Moving the electronic leak detector probe slower
and closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak Detector INFOID:0000000004307101
1. Check A/C system for leaks using the UV lamp and safety goggles J-42220 in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluoresc ent dye observed at the evaporator drain opening indi-
cates an evaporator core assembly (tubes , core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner J-43872 to prevent future misdiag- nosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and oils, may falsely trigger the l eak detector. Make sure the surfaces to be checked are
clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.
Dye Injection INFOID:0000000004307102
(This procedure is only necessary when recharging t he system or when the compressor has seized and was
replaced.)
1. Check A/C system static (at rest) pressure. Pres sure must be at least 345 kPa (3.45 bar, 3.52 kg/cm2
, 50
psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool J-41459.
3. Connect the injector tool to the A/C low-pressure side service fitting.
4. Start engine and switch A/C ON.
5. When the A/C operating (compressor running), inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye
through the low-pressure service valve using dye inje ctor tool J-41459 (refer to the manufacture’s operat-
ing instructions).
6. With the engine still running, disconnect the injector tool from the service fitting.
CAUTION:
Be careful the A/C system or replacing a componen t, pour the dye directly into the open system
connection and proceed wi th the service procedures.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the
leak size, operating conditions and location of the leak , it may take from minutes to days for the dye to
penetrate a leak and become visible.
Electronic Refrigerant Leak Detector INFOID:0000000004307103
PRECAUTIONS FOR HANDLING LEAK DETECTOR When performing a refrigerant leak c heck, use an A/C electrical leak
detector (SST) or equivalent. Ensure that the instrument is calibrated
and set properly per the operating instructions.
The leak detector is a delicate device. In order to use the leak detec-
tor properly, read the operating instructions and perform any speci-
fied maintenance. AHA281A

Fuse
INFOID:0000000004306651
• If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse.
• Use fuse of specified rating. Never use fuse of more than specified
rating.
• Do not partially install fuse; always insert it into fuse holder prop- erly.
• Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible Link INFOID:0000000004306652
A melted fusible link can be detected either by visual inspection or by
feeling with finger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION:
• If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted. In
such a case, carefully check and eliminate cause of malfunc-
tion.
• Never wrap outside of fusible li nk with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl or
rubber parts.
Circuit Breaker (B uilt Into BCM) INFOID:0000000004306653
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:
• Power windows
• Power sunroof
Circuit Breaker INFOID:0000000004306654
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of t he thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise shar ply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume. LKIA0830E

IPDM E/R STATUS CONTROL
In order to save power, IPDM E/R switches status by itself based on each operating condition.
1. CAN communication status • CAN communication is normally performed with other control units.
• Individual unit control by IPDM E/R is normally performed.
• When sleep request signal is received from BCM, mode is switched to sleep waiting status.
2. Sleep waiting status • Process to stop CAN communication is activated.
• All systems controlled by IPDM E/R are stopped. When 1 second has elapsed after CAN communica-
tion with other control units is st opped, mode switches to sleep status.
3. Sleep status • IPDM E/R operates in low current-consumption mode.
• CAN communication is stopped.
• When a change in CAN communication signal is detec ted, mode switches to CAN communication sta-
tus.
• When a change in ignition switch signal is detect ed, mode switches to CAN communication status.
CAN Communication System Description INFOID:0000000004306656
Refer to LAN-8, " System Diagram " .
Function of Detecting Ig nition Relay Malfunction INFOID:0000000004306657
• When the integrated ignition relay is stuck in a "clo sed contact" position and cannot be turned OFF, IPDM E/
R turns ON tail and parking lamps for 10 mi nutes to indicate IPDM E/R malfunction.
• When the state of the integrated ignition relay does not agree with the state of the ignition switch signal
received via CAN communication, the IPDM E/R activates the tail lamp relay.
NOTE:
When the ignition switch is turned ON, the tail lamps are OFF.
