DIAGNOSIS SYSTEM (IPDM E/R)
Concept of auto active test
 IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
 The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.

gage room.)
NOTE:
Do not remove the temporary tire, jack and on-vehicle tool.
 Wipe out dirt on the headlamp.
CAUTION:
Never use organic solvent (thinner, gasoline etc.)
 Ride alone on the driver seat.
AIMING ADJUSTMENT SCREW
 Turn the aiming adjusting screw for adjustment.
 For the position and direction of the adjusting screw, refer to the

CAUTION:
Never cover the lens surface with a tape etc. The lens is made of resin.
NOTE:
Shut off the headlamp light with the board to prevent from illuminating the adjustment screen.

COMPRESSOR SYSTEM SYMPTOMS
Symptom TableINFOID:0000000003795808
Follow the next table and perform trouble diagnosis if there is a compressor unit malfunction (internal noise,
insufficient cooling).
*1: First conduct inspection according to trouble diagnosis for each malfunction. Refer to HAC-88, "
Inspection
procedure".
*2: Applicable to variable capacity compressor only.
Symptom Inspection method Check list Result Action
Noise from compressor unit
When A/C is ON.

ternal pressureCheck with manifold gaugeBoth high- and low-
pressure sides are
high.
*2

judge.
Refer to the criteria
shown in compressor

Diagnostic result 2:
Replace compressor
and liquid tank. Insufficient cooling

Compressor bodyCheck rotation of compressor.
If sized or stuck, sample com-
pressor oil and judge.
Cooler system inter-
nal pressureCheck with a manifold gauge.
Sample compressor oil and
judge if the difference between
high-pressure and low-pres-
sure is small or if they are al-
most the same.

WARNING:
Check that all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
Observe the following when replacing or cleaning refrigerant cycle components.
 Store it in the same way at it is when mounted on the car when the compressor is removed. Failure
to do so causes lubricant to enter the low-pressure chamber.
 Use always a torque wrench and a back-up wrench when connecting tubes.
 Plug immediately all openings to prevent entry of dust and moisture after disconnecting tubes.
 Connect the pipes at the final stage of the operation when installing an air conditioner in the vehicle.
Never remove the seal caps of pipes and other components until just before required for connection.
 Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
 Remove thoroughly moisture from the refrigeration system before charging the refrigerant.
 Replace always used O-rings.
 Apply lubricant to circle of the O-rings shown in illustration when connecting tube. Be careful not to
apply lubricant to threaded portion.
 O-ring must be closely attached to the groove portion of tube.
 Be careful not to damage O-ring and tube when replacing the O-ring.
 Connect tube until a click can be heard. Then tighten the nut or bolt by hand. Check that the O-ring is
installed to tube correctly.
