P08BA14 Pressure Control Solenoid "L" Circuit Short to Ground or Open While the vehicle is being driven so that gear changes occur, a short to ground or open is detected in the solenoid (SL6) valve circuit for 1 second (1-trip detection logic).

  • Solenoid (SL6) valve

  • Transmission wire

  • Harness and connector

  • ECM

SAE Code:

P08C1

MONITOR DESCRIPTION

This DTC indicates an open or short to ground in the solenoid (SL6) valve circuit. The ECM commands gear shifts by turning the solenoid valves on or off. When there is an open or short in any solenoid valve circuit, the ECM detects the problem, illuminates the MIL and stores a DTC.

The ECM performs the fail-safe function and turns the other normal solenoid valves on or off. In the case of an open or short circuit, the ECM stops sending current to the open or shorted solenoid.

CONFIRMATION DRIVING PATTERN

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

Tech Tips

After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the engine switch off and wait for 2 minutes or more.

  5. Turn the engine switch on (IG) and turn the GTS on.

  6. Start the engine.

  7. Perform the D Position Shift Test inspection in Road Test.

  8. Stop the vehicle.

  9. Enter the following menus: Powertrain / Transmission / Utility / All Readiness.

  10. Input the DTC: P08BA14.

  11. Check the DTC judgment result.

    GTS Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

PROCEDURE


  1. CHECK HARNESS AND TRANSMISSION WIRE (TRANSMISSION WIRE (SOLENOID (SL6) VALVE) - ECM)


    1. Disconnect the D110 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D110-32 (SL6+) - D110-33 (SL6-) 20°C (68°F) 5.0 to 5.6 Ω
      D110-32 (SL6+) or D110-33 (SL6-) - Body ground and other terminals Always 10 kΩ or higher

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      Solenoid (SL6) valve connector terminal 1 - 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.
