Test Mode Procedure

HINT:

• When entering the TEST MODE, the tire pressure warning ECU sets all the test DTCs first. After completing the test mode for each inspection item, the DTCs that are determined normal by the tire pressure warning ECU will be erased.

  The DTCs for other inspection items may not be erased when only a certain signal is inspected.

• When the test mode returns back to the normal mode, all the test DTCs will be erased.

1. Make sure that the ignition switch is OFF.
2. Connect the intelligent tester (with CAN VIM) to the DLC3.
3. Turn the ignition switch ON.

HINT:

• When entering the signal check, the tire pressure warning ECU sets all the signal check DTCs first. After completing the signal check for each inspection item, the DTCs that are determined normal by the tire pressure warning ECU will be erased. The DTCs for other inspection items may not be erased when only a certain signal is inspected.
• When the signal check returns back to normal mode, all the signal check DTCs will be erased.

1. Make sure that the ignition switch is OFF.
2. Connect the intelligent tester (with CAN VIM ) to the DLC3.
3. Turn the ignition switch ON.
4. Select SIGNAL CHECK on the intelligent tester.
5. Drive the vehicle at 12 mph (20 km/h) or more for 10 seconds or more.

   HINT:

   The transmitter ID can be transmitted by rapidly reducing the tire pressure.

7. Result

   HINT:

   After the signal check is completed, check for a DTC and signal check DTC to confirm the system status.

   DTC CHECK CHART
   
   

   Condition	Procedure
   SIGNAL CHECK DTC is output	Repair faulty part and enter SIGNAL CHECK again
   SIGNAL CHECK DTCs are cleared	No problem

8. End of SIGNAL CHECK

   After completing test mode (SIGNAL CHECK), turn the ignition switch OFF and disconnect the tester.

   DTC of SIGNAL CHECK (TEST DIAGNOSIS) function: 

   If a malfunction code is displayed during the test mode DTC check, check the circuit listed for that code. For details of each code, refer to the "see page" of the "DTC No." in the chart.
