MULTI-MODE MANUAL TRANSAXLE SYSTEM, Diagnostic DTC:P0919

DTC Code DTC Name
P0919 Gear Shift Position Control Error

DESCRIPTION

In the multi-mode manual transaxle system, the transaxle gear is shifted up and down by the TCM using a shift and select actuator. The shift and select actuator assembly consists of two motors (shift motor and select motor), stroke sensors (shift stroke sensor and select stroke sensor) and gears to move the shift and select lever shaft. The shift motor moves the shift and select lever shaft in the shift direction according to the signal from the TCM.

This DTC is set in accordance with the stroke speed of the shift and select actuator or the difference between the target shift position and the actual shift position. Therefore, if malfunctions occur in the shift stroke sensor or the shift motor circuit, the DTCs relating to the sensor or motor circuit open/short (DTC P0915, P0916, P0917 and/or P0920) are set before this DTC is set.

DTC No. DTC Detection Condition Trouble Area
P0919

The TCM detects the following conditions simultaneously for 2.0 seconds:

(1-trip detection logic)


  1. Shift motor current is 20A or more, -20A or less.

  2. Difference between target shift position and actual shift position is 0.3 mm (0.0118 in.) or more.

  3. Shift and select actuator movement is 122 mm/sec (4.8 in./sec) or less.

  • Shift stroke sensor

  • Shift and select actuator assembly (shift motor)

  • TCM

  • Transaxle assembly

CAUTION / NOTICE / HINT

Note

In shift stroke sensor or shift and select actuator assembly replacement, perform the [Initialization and Learning] procedure (See page ) and [Synchronization Position Calibration] procedure Click here after installing the sensor or actuator assembly. If the sensor or actuator is installed without performing [Initialization and Learning] and [Synchronization Position Calibration], it may cause driving performance degradation or system component breakage.

Tech Tips

If the symptom still occurs even after checking the following parts for dirt, wear, and defects and replacing the defective parts, replace the TCM.


  • Synchronizer rings

  • Shift forks

  • Hub sleeves

PROCEDURE


  1. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (TARGET GEAR POSITION CONTROL)


    1. Remove the shift and select actuator assembly Click here.

    2. Connect the B58 shift and select actuator assembly connector.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the tester on.

    6. Enter the following menus: Powertrain / Multi-Mode M/T / Active Test / Target Gear Position Control.

      OK
      Shift and select actuator moves smoothly in accordance with the tester operation.
