      ID 2 Tire Inflation Pressure ID2 tire inflation pressure min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2 , 0 psi), Relative pressure (Gauge) / 0 kPa (0 kgf/cm2 , 0 psi)
      max.: Absolute pressure (abs) / 488.72 kPa (4.9 kgf/cm2 , 70 psi), Relative pressure (Gauge) / 388.72kPa (3.9 kgf/cm2 , 56 psi)      		 Actual tire inflation pressure If N/A is displayed, data has not been received.*
      ID 3 Tire Inflation Pressure ID3 tire inflation pressure min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2 , 0 psi), Relative pressure (Gauge) / 0 kPa (0 kgf/cm2 , 0 psi)
      max.: Absolute pressure (abs) / 488.72 kPa (4.9 kgf/cm2 , 70 psi), Relative pressure (Gauge) / 388.72kPa (3.9 kgf/cm2 , 56 psi)      		 Actual tire inflation pressure If N/A is displayed, data has not been received.*
      ID 4 Tire Inflation Pressure ID4 tire inflation pressure min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2 , 0 psi), Relative pressure (Gauge) / 0 kPa (0 kgf/cm2 , 0 psi)
      max.: Absolute pressure (abs) / 488.72 kPa (4.9 kgf/cm2 , 70 psi), Relative pressure (Gauge) / 388.72kPa (3.9 kgf/cm2 , 56 psi)      		 Actual tire inflation pressure If N/A is displayed, data has not been received.*

      max.: Absolute pressure (abs) / 488.72 kPa (4.9 kgf/cm2 , 70 psi), Relative pressure (Gauge) / 388.72kPa (3.9 kgf/cm2 , 56 psi)      		 Actual tire inflation pressure
      • If N/A is displayed, data has not been received.*
      • w/ Full Size Spare Tire

      HINT: 

      • *: It may take a few minutes until the values are displayed.
      • When no "ID Tire Inflation Pressure" data has changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270 degrees. Then rapidly release the tire pressure and recheck the data.

      Chassis > Tire Pressure Monitor > Data List 

      Tester Display
      ID 1 Tire Inflation Pressure
      ID 2 Tire Inflation Pressure
      ID 3 Tire Inflation Pressure
      ID 4 Tire Inflation Pressure
      ID 5 Tire Inflation Pressure

    Result: 

    All tire pressure readings are equal to specified values. 

    END 

    Result: 

    Tire pressure values are not displayed.
