substitute a known-good VSA modulator-control
unit (see page 19-171), and retest.
Repair open in the wire between the ECM/
PCM and the VSA modulator-control unit. 1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Test-drive the vehicle at 10 km/h (7 mph) or more.
NOTE: Drive the vehicle on the road, not on a lift.
4. Check for DTCs with the HDS.
If DTC 86-01 is indicated at the same time, do
the DTC 86-01 troubleshooting first (see page
19-156). If DTC 86-01 is not indicated, go to step 5.
If any other DTCs are indicated, go to the
indicated DTCs troubleshooting. If DTCs are not
indicated, there was an intermittent failure, the
system is OK at this time. Check for loose terminals
between ECM/PCM connector A (44P) and the VSA
modulator-control unit 37P connector. Refer to
intermittent failures troubleshooting (see page
19-98).

Installation
19-172VSA System Components
VSA Modulator-Control Unit Removal and Installation (cont’d)
1. Install the VSA modulator-control unit onto the bracket.
2. Install the bracket with the VSA modulator-control unit to the body.
3. Reconnect the six brake lines, then tighten the flare nuts to the specified torque.
4. Align the connecting surface of the VSA modulator-control unit 37P connector to the VSA modulator-control unit.
5. Pull up the lever of the VSA m
odulator-control unit 37P connector, then confirm the connector is fully seated.
6. Bleed the brake system (see page 19-9).
7. Do the VSA sensor neutral position memorization (see page 19-169).
8. Start the engine, and make sure the ABS and the VSA indicators go off.
9. Test-drive the vehicle, and make sure the ABS, and the VSA indicators do not come on. NOTE: If the brake pedal is spongy, there may be air trapped in the modulator which could then be induced into
the normal brake system during modulation. Bleed the brake system again (see page 19-9).

4. Apply multi-purpose grease to the wheel speedsensor O-ring (A) and the sensor hole in the knuckle
(B).
5. Insert the guide pin tool (A) into the wheel speed sensor bolt hole until the shoulder of the tool
contacts the wheel speed sensor bracket.
NOTE: To prevent O-ring damage, the wheel speed
sensor must be installed with the guide pin tool. 6. Insert the wheel speed sensor (A) and the guide pin
tool (B) into the bolt hole on the knuckle.
NOTE: To ensure proper alignment when pushing
the wheel speed sensor into the knuckle housing,
do not hold the sensor bracket during installation,
hold the sensor wire.
7. Gently push and pull the wheel speed sensor in and out to make sure the O-ring is sliding properly in its
housing. While you are doing this, make sure the
sensor doesn’t come out of the knuckle assembly. If
the sliding effort is too high, remove the wheel
speed sensor, inspect the O-ring for damage, and
start the installation process again.
8. Remove the guide pin tool, then install the bolt, and tighten it to specified torque.
9. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the front
wheel.
10. Start the engine, and make sure the ABS and the VSA indicators go off.
11. Test-drive the vehicle, and make sure the ABS and the VSA indicators do not come on.

A/C Refrigerant Oil Replacement

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)
Evaporator .40 mL (1 1/3 fl·oz)
Line or hose .10 mL (1/3 fl·oz)
Receiver/Dryer .10 mL (1/3 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.
