TIRE PRESSURE WARNING SYSTEM, Diagnostic DTC:C2197/97

DTC Code DTC Name
C2197/97 Tire Position Non-decision (Test Mode DTC)

DESCRIPTION

Tire position identification operates using the following principles.

For front position identification (rear position identification is performed in the same way):


  1. The front tire pressure monitor initiator sends a position identification signal to all of the tire pressure warning valve and transmitters.

  2. The tire pressure warning valve and transmitters respond to the received position identification signal by sending a signal to the tire pressure warning ECU and receiver indicating the strength of the received signal.

    Tech Tips

    The strength of the signals is different because the distance between the front tire pressure monitor initiator and each tire is different.

  3. The tire pressure warning ECU and receiver receives the signal strength information signals from each of the tire pressure warning valve and transmitters and associates them with their correct position based on the received information.

  4. CHECK TIRE PRESSURE WARNING VALVE AND TRANSMITTER (DETERMINE LOCATION OF MALFUNCTION)


    1. Turn the engine switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the engine switch on (IG).

    4. Turn the GTS on.

    5. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

    6. Record all of the tire pressure warning valve and transmitter IDs from the Data List screen.

    7. Perform the following procedure to determine the location of the malfunction.


      1. For front tires:

        A01FJ51

        1. Remove the right front tire and place it near the left front tire.

        2. Remove the right rear tire and place it near the left rear tire.

        3. w/ Full Size Spare Tire:

          Remove the spare tire and place it near the left rear tire.

        4. Perform tire pressure warning valve and transmitter ID registration Click here

      2. For rear tires:

        A01FHRGE01

        1. Install the front right tire.

        2. Perform tire pressure warning valve and transmitter ID registration Click here

        Tech Tips

        If ID registration does not finish in approximately 2 seconds, rotate the tires 90 to 270 degrees and perform the inspection again.

        Result
        Result Proceed to
        ID verification finishes approximately 90 seconds after ID registration is finished A
        When checking the front tires, ID verification finishes approximately 2 seconds after ID registration is finished B
        When checking the rear tires, ID verification finishes approximately 2 seconds after ID registration is finished C

        Tech Tips

        After finishing ID registration, the tire pressure warning light blinks for 1 minute and then illuminates continuously. When ID verification is finished, the tire pressure warning light turns off.

  5. DETERMINE MALFUNCTIONING TIRE PRESSURE WARNING VALVE AND TRANSMITTER


    1. Turn the engine switch off.

    2. A01FFA6E01
      Text in Illustration
      *a 10 m (32.8 ft.) or more

      Install only the left front tire and move the remaining tires 10 m (32.8 ft.) or more away from the vehicle.

    3. Connect the GTS to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the GTS on.
