NOTE: Keep all foreign particles out of the transmission. 1. Park the vehicle on the level ground.
2. Warm up the engine to normal operating temperature (the radiator fan comes on), and turn
the engine off.
3. Remove the drain plug (A), and drain the automatic transmission fluid (ATF).
4. Reinstall the drain plug with a new sealing washer (B).
5. Refill the transmission with ATF into the dipstick hole to bring the fluid level between the upper
mark and the lower mark of the dipstick. Always
use Acura ATF-Z1 automatic transmission fluid
(ATF). Using a non-Acura ATF can affect shift
quality.
6. Check that the ATF level is between the upper mark
and the lower mark of the dipstick.
7. Insert the dipstick back into the transmission with the letters ‘‘ATF’’ pointing toward the front of the
vehicle. 8. If the maintenance minder required to replace the
ATF, reset the maintenance minder (see page 3-4),
and this procedure is complete. If the maintenance
minder did not require you to replace the ATF, go
to step 9.
9. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
10. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
11. Select BODY ELECTRICAL with the HDS.
12. Select ADJUSTMENT in the GAUGES MENU with the HDS.
13. Select RESET in the MAINTENANCE MINDER MENU with the HDS.
14. Select RESETTING THE ATF with the HDS.
NOTE: If you changed the engine oil at the same
time with the ATF, select RESETTING THE ENGINE
OIL LIFE AND ATF with the HDS instead.
Replace.

Brake System Test
19-4 Conventional Brake Components
Brake System Inspection and Test
Inspect the brake system components listed. Repair or replace any parts that are leaking or damaged.










Master Cylinder Look for damage or signs of fluid leakage at:
Reservoir tank, subreservoir or master
cylinder body.
Lines, reservoir tank hose and grommets,
and their joints.
Between master cylinder and booster. Bulging seal at reservoir cap. This is a
sign of fluid contamination.
Brake Hoses Look for damage or signs of fluid leakage at: Line joints and banjo bolt connections.
Hoses and lines, also inspect for twisting or
damage. Bulging, twisted, or bent lines.
Caliper Look for damage or signs of fluid leakage at: Piston seal.
Banjo bolt connections.
Bleed screw. Seized or sticking caliper pins.
ABS or VSA
Modulator-control
Unit Look for damage or signs of fluid leakage at:
Line joints.
Modulator-control unit.
1. Set the parking brake, and start the engine, then turn off the A/C. Allow the engine to warm up to normal operating temperature (radiator fan comes on twice).
2. Attach a 50 mm (2 in.) piece of masking tape along the bottom of the steering wheel, and draw a horizontal reference mark across it.
3. With the transmission in neutral (M/T) or P or N (A/T), press and hold the brake pedal lightly (about the same pressure needed to keep an A/T-equipped vehicle from creeping), then release the parking brake.
4. While still holding the brake pedal, hook the end of the tape measure behind the brake pedal, then pull the tape up to the steering wheel. Note the measurement between the brake pedal and the reference mark on the steering
wheel.
5. Apply steady pressure to the brake pedal for 3 minutes.
6. Watch the tape measure.  If the measurement increases 10 mm (0.39 in.) or less, the master cylinder is OK.
 If the measurement increases more than 10 mm (0.39 in.), replace the master cylinder.

3. Inspect the drive belt (see page 4-30).
4. Make sure no material is blocking the air flow to the
A/C condenser.
5. Check the dust and pollen filter. Replace it if it is clogged (see page 21-75).
6. Check for kinks or sharp bends in the A/C lines and hoses, which can greatly reduce system
performance. Replace A/C lines and hoses if they
are kinked or damaged (see page 21-8).
7. Start the engine, turn the air conditioning system on, and allow it to run for a few minutes and reach
stable operation.
 Check that the A/C operates at each position of the blower fan switch (except OFF). If the A/C
does not operate, refer to the symptom
troubleshooting.
 Check that the A/C compressor clutch (A) is engaged. The pressure plate should be rotating
at the same speed as the pulley. If the pressure
plate does not engage, refer to the symptom
troubleshooting.
 Check that the A/C condenser fan (B) and radiator fan (C) operate when the A/C compressor clutch
is engaged. If either fan fails to operate when the
A/C compressor clutch is engaged, refer to the
symptom troubleshooting.
 Check that the engine idle speed is correctly maintained when the A/C is switched on and off
and the A/C compressor clutch is engaged and
disengaged. Recommended PAG oil: SP-10
P/N 38897-P13-A01AH: 120 mL (4 fl·oz)
It is important to have the correct amount of refrigerant
oil in the A/C system to ensure proper lubrication of the
compressor. Too little oil damages the compressor; too
much oil reduces the cooling capacity of the system,
and can produce high vent temperatures.
 To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other
refrigerant oils.
 Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture
absorption.
 Do not spill the refrigerant oil on the vehicle; it may damage the paint; if it gets on the paint, wash it off
immediately.
Add the recommended refrigerant oil in the amount
listed if you replace any of the following parts: ........
.............. ............ ........

A/C condenser .50 mL (1 2/3 fl·oz)

Leakage repair .25 mL (5/6 fl·oz)
A/C compressor .Since the oil separator is
equipped inside the compressor
for this vehicle, oil drainage is
unnecessary at the time of
compressor replacement.

7. Remove the mounting bolts and the A/C
compressor (A). Be careful not to damage the
radiator fins when removing the A/C compressor. 8. Install the compressor in the reverse order of
removal, and note these items:
 Inspect the A/C lines for any signs of contamination.
 If you’re installing a new A/C compressor, you must calculate the amount of refrigerant oil to be
removed from it (see page 21-7). A new A/C
compressor comes with a full charge of oil.
 Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before
installing them. Be sure to use the correct O-rings
for HFC-134a (R-134a) to avoid leakage.
 Use refrigerant oil (SP-10) for HFC-134a SANDEN spiral type A/C compressor only.
 To avoid contamination, do not return the oil to the container once dispensed, and never mix it
with other refrigerant oils.
 Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture
absorption.
 Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil
contacts the paint, wash it off immediately.
 Charge the system (see page 21-92).
