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
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.

PRECAUTIONS
[4WD/ABS]PRECAUTIONSPFP:00001
Precautions for brake systemEFS001B6
●Recommended fluid is brake fluid “DOT 3 ”or “DOT 4”.
●Never reuse drained brake fluid.
●Be careful not to splash brake fluid on painted areas.
●To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.
●Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
●Use flare nut wrench when removing and installing brake tube.
●Always torque brake lines when installing.
●Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage. Refer to BR-10, "
Brake Burnishing
Procedure" .
●Before working, turn OFF ignition switch. Disconnect connectors
for ABS actuator and control module or battery terminals.
WARNING:
●Clean brake pads and shoes with a waste cloth, then wipe
with a dust collector.
Precautions for brake controlEFS001B7
●If malfunction is indicated by 4WD warning lamp and/or ABS warning lamp, collect necessary information
from customer (what symptoms are present under what conditions). Find out possible causes before start-
ing service. Besides electrical system inspection, check operation of ABS actuator.
●If malfunction is detected, proceed to trouble diagnosis after checking tire pressure and tire wear.
●Stopping distance or steering stability may be deteriorated by the following conditions. Tire size and type
are in improper combination. Brake pads are not Nissan genuine parts.
●Fitting tires of different size on vehicle can be cause of longitudinal vibration. Always use tires of the same
size and brand. Exchange front and rear tires on the following conditions: Longitudinal vibration occurs in
vehicle with tires of the same size and brand. After replacement, perform trouble diagnosis. 1580|None
●4WD/ABS function may have a failure or error under following condition: There is radio, antenna, or
antenna lead-in wire (including wiring) near control module.
●If aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check electrical har-
nesses for pinches, open, and improper wiring.
