P0500 VSS
DescriptionINFOID:0000000003856685
The vehicle speed signal is sent to the combination meter from the “ABS actuator and electric unit (control
unit)” by CAN communication line. The combination meter then sends a signal to the ECM by CAN communi-
cation line.
DTC LogicINFOID:0000000003856686

DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Will CONSULT-III be used?
Will CONSULT-III be used?
YES >> GO TO 2.
NO >> GO TO 5.
2.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
>> GO TO 3.
3.CHECK VEHICLE SPEED SIGNAL
NOTE:
This procedure may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.
With CONSULT-III
1. Start engine (VDC switch OFF).
2. Read “VHCL SPEED SE” in “DATA MONITOR” mode with CONSULT-III. The vehicle speed on CON-
SULT-III should exceed 10 km/h (6 MPH) when rotating wheels with suitable gear position.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Go to EC-235, "
Diagnosis Procedure".
4.PERFORM DTC CONFIRMATION PROCEDURE
1. Select “DATA MONITOR” mode with CONSULT-III.
2. Warm engine up to normal operating temperature.
3. Maintain the following conditions for at least 50 consecutive seconds.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003814141
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the “SRS AIRBAG” and
“SEAT BELT” of this Service Manual.
WARNING:
 To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
ServiceINFOID:0000000003814109
 Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
 Before servicing the SRS, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3
minutes.
For approximately 3 minutes after the battery negative terminal is removed, it is still possible for the air bag
and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3
minutes have elapsed.
 Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installa-
tion and replace as required.
 The spiral cable must be aligned in the neutral position since its rotations are limited. Do not turn steering
wheel and column after removal of steering gear.
 Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side
facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.
 Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
 After air bag inflates, the front instrument panel assembly should be replaced if damaged.
 Always replace instrument panel pad following front passenger air bag deployment.

Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003806307
NOTE:
 Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.
Service Notice or Precautions for Steering SystemINFOID:0000000003806308
CAUTION:
 In case of removing steering gear assembly, make the final tightening with grounded and unloaded
vehicle condition, and then check wheel alignment.
 Observe the following precautions when disassembling.
- Before disassembly, thoroughly clean the outside of the unit.
- Disassembly should be done in a clean work area. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
