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

      HINT: 

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

C → See step   8 

A: Go to next step 

1. Turn the power switch off.
2. Install only the left front tire and move the remaining tires 10 m (32.8 ft.) or more away from the vehicle.

5. Turn the Techstream on.
6. Enter the following menus: Chassis / Tire Pressure Monitor / Utility / Signal Check.
7. Step A:

   Enter test mode. Refer to TEST MODE PROCEDURE [08/2013 - ] .

8. Step B:

   Turn the power switch off and then on (IG), and then perform a test mode inspection to check whether any DTCs C2181/81 to C2184/84 (w/ Full Size Spare Tire: C2185/85) are cleared.

9. Step C:

   Repeat steps A and B after returning to normal mode from test mode.

   NOTE:

   Be sure to perform steps A through C within 60 seconds.

   HINT: 

   In order to determine whether the system is responding to the tire pressure warning valve and transmitter periodic transmission (sent at approximately 1.5 second intervals) or the front or rear tire pressure monitor initiator transmission, perform the check twice within 60 seconds.

10. Perform the same inspection for all of the remaining tires.

    Malfunctioning Tire Identification

    The malfunctioning tire is the one which none of the DTCs C2181/81 to C2184/84 (w/ Full Size Spare Tire: C2185/85) were cleared. The tire pressure warning valve and transmitter for that tire can be determined to be malfunctioning.
