Inspection Procedure

WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • When replacing the tire pressure warning ECU and receiver, read the IDs stored in the old ECU using the intelligent tester and note them down before removal.
  • It is necessary to perform initialization (see INITIALIZATION ) after registration (see REGISTRATION ) of the transmitter IDs into the tire pressure warning ECU and receiver after the ECU and/or valve and transmitter has been replaced.
  1. CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES) 
    1. Turn the ignition switch OFF.
    2. Connect the intelligent tester to the DLC3.
    3. Turn the ignition switch ON and the tester ON.
    4. Following the display on the intelligent tester, select the "DATA LIST".
    5. Check the values by referring to the table below.

    Tester Display Measurement Item/Range Normal Condition Diagnostic Note
    REGIT ID1 CODE Registered ID1 code/ min.: 0 max.: FFFFFFF* The ID No. registered in the transmitter ID1 is displayed *: Displayed only when the ID No. is not registered.
    REGIT ID2 CODE Registered ID2 code/ min.: 0 max.: FFFFFFF* The ID No. registered in the transmitter ID2 is displayed *: Displayed only when the ID No. is not registered.
    REGIT ID3 CODE Registered ID3 code/ min.: 0 max.: FFFFFFF* The ID No. registered in the transmitter ID3 is displayed *: Displayed only when the ID No. is not registered.
    REGIT ID4 CODE Registered ID4 code/ min.: 0 max.: FFFFFFF* The ID No. registered in the transmitter ID4 is displayed *: Displayed only when the ID No. is not registered.
    REGIT ID5 CODE Registered ID5 code/ min.: 0 max.: FFFFFFF* The ID No. registered in the transmitter ID5 is displayed *: Displayed only when the ID No. is not registered.

    OK: The registered transmitter ID codes are displayed on the intelligent tester. 

    OK: GO TO step   4

    NG: GO TO next step. 

  2. PERFORM REGISTRATION 
    1. Register the transmitter IDs for all the wheels (see REGISTRATION ).
  3. PERFORM INITIALIZATION 
    1. Perform initialization (see INITIALIZATION ).
  4. READ VALUE OF DATA LIST (TIRE INFLATION PRESSURE) 
    1. Turn the ignition switch OFF.
    2. Connect the intelligent tester to the DLC3.
    3. Turn the ignition switch ON and the tester ON.
    4. Following the display on the intelligent tester, select the "DATA LIST".
    5. Check the values by referring to the table below.
