    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Check that the steering column contracts (extends). Enter the following menus: Chassis / Tilt&Telescopic / Active Teste.
      TILT&TELESCOPIC

      Tester Display Test Part Control Range Diagnostic Note
      Telesco Telesco operation Operation LONG / SHORT -

      OK

      Steering column contracts (extends).

    OK → See step   3 

    NG: Go to next step 

  2. INSPECT TELESCOPIC MOTOR 
    1. Disconnect connector A from the multiplex tilt & telescopic ECU.

    2. Connect the positive battery terminal to terminal TEM+ and the negative battery terminal to terminal TEM- of the telescopic motor connector. Then confirm that the steering column contracts.

      OK

      Steering column contracts.

    3. Connect the negative battery terminal to terminal TEM+ and the positive battery terminal to terminal TEM- of the telescopic motor connector. Then confirm that the steering column extends.

      OK

      Steering column extends.

    NG → REPLACE STEERING COLUMN ASSEMBLY 

    OK → REPLACE MULTIPLEX TILT & TELESCOPIC ECU 

  3. INSPECT MULTIPLEX TILT & TELESCOPIC ECU (VCE TERMINAL VOLTAGE) 
    1. Measure the voltage according to the value(s) in the table below.
      GTY276171Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

      Standard voltage

      Tester connection Condition Specified value
      VCE - E1 Engine switch on (IG) 8 to 16 V

    NG → See step   5 

    OK: Go to next step 

  4. INSPECT TELESCOPIC POSITION SENSOR 
    1. Measure the voltage according to the value(s) in the table below.
      GTY286643Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

      Standard voltage

      Tester connection Condition Specified value
      TES - E1 Telescopic steering contracts or extends 8 to 16 V (Pulse HI)
      Below 1 V (Pulse LOW)

    NG → REPLACE STEERING COLUMN ASSEMBLY 

    OK → REPLACE MULTIPLEX TILT & TELESCOPIC ECU 

  5. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - BODY GROUND (VCE CIRCUIT)) 
    1. Disconnect connector A from the multiplex tilt & telescopic ECU.

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

      Standard resistance

      Tester connection Condition Specified value
      VCE - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  6. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - BODY GROUND (GND CIRCUIT)) 
    1. Disconnect the J28 connector from the multiplex tilt & telescopic ECU.

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

      Standard resistance

      Tester connection
      (Terminal No.)      		 Condition Specified value
      GND (J28-11) - Body ground Always Below 1 Ω

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → REPLACE MULTIPLEX TILT & TELESCOPIC ECU
