MULTI-MODE MANUAL TRANSAXLE SYSTEM, Diagnostic DTC:P0909

DTC Code DTC Name
P0909 Gate Select 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 which move the shift and select lever shaft. The select motor moves the shift and select lever shaft in the select direction in accordance with the signal from the TCM.

This DTC is stored in accordance with the stroke speed of the shift and select actuator or the difference between the target select position and the actual select position. Therefore, if malfunctions occur in the select stroke sensor or the select motor circuit, the DTCs relating to the sensor or motor circuit open/short (DTC P0905, P0906, P0907 and/or P0910) are stored before this DTC is stored.

DTC No.

Gate Select Control Error

The TCM detects the following conditions simultaneously for 2.0 seconds:

(1-trip detection logic)

  1. Select motor current is 16 A or more, or -16 A or less.

  2. Difference between target select position and actual select 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.

If the sensor or actuator is installed without the initialization and learning procedures, it may cause driving performance degradation or system component breakage.

Tip:

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

PROCEDURE

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

    1. Remove the shift and select actuator assembly.

      Click here

    2. Connect the shift and select actuator assembly connector.

    3. Connect the GTS to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the GTS on.

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