l evel line.
6. Repeat the procedure for each brake circuit until there are no air bubbles in the fluid.

Warm air comes out of
the vents, and there is
frost on the expansion
valve
Probable cause: The expansion valve is stuck
closed
Replace the expansion valve (see page 21-80)
HVAC DTCs (see page 21-9)
Check the old expansion valve
for contamination. If
contaminants are found,
replace the A/C system
component that caused the
contamination
The temperature of the
liquid line is the same
on both sides of the
expansion valve, and
the evaporator coil or
suction line has heavy
condensation Probable cause: The expansion valve is stuck
open
Replace the expansion valve (see page 21-80)
HVAC DTCs (see page 21-9)
Check the old expansion valve
for contamination. If
contaminants are found,
replace the A/C system
component that caused the
contamination
Warm air comes out of
the vents, but
operation is normal
otherwise Probable cause: Compressor failure
Do the A/C system test (see page 21-99), and
correct any problems. If necessary, replace the
compressor (see page 21-83) HVAC DTCs (see page 21-9)
Add refrigerant oil depending
on the part you replaced
(see page 21-7)
Driver’s and
passenger’s side vent
temperatures vary by
more than 11 °C (20 °F) Probable causes: The recirculation control door
or the air mix door is malfunctioning
Do the following troubleshooting:
Recirculation control motor test (see page
21-74)
Air mix control motor test (see page 21-72) HVAC DTCs (see page 21-9)
Poor or loose connections at the
terminals
Insufficient heating 1. 2.

7.Check the coolant level (see page 10-7)
Check the radiator cap (see page 10-4)
Check the coolant temperature during normal
operation
Check the heater core inlet hose temperature:
If it is COLD, check for restrictions in the hose,
a damaged or leaking thermostat, or a
damaged or leaking water pump
If it is HOT, check for restrictions in the
heater core. Back flush or replace the heater
core
Do the air mix control motor test (see page
21-72)
Check the blower motor unit for obstructions
Check for air leaks around the ducts and vents HVAC DTCs (see page 21-9)

Special Tools Required
Leak Detector Usage Tips (Refer to the
Operator’s Manual for complete operating
instructions)
21-93
Refrigerant Leak Check
 Leak detector YGK-H-10PM
 Leak detector HLD-100
 Leak detector TIFZX-1, or commercially available
 OPTIMAX Jr. A/C Leak Detection Kit (TRP124893)
These tools are available through the Honda Tool and
Equipment Program; call
888-424-6857
 Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat.
 Be careful when connecting service equipment.
 Do not breathe refrigerant or vapor.
NOTE:  If accidental system discharge occurs, ventilate the work area before resuming service.
 Additional health and safety information may be obtained from the refrigerant and lubricant
manufacturers.
 Check the system for leaks using an R-134a refrigerant leak detector with an accuracy of 14 g
(0.5 oz) per year or better.  Position the vehicle in a wind-free work area. This will
aid in detecting small leaks.
 When using the leak detector for the first time, allow it to warm up for 2 minutes with the probe in a clean
atmosphere. This lets the temperature sensor in the
detector stabilize.
 The calibration check should be done in the ‘‘Search 2’’ mode. Once that is done, the other check
modes do not need calibrating.
 When leak checking through the HVAC module drain hose, avoid drawing water into the probe. Water can
damage the internal pump and sensor.
 Avoid creasing the flexible probe extension. Creases can restrict air flow and give false readings.
 Because the detector recalibrates itself for ambient gases, it may be necessary to move the detector
away from the leak to clear the sensor. Once the
sensor has cleared, recheck the suspected leak.
 When removing the clear probe tip, be careful not to lose the flow ball.
 R-134a is heavier than air; always check below and to the sides of all potential leak sources.
 Halogen leak detectors are sensitive to chemicals: windshield washing solutions, solvents/cleaners, and
some vehicle adhesives. Keep these chemicals out of
the area when doing leak detection.
