Operation
1. “AUTO TRIG”
●While trying to detect the DTC/1st trip DTC by performing the “DTC Confirmation Procedure”, be sure
to select to “DATA MONITOR (AUTO TRIG)” mode. You can confirm the malfunction at the moment it is
detected.
●While narrowing down the possible causes, CONSULT-II should be set in “DATA MONITOR (AUTO
TRIG)” mode, especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twisting) the suspicious connectors, compo-
nents and harness in the “DTC Confirmation Procedure”, the moment a malfunction is found the DTC/
1st trip DTC will be displayed. (Refer to “Incident Simulation Tests” in GI-23.)
2. “MANU TRIG”
●If the malfunction is displayed as soon as “DATA MONITOR” is selected, reset CONSULT-II to “MANU
TRIG”. By selecting “MANU TRIG” you can monitor and store the data. The data can be utilized for fur-
ther diagnosis, such as a comparison with the value for the normal operating condition.

SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to an
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2″-16
ACME.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale every three months.
To calibrate the weight scale on the ACR4:
1. Press Shift/Reset and Enter at the same time.
2. Press 8787 . “A1 ” will be displayed.
3. Remove all weight from the scale.
4. Press 0 , then press Enter . “0.00 ” will be displayed and change to “A2 ”.
5. Place a known weight (dumbbell or similar weight), between 4.5 and 8.6 kg (10 and 19 lb) on the center of
the weight scale.
6. Enter the known weight using four digits. (Example 10 lb = 10.00, 10.5 lb = 10.50)
7. Press Enter — the display returns to the vacuum mode.
8. Press Shift/Reset and Enter at the same time.
9. Press 6 — the known weight on the scale is displayed.
10. Remove the known weight from the scale. “0.00 ” will be displayed.
11 . P r e s s Shift/Reset to return the ACR4 to the program mode.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder′s top valve
when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Precautions for Leak Detection DyeEJS001YW
●The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
●Always wear fluorescence enhancing UV safety glasses to protect your eyes and enhance the visibility of
the fluorescent dye.
●The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to (J-
41995) pin-point refrigerant leaks.
●For your safety and your Customer′s satisfaction, read and follow all manufacture′s operating instructions
and precautions prior to performing the work.

NATS AUDIO LINKNJEL0497S12DescriptionNJEL0497S1201The link with the NATS IMMU implies that the audio unit can basically only beoperated if connected to the
matching NATS IMMU to which the audio unit was initially fitted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted theft of the audio unit is basically
useless since special equipment is required to reset the audio unit.
Initialization process for audio units that are linked to the NATS IMMU
Perform initialization with CONSULT-II
For initialization, refer to “CONSULT-II operation manual NATS”.
Normal operation
Each time the audio unit is switched on afterwards, the audio unit code willbe verified between the audio unit
and the NATS before the audio unit becomes operational.
When the radio is locked
When NATS link problems occur “SECURE” message will be displayed in three ways indicating three differ-
ent NATS link problems.
“Secure” on a red background indicates that there is a problem in the link between Navi control unit and Audio,
suggesting that there is either a Navigation system fault or the Navi control unit has previously been fitted in
another vehicle.
“Secure” on a green background indicates that there is a problem in the linkbetween NATS IMMU and Audio,
suggesting that there is an audio fault or the audio unit has previously been fitted in another vehicle.
“Secure” on a yellow background indicates that the transponder (NATS key)is not working correctly or it has
previously been fitted in another vehicle.
When a “Secure” message (of any type) is displayed, it can be cleared by re-initializing the NATS system using
CONSULT-II and the associated Immobilizer PIN code (there is no need to return the audio to a Clarion ser-
vice centre). If re-initializing fails to clear a “Secure” message then the component (identified by background
color) is faulty and should be replaced.
NOTE:
When the “Secure” is displayed on VFD display or audio unit, the communication of IMMU and radio, radio
unit or transponder has problem.
Service ProcedureNJEL0497S1202
Item Service procedure Description
Battery disconnection No additional action required. —
Radio needs repair Repair needs to be done by authorized
representative of radio manufacturer since
radio cannot be operated unless it is reset
to NEW state, using special decoding
equipment.—
Replacement of radio by new part No additional action required. Radio is delivered in NEW state.
Transferring radio to another vehicle/
replacement of radio by an “old” partRadio needs to be reset by using CON-
SULT-II and the associated Immobi PIN
code (there is no need to return the audio
or Navi units to a Clarion service centre).—
Replacement of IMMU The communication between IMMU and
radio need to be reset by using CON-
SULT-II and the associated Immobi PIN
code.After switching on the radio, it will display
“SECURE” on a green background.
No communication from IMMU to radio 1. If NATS is malfunctioning, check NATS
system.
2. After NATS is repaired, reset radio to
“Secure” on a green background state
by using CONSULT-II and the associ-
ated Immobilizer PIN code (there is no
need to return the audio to a Clarion
service centre).After switching on the radio, the display
unit will display “SECURE” on a green
background. Further use of radio is
impossible until communication is estab-
lished again, or after radio is reset by
using CONSULT-II and the associated
Immobilizer PIN code (there is no need to
return the audio to a Clarion service cen-
tre).

Trouble Diagnoses Introduction=NJRS0043CAUTION:
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow harness connector.
Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.
Keep ground portion clean.
DIAGNOSIS FUNCTIONNJRS0043S01The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II. The read-
ing of these results is accomplished using one of two modes — “User mode” and“Diagnosis mode”.
The User mode is exclusively prepared for the customer (driver). This modewarns the driver of a system
malfunction through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:
User mode Diagnosis mode Display type
“AIR BAG” warning lamp X X ON-OFF operation
CONSULT-II — X Monitoring
NOTE:
Seat belt pre-tensioner malfunction is indicated by “AIR BAG” warning lamp.
DIAGNOSIS MODE FOR CONSULT-IINJRS0043S02“SELF-DIAG [CURRENT]”
A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring
repairs.
“SELF-DIAG [PAST]”
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.
“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-II screen.
“ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber. This number will be displayed on the CONSULT-II screen, as shown below. When replacing the diag-
nosis sensor unit, refer to the part number for the compatibility. After installation, replacement with a cor-
rect unit can be checked by confirming this classification number on the CONSULT-II screen.
For NISSAN MODEL N16, the diagnosis sensor unit classification numbers are as follows:
