Diagnostic Trouble Code (DTC)

DTC Erasure

1. Pull the parking brake lever up.

2. Push and hold the TCS switch, then turn the ignition switch ON (II).

3. Hold the TCS switch pushed for four seconds (do not release the TCS switch), then release the TCS switch for less than

six seconds.

4. After three seconds, the TCS indicator light go off three times, then turn it on. It means that the DTC is erased.

NOTE:

• Follow these steps exactly. If you connect the SCS service connector and/or release the parking brake lever during

these steps, the DTC will not be erased.

• If the TCS indicator light blinks repeatedly, replace the TCS control unit.

A/C Service Tips and Precautions

The air
conditioner system uses
HFC-134a
(R-134a)
refrigerant
and
polyalkyleneglycol (PAG) refrigerant
oil*,
which
are not

compatible with CFC-12 (R-12) refrigerant and mineral oil. Do not use R-12 refrigerant or mineral oil in this system, and do

not attempt to use R-12 servicing equipment; damage to the air conditioner system or your servicing equipment will result.

*DENSO ND-OIL 8:

P/N 38897 - PR7 - A01AH: 120 (4 fl-oz, 4.2 Imp-oz)

P/N 38899 - PR7 - A01: 40 (1 1/3 fl-oz, 1.4 Imp-oz)

Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove R-134a

from the air conditioner system.

CAUTION: Exposure to air conditioner refrigerant and lubricant vapor or mist can irritate eyes, nose and throat. Avoid

breathing the air conditioner refrigerant and lubricant vapor or mist.

If accidental system discharge occurs, ventilate work area before resuming service.

R-134a service equipment or vehicle air conditioner systems should not be pressure tested or leak tested with compressed

air.

Some mixtures of air and R-134a have been shown to be combustible at elevated pressures and can result

in tire or explosion causing injury or property damage. Never use compressed air to pressure test R-134a service equip-

ment or vehicle air conditioner systems.

Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.

1. Always disconnect the negative cable from the battery whenever replacing air conditioning parts.

2. Keep moisture and dust out of the system. When disconnecting any lines, plug or cap the fittings immediately; don't

remove the caps or plugs until just before you reconnect each line.

3. Before connecting any hose or line, apply a few drops of refrigerant oil to the O-ring.

4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.

5. When discharging the system, use a R-134a refrigerant Recovery/Recycling/Charging System; don't release refriger-

ant into the atmosphere.

6. Add refrigerant oil after replacing the following parts:

NOTE:

To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refriger-

ant oils.

Immediately after using the oil, replace 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.

Compressor ................................ For compressor replacement, subtract the volume of oil drained from the

removed compressor from 140 (4 1/3 fl-oz, 4.9 Imp-oz), and drain the calculated

volume of oil from the new compressor: 140 (4 1/3 fl-oz, 4.9 Imp-oz) — Volume

of removed compressor = Volume to drain from new compressor.

NOTE: Even if no oil is drained from the removed compressor, don't drain more

than 50 (1 2/3 fl-oz, 1.8 Imp-oz) from the new compressor.

Performance Test

The performance test will help 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 system.

CAUTION: Exposure to air conditioner refrigerant and

lubricant vapor or mist can irritate eyes, nose and

throat. Avoid breathing the air conditioner refrigerant

and lubricant vapor or mist.

If accidental system discharge occurs, ventilate work

area before resuming service.

R-134a service equipment or vehicle air conditioner sys-

tems should not be pressure tested or leak tested with

compressed air.

Some mixtures of air and R-134a have been

shown to be combustible at elevated pressures and can

result in fire or explosion causing injury or property

damage. Never use compressed air to pressure test R-

134a service equipment or vehicle air conditioner sys-

tems.

Additional health and safety information may be obtained

from the refrigerant and lubricant manufacturers.

2.
Connect a R-134a refrigerant Recover/Recycling/

Charging System to the vehicle, as shown, follow-

ing the equipment manufacturer's instructions.

Insert a thermometer in the center vent outlet.

Determine the relative humidity and air tempera-

ture.

3. Test conditions:

Avoid direct sunlight.

Open hood.

Open front doors.

Set the temperature control dial on MAX COOL,

the mode control switch on VENT and the recir-

culation control switch on RECIRCULATE.

Turn the A/C switch on, and the fan switch on

4. After running the air conditioning for 10 minutes

under the above test conditions, read the delivery
