DESCRIPTION

WIRING DIAGRAM

INSPECTION PROCEDURE

NOTICE:

1. When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.
   
2. It is necessary to perform initialization (Click here) after registration (Click here) of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.
   

1. Disconnect the L85 tire pressure warning ECU and receiver connector.
   

2. Disconnect the A77 tire pressure warning antenna connector.
   

3. Measure the resistance according to the value(s) in the table below.
   

   HINT:

   Because the coaxial cable that is used for the tire pressure warning antenna consists of a center conductor and an outer shielding layer (-), this measurement should be performed to ensure that there is no malfunction in the coaxial cable.

   
   

   Standard Resistance:

   
   

   Tester Connection	Condition	Specified Condition
   L85-1 (TPMS) - A77-1 (TPMS)	Always	Below 1 Ω
   L85-1 (shielded wire) - A77-1 (shielded wire)	Always	Below 1 Ω
   L85-1 (TPMS) - A77-1 (shielded wire)	Always	10 kΩ or higher
   L85-1 (shielded wire) - A77-1 (TPMS)	Always	10 kΩ or higher

1. Set the tire pressure to the specified value (Click here).
   

2. Turn the engine switch off.
   

3. Connect the L85 tire pressure warning ECU and receiver connector.
   

4. Connect the A77 tire pressure warning antenna connector.
   

   NOTICE:

   Be sure to disconnect the connector on the tire pressure warning antenna.

5. Connect the GTS to the DLC3.
   

6. Turn the engine switch on (IG).
   

7. Turn the GTS on.
   

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

9. Check the values by referring to the table below.

   HINT:

   1. *: It may take a few minutes until the values are displayed.
      
   2. The wheel position cannot be determined from ID1 through ID5 on the Data List.
      

10. Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm², 5.8 psi) within 30 seconds.
    

    1. Check that each tire pressure value displayed on the GTS has changed.
