SERVICE COUPLERSNJHA0117S06Never 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 contamina-
tion may occur.

REFRIGERANT WEIGHT SCALENJHA0117S07Verify 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 1/2²-16
ACME.
CALIBRATING ACR4 WEIGHT SCALENJHA0117S09Calibrate the scale every three months.
To calibrate the weight scale on the ACR4:
1. PressShift/ResetandEnterat the same time.
2. Press8787.ªA1º will be displayed.
3. Remove all weight from the scale.
4. Press0, then pressEnter.ª0.00º will be displayed and change
to ªA2º.
5. Place a known weight (dumbbell or similar weight), between
4.5 and 36.3 kg (10 and 80 lb) on the center of the weight
scale.
6. Enter the known weight using four digits. (Example 10 lb =
ª10.00º, 10.5 lb = ª10.50º)
7. PressEnterÐ the display returns to the vacuum mode.
8. PressShift/ResetandEnterat the same time.
9. Press6Ð the known weight on the scale is displayed.
10. Remove the known weight from the scale. ª0.00º will be dis-
played.
11. PressShift/Resetto return the ACR4 to the program mode.
CHARGING CYLINDERNJHA0117S08Using 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.

Trouble Diagnoses IntroductionNJRS0043CAUTION:
+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 ªAIR BAGº warning lamp and/or CONSULT-II. The read-
ing of these results is accomplished using one of two modes Ð ªUser modeº and ªDiagnosis modeº.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction through the operation of the ªAIR BAGº warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the ªAIR BAGº warning lamp and CONSULT-II are as follows:
User mode Diagnosis mode Display type
ªAIR BAGº warning lamp X X ON-OFF operation
CONSULT-II Ð X Monitoring
NOTE:
Seat belt pre-tensioner malfunction is indicated by ªAIR BAGº warning lamp.

DIAGNOSIS MODE FOR CONSULT-II=NJRS0043S02+ªSELF-DIAG [CURRENT]º
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.
+ªSELF-DIAG [PAST]º
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.
+ªTROUBLE DIAG RECORDº
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on the CONSULT-II screen.
+ªECU DISCRIMINATED NO.º
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:
