HYBRID CONTROL SYSTEM Solenoid Valve Circuit

DESCRIPTION

The cause of this malfunction may be the motor resolver.

Check the installation condition of the solenoids installed to each solenoid valve and transmission valve body.

Related Parts Check
Area Inspection Step
Solenoid valve Check internal resistance of each solenoid valve 1, 2, 3
Transmission valve body assembly Check solenoid installation conditions 4

CAUTION / NOTICE / HINT

This procedure is referenced from the procedures for each DTC.

If the following inspection results are normal, perform the next procedure for the referenced DTC.

PROCEDURE


  1. INSPECT SOLENOID (SL1), (SL2), (SL3) AND (SL4) VALVE


    1. B000T21C01
      *a

      Component without harness connected

      (Solenoid (SL1), (SL2), (SL3) and (SL4) Valves)

      Remove the solenoid (SL1), (SL2), (SL3) and (SL4) valves.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      Terminal 1 of the solenoid (SL1) valve - terminal 2 20°C (68°F) 5.0 to 5.6 Ω
      Terminal 1 of the solenoid (SL2) valve - terminal 2 20°C (68°F) 5.0 to 5.6 Ω
      Terminal 1 of the solenoid (SL3) valve - terminal 2 20°C (68°F) 5.0 to 5.6 Ω
      Terminal 1 of the solenoid (SL4) valve - terminal 2 20°C (68°F) 5.0 to 5.6 Ω

    3. Connect a positive (+) lead from the battery with a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector. Check that the valve moves and makes an operating sound.

      OK
      Valve moves and makes an operating sound.

    4. Install the solenoid (SL1), (SL2), (SL3) and (SL4) valves.

  2. INSPECT SOLENOID (SC1) AND (SC2) VALVE


    1. B000OFDC01
      *1 Solenoid (SC1) and (SC2) Valves

      Remove the solenoid (SC1) and (SC2) valves.

      Click here

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      Terminal of solenoid (SC1) valve connector - Solenoid (SC1) valve body 20°C (68°F) 11 to 15 Ω
      Terminal of solenoid (SC2) valve connector - Solenoid (SC2) valve body 20°C (68°F) 11 to 15 Ω

    3. Connect a positive (+) lead from the battery to the terminal of the solenoid valve connector, and a negative (-) lead to the solenoid body. Check that the valve moves and makes an operating sound.

      OK
      Valve moves and makes an operating sound.

    4. Install the solenoid (SC1) and (SC2) valves.

    OK

  3. INSPECT SOLENOID (SLT) VALVE


    1. B000OPEC34
      *a

      Component without harness connected

      (Solenoid (SLT) Valve)

      Remove the solenoid (SLT) valve.

      Click here

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      Terminal 1 of the solenoid (SLT) valve - terminal 2 20°C (68°F) 5.0 to 5.6 Ω

    3. Connect a positive (+) lead from the battery with a 21 W bulb to terminal 1 and a negative (-) lead to terminal 2 of the solenoid valve connector. Check that the valve moves and makes an operating sound.

      OK
      Valve moves and makes an operating sound.

    4. Install the solenoid (SLT) valve.
