METER / GAUGE SYSTEM Satellite Switch Circuit

DESCRIPTION

The meter CPU receives satellite switch signals from the satellite switch in this circuit. The meter CPU sends satellite switch signals to the main body ECU RH (cowl side junction block RH), clearance warning ECU*1, and seat belt control ECU*2 using the BEAN lines. Each system ECU is controlled based on these signals.

INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT SATELLITE SWITCH


    1. A0160U0E06

      Disconnect the J16 connector.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      2 (LSFT) - 5 (E) Satellite switch LH is pressed Below 1 Ω
      2 (LSFT) - 5 (E) Satellite switch LH is not pressed 10 kΩ or higher
      3 (SET) - 5 (E) Satellite switch ON/OFF is pressed Below 1 Ω
      3 (SET) - 5 (E) Satellite switch ON/OFF is not pressed 10 kΩ or higher
      4 (RSEL) - 5 (E) Satellite switch RH is pressed Below 1 Ω
      4 (RSEL) - 5 (E) Satellite switch RH is not pressed 10 kΩ or higher

  2. CHECK HARNESS AND CONNECTOR (COMBINATION METER - SATELLITE SWITCH)


    1. Disconnect the J35 connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      J35-5 (RSEL) - J16-4 (RSEL) Always Below 1 Ω
      J35-6 (LSEL) - J16-2 (LSFT) Always Below 1 Ω
      J35-7 (SET) - J16-3 (SET) Always Below 1 Ω
      J16-2 (LSFT) - Body ground Always 10 kΩ or higher
      J16-3 (SET) - Body ground Always 10 kΩ or higher
      J16-4 (RSEL) - Body ground Always 10 kΩ or higher
