AV Switch Self-Diagnosis FunctionEKS00BIF
It can check ON/OFF operation of each switch in the AV switch and diagnose the input signals from the steer-
ing switch.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “PAUSE/MUTE”
and “PREV” simultaneously for 3 seconds.
Then the self-diagnosis operates. A single beep indicates self-
diagnosis mode is active.
3. Press each switch and listen for beep.
NOTE:
CD player LOAD and EJECT buttons are not included in this test
and will not beep when pressed.
EXITING THE SELF-DIAGNOSIS MODE
Turn ignition switch OFF. Then the self-diagnosis ends.
DIAGNOSIS FUNCTION
It can check for continuity of the switches by sounding the beep when each AV switch and steering switch
is pressed.
It can check for continuity of harness between AV switch and steering switch.

Precautions for Brake ControlEFS004X6
During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
Just after starting vehicle, the brake pedal may vibrate or a motor operating noise may be heard from
engine compartment. This is a normal status of operation check.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnosis. Besides electrical system inspection, check booster operation, brake fluid level, and fluid leaks.
If incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
If there is a radio, antenna or related wiring near control module, ABS function may have a malfunction or
error.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits or improper wiring.
If the following components are replaced with non-genuine components or modified, the VDC OFF indica-
tor lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorbers, struts, springs, bushings, etc.), tires, wheels (exclude specified
size), components related to brake system (pads, rotors, calipers, etc.), components related to engine
(muffler, ECM, etc.), components related to body reinforcement (roll bar, tower bar, etc.).
Driving with broken or excessively worn suspension components, tires or brake system components may
cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC system may not
operate properly.
When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.
When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp curves on a freeway), the VDC may not operate normally, or the VDC warning lamp and the SLIP
indicator lamp may turn on. This is not a problem if normal operation can be resumed after restarting the
engine.
Sudden turns (such as spin turns, acceleration turns), drifting, etc. with VDC turned off may cause the yaw
rate/side G sensor to indicate a problem. This is not a problem if normal operation can be resumed after
restarting the engine.
Precautions for CAN SystemEFS004X7
Do not apply voltage of 7.0V or higher to terminal to be measured.
Maximum open terminal voltage of tester in use must be less than 7.0V.
Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.

ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU of the IPDM E/R controls the tail lamp relay coil, which, when
energized, directs power
