5. Disconnect one-touch joint between high-pressure pipe 1 and 2.
a. Set a disconnector (SST: 9253089908) on A/C piping.
b. Slide a disconnector toward vehicle rear until it clicks.
c. Slide A/C piping toward vehicle rear and disconnect it. CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air.
6. Remove high-pressure pipe 1.
7. Disconnect one-touch joint between high-pressure pipe 2 and 3.
a. Set a disconnector (SST: 9253089908) on A/C piping.
b. Slide a disconnector toward vehicle front until it clicks.
c. Slide A/C piping toward vehicle front and disconnect it.
8. Remove high-pressure pipe 2. CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace O-rings of high-pressure pipe with new ones, and then apply compressor oil to it when
installing it.

Connection point for female-side piping is thin. So, when inserting male-side piping, take care not
to deform female-side piping. Slowly insert in axial direction.

Insert one-touch joint connection point securely until it clicks.

After piping has been connected, pull male-side piping by hand to make sure piping does not
come off.

When recharging refrigerant, check for leaks.

REMOVAL
1. Set the temperature (passenger side) at 18 °C (60 °F), and then disconnect the battery cable from the neg-
ative terminal.
2. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
3. Remove cowl top cover. Refer to EI-23, "
COWL TOP" .
4. Remove mounting bolts from low-pressure pipe 1 bracket and low-pressure flexible hose bracket.

A/C and AV Switch Self-Diagnosis FunctionAKS007OE
It can check ON/OFF operation of each switch in the A/C and AV switch and diagnose the input signals to the
audio steering wheel switch.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “MUTE/ II ” and
“MAP ”simultaneously for 3 seconds.
Then the self-diagnosis operates.
EXITING THE SELF-DIAGNOSIS MODE

Turn ignition switch OFF. Then the self-diagnosis ends.
DIAGNOSIS FUNCTION

It can illuminate all the indicators (LED) in the A/C and AV switch.

It can check for continuity of the switches by sounding the buzzer when the A/C and AV switch is pressed.

It can check for continuity of harness between A/C and AV switch and audio steering wheel switch.

OK >> GO TO 2.
NG >> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to PG-
3, "POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Check voltage between the audio unit connector and ground.
2. Check voltage between BOSE speaker amp.connector or woofer connector and ground.
OK or NG
OK >>
INSPECTION END (Audio unit is OK.)

GO TO 3. (BOSE speaker amp. and woofer)
NG >> Repair harness or connector between each unit and fuse.

Locking CD Auto-Changer MechanismAKS007GD
CAUTION:

Prior to removing a malfunctioning CD auto-changer unit that will be shipped for repair, the
changer mechanism MUST BE LOCKED to prevent the mechanism from being damaged during
shipping.

If a CD is jammed or unable to be removed from the unit, do NOT lock the changer mechanism. If
the unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit.
2. Turn ignition switch OFF. Wait until audio unit display is off and mechanism stops moving (mechanism sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the audio unit, press the same disc selection button again within 5 seconds.

The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism sound stops), open the driver and passenger window, and then disconnect negative battery cable.
NOTE:
After installing a new or remanufactured audio unit, switching the audio unit ON will automatically unlock the
mechanism. A special unlocking procedure is not required.
