CONSULT-II Function (METER A/C AMP)AKS005NB
CONSULT-II performs the following functions communicating with the unified meter and A/C amp.
CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect “CONSULT-II” and “CON- SULT-II CONVERTER” to the data link connector, then turn igni-
tion switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “METER A/C AMP” on “SELECT SYSTEM” screen. If “METER A/C AMP” is not indicated, go to GI-39, "
CONSULT-II
Data Link Connector (DLC) Circuit" .
4. Select “SELF-DIAG RESULTS”, “CAN DIAG SUPPORT MNTR” or “DATA MONITOR”.

SELF-DIAGNOSTIC RESULTS
Operation Procedure
1. Touch “SELF-DIAG RESULTS” on “SELECT DIAG MODE” screen.
2. Self-diagnosis results are displayed.
Display Item List
“TIME” indicates the condition of the self-diagnostic results judged by each signal input.

Normal: In case of operating properly at the present in spite of having malfunction in the past, then “TIME”
indicates “1-63”.

Malfunction: Soon after detecting malfunctions by self-diagnoses or current malfunction, “0” is indicated.
After returning to normal condition, every time when ignition switch is turned to “OFF” from “ON”, time will be
added like “1” →“2” →“3”···“63”, and when the key operation is performed 64 times, the result of the self-diag-
noses will be erased. And if any malfunction is detected again, “0” will be indicated.
CAUTION:
“TIME” keeps showing “0” after returning to normal condition only in the case that malfunction his-
tory of “CAN COMM CIRC [U1000]” remains because of low tire pressure warning control unit, display
control unit (with NAVI) or display unit (without NAVI) malfunction.
DATA MONITOR
Operation Procedure
1. Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.
2. Touch either “MAIN SIGNALS” or “SELECTION FROM MENU” on the “DATA MONITOR” screen.
3. When “SELECTION FROM MENU” is selected, touch individual items to be monitored. When “MAIN SIG- NALS” is selected, main items will be monitored.

CAUTION:
Even when there is no malfunction on CAN communication system, malfunction
may be misinterpreted when battery has low voltage (when maintaining 7 - 8 V
for about 2 seconds) or 10A fuse [No. 19, located in the fuse block (J/B)] is dis-
connected. DI-34

COMPASS
Revision: 2005 July 2005 FX
COMPASSPFP:24835
System DescriptionAKS007AO
This unit displays earth magnetism and heading direction of vehicle.
DIRECTION DISPLAY
Push the switch when the ignition key is in the “ON” or “START” position. The direction will be displayed.
Pushing the “COMP” switch a second time will turn off the display.
1. If the display reads “C” calibrate the compass by driving the vehicle in 3 complete circles at less than 8 km/h (5 MPH).
2. To adjust for compass variance:
a. Press the “COMP” switch for more than 3 seconds. The current zone number will appear in the display.
b. Find your current location and variance zone number on the zone map.
c. Press the “COMP” switch until the new zone number appears in the display. After you stop pressing the button in, the display will show a compass direction within a few seconds.
NOTE:
1. Do not install the ski rack, antenna, etc. which are attached to the vehicle by means of a magnet. They affect the operation of the compass.
2. If the compass deviates from the correct indication soon after repeated adjustment, have the compass checked at an authorized dealer.
3. The compass may not indicate the correct compass point in tunnels or while driving up or down a steep hill. (The compass returns to the correct compass point when the vehicle moves to an area where the
geomagnetism is stabilized.)
3. Cleaning the Mirror When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not
spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing.
“C” is displayed in the compass window.
