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 set 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 set before this DTC is set.

DTC No. DTC Detection Condition Trouble Area
P0909

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.

  • Select stroke sensor

  • Shift and select actuator assembly (select motor)

  • TCM

  • Transaxle assembly

CAUTION / NOTICE / HINT

Note

In select 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 shift heads and shift fork shafts for dirt, wear, and defects and replacing the defective parts, replace the TCM.
