CONSULT-II CHECKING SYSTEMPFP:00000
DescriptionEAS000G8

CONSULT-II is a hand-held type tester. When it is connected with a diagnostic connector equipped on the
vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various
kinds of diagnostic tests.

Refer to “CONSULT-II Software Operation Manual” for more information.
Function and System Application EAS000G9
x: Applicable
*1: Nissan Anti-Theft System
*2: Gasoline engine models
Nickel Metal Hydride Battery Replacement EAS000GA
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with Genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if
mistreated. Do not recharge, disassemble or dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.

Service Procedure
PERSONAL AUDIO SETTILNG
Description

The radio is designed to store several settings (volume, bass, treble, preset stations ) with every NATS
ignition key used. Up to a maximum of 4 NATS keys can be registered. During the communication men-
tioned under “Anti-Theft System”, the radio will recognize the used ignition key and select the accompany-
ing settings.
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 to NEW state by
authorized representative of radio manu-
facturer.—
Replacement of IMMU Radio needs to be reset to NEW state by
authorized representative of Clarion.After switching on the radio, it will display
“SECURE” after 1 minute.
No communication from IMMU to radio 1. If NATS is malfunctioning, check NATS
system.
2. After NATS is repaired, reset radio to
NEW state by authorized representative
of Clarion.After switching on the radio, the radio will
display “SECURE” after 1 minute. Further
use of radio is impossible until communica-
tion is established again, or after radio is
reset by authorized representative of Clar-
ion.
When initialized between ECM and IMMU. Radio needs to be reset to NEW status by
authorized representative of Clarion.After switching on the radio, it will display
“SECURE” after 1 minute.
