DIAGNOSTIC PROCEDURE

STEP INSPECTION ACTION

  • Are all four wheels equipped with a wheel unit?
 Yes Go to the Step 3.
No
2 INSPECT FOR DTCs 
  • Drive the vehicle at a speed of 25 km/h {15.5 mph} or more  for 10 min or more. 
  • Is the same DTC present?
 Yes Go to the next step.
No With advanced keyless system: go to the Step 4. With keyless entry system, and without advanced keyless system and keyless entry system: go to the Step 5.
3 IDENTIFY MALFUNCTIONING WHEEL UNIT 
4 INSPECT FOR KEYLESS CM MALFUNCTION 
  • Turn the ignition switch off.
  • Using the WDS or equivalent, perform the DTC inspection for the keyless CM.
  • Is any DTCs present?
 Yes Go to the applicable DTC inspection. (See DTC TABLE [ADVANCED KEYLESS SYSTEM] .)
No Go to the next step.
5 VERIFY TROUBLESHOOTING COMPLETED 
  • Clear the DTC from the memory. (See CLEARING DTCS PROCEDURE  .)
  • Drive the vehicle at a speed of 25 km/h {15.5 mph} or more  for 10 min or more. 
  • Is the same DTC present?

No Go to the next step.
6 VERIFY AFTER REPAIR PROCEDURE 
  • Are there any other DTCs present?
 Yes Go to the applicable DTC inspection. (See DTC TABLE  .)
No DTC troubleshooting completed.
NOTE:
  • If the installed wheel unit ID number is known, verification of whether the instrument cluster is receiving data from the wheel unit can be easily confirmed using the following procedure:
    1. Drive the vehicle at 25 km/h {15.5 mph} or more  , and send data from the wheel unit.
    2. Select [ID_LAST] from the PID items, and monitor the data.
    3. Verification that the instrument cluster is receiving data is possible if the monitored ID number matches the installed wheel unit ID number.
  • If the wheel unit has been newly replaced, the TPMS warning light may flashes before the ID registration is complete, and DTC U2616, U2617, U2618 and U2619 may be stored in the memory. In this case, re-implement the wheel unit ID registration, and after confirming that the TPMS warning light is no longer flashing, erase the DTC. If the TPMS warning light does not go out, a malfunction on any one of the wheel units may have occurred and the ID registration will not have been correctly performed. Repeat the diagnostic procedure from Step  1 and perform the inspection
