1.CHECK TIRE PRESSURE SIGNAL With CONSULT-III

1. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2. Within 5 minutes, select “DATA MONITOR” for the CONSULT-III “AIR PRESSURE MONITOR”.
3. Read the values that are displayed for “AIR PRESS FL”, “AIR PRESS FR”, “AIR PRESS RR”, and “AIR PRESS RL”.

   Display Item | Condition | Displayed value
   AIR PRESS FL | Drive for 3 minutes at a speed of 40 km/h (25MPH) or more, then drive normally for 10 minutes. | Internal pressure of tires
   AIR PRESS FR
   AIR PRESS RR
   AIR PRESS RL

Is the tire pressure of 0 kPa (Psi) displayed for all wheels?
YES>>GO TO 2.
NO>>GO TO 4.
2.CHECK HARNESS BETWEEN LOW TIRE PRESSURE WARNING CONTROL UNIT AND TIRE PRESSURE RECEIVER

1. Turn the ignition switch OFF.
2. Disconnect low tire pressure warning control unit harness connector and tire pressure receiver harness connector.
3. Check the continuity between low tire pressure warning control unit harness connector and tire pressure receiver harness connector.

Is the inspection result normal?
YES>>GO TO 3.
NO>>Repair or replace error-detected parts.
3.CHECK TIRE PRESSURE RECEIVER
Check the tire pressure receivers. Refer to Diagnosis Procedure (GT-R certified NISSAN dealer).
Is the inspection result normal?
YES>>GO TO 4.
NO>>Replace the receiver.
4.CHECK TIRE PRESSURE MONITORING CONTROL SYSTEM
Check the Tire Pressure Monitoring System (TPMS). Refer to Diagnosis Procedure (GT-R certified NISSAN dealer).
Is the inspection result normal?
YES>>GO TO 5.
NO>>Replace the low tire pressure warning control unit.
5.CHECK TRANSMITTERS

1. Drive for several minutes at a speed of 40 km/h (25 MPH) or more, then stop the vehicle.
2. Within 15 minutes, use “DATA MONITOR” to display the tire pressure for all wheels.
3. Check that the tire pressures is the specified value.

   Display Item | Condition | Displayed value
   AIR PRESS FL | Drive for several minutes at a speed of 40 km/h (25 MPH) or more, then stop the vehicle. | Internal pressure of tire pressure
   AIR PRESS FR
   AIR PRESS RR
   AIR PRESS RL

Is the inspection result normal?
YES>>INSPECTION END
NO>>Replace the transmitter.
