DTC C2177/77: Initialization not Completed: Procedure

1. Check that the vehicle is not located in an area such as described below:
   1. Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.

      HINT: 

      If the vehicle is located in an area such as the one described above, the tire pressure warning light may come on after blinking 1 minute only in a particular area due to interfering radio frequencies.

   2. Devices using similar radio frequencies are used in the vehicle.

      OK

      Facilities, or devices that use similar radio frequencies are not located in the vicinity of the vehicle.

      HINT: 

      Radio transmissions may be interrupted due to the surroundings, or devices installed by the user.

NG → CHECK IF ANY DEVICE IS INSTALLED BY USER 

OK: Go to next step 

1. Perform initialization. Refer to INITIALIZATION .

NEXT: Go to next step 

1. Turn the ignition switch off.
2. Connect the Techstream to the DLC3.
3. Turn the ignition switch to ON.
4. Turn the Techstream on.
5. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
6. Check the values by referring to the table below.

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   ID1 Tire Inflation Pressure	ID1 tire inflation pressure/ min.: Absolute pressure / 50 kPa (0.5 kgf/cm2 , 7 psi), Relative pressure / -50 kPa (-0.5 kgf/cm2 , -7 psi) max.: Absolute pressure / 480 kPa (4.9 kgf/cm2 , 70 psi), Relative pressure / 380 kPa (3.9 kgf/cm2 , 55 psi)	Actual tire inflation pressure	If 50 kPa (0.5 kgf/cm2 , 7 psi) is displayed for absolute pressure or -50 kPa (-0.5 kgf/cm2 , -7 psi) is displayed for relative pressure, data has not been received.*
   ID2 Tire Inflation Pressure	ID2 tire inflation pressure / min.: Absolute pressure / 50 kPa (0.5 kgf/cm2 , 7 psi), Relative pressure / -50 kPa (-0.5 kgf/cm2 , -7 psi) max.: Absolute pressure / 480 kPa (4.9 kgf/cm2 , 70 psi), Relative pressure / 380 kPa (3.9 kgf/cm2 , 55 psi)	Actual tire inflation pressure	If 50 kPa (0.5 kgf/cm2 , 7 psi) is displayed for absolute pressure or -50 kPa (-0.5 kgf/cm2 , -7 psi) is displayed for relative pressure, data has not been received.*
   ID3 Tire Inflation Pressure	ID3 tire inflation pressure / min.: Absolute pressure / 50 kPa (0.5 kgf/cm2 , 7 psi), Relative pressure / -50 kPa (-0.5 kgf/cm2 , -7 psi) max.: Absolute pressure / 480 kPa (4.9 kgf/cm2 , 70 psi), Relative pressure / 380 kPa (3.9 kgf/cm2 , 55 psi)	Actual tire inflation pressure	If 50 kPa (0.5 kgf/cm2 , 7 psi) is displayed for absolute pressure or -50 kPa (-0.5 kgf/cm2 , -7 psi) is displayed for relative pressure, data has not been received.*
   ID4 Tire Inflation Pressure	ID4 tire inflation pressure / min.: Absolute pressure / 50 kPa (0.5 kgf/cm2 , 7 psi), Relative pressure / -50 kPa (-0.5 kgf/cm2 , -7 psi) max.: Absolute pressure / 480 kPa (4.9 kgf/cm2 , 70 psi), Relative pressure / 380 kPa (3.9 kgf/cm2 , 55 psi)	Actual tire inflation pressure	If 50 kPa (0.5 kgf/cm2 , 7 psi) is displayed for absolute pressure or -50 kPa (-0.5 kgf/cm2 , -7 psi) is displayed for relative pressure, data has not been received.*

   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.
