DESCRIPTION

The shift and select actuator is operated by the TCM and changes the transaxle gear by moving the shift and select lever shaft. An electric motor (select motor) moves the shift and select lever shaft in the select direction, and the select stroke sensor, which is mounted on the shift and select actuator assembly, detects the select position. The TCM monitors the electrical current and select motor output terminal voltage, and detects malfunctions in the select motor circuit.

P0910

The TCM detects the following conditions:

(1-trip detection logic)


  1. Select motor is not energized.

  2. Voltages of select motor terminal (MSL+ or MSL-) is less than threshold*1, or more than threshold*2 for 0.5 seconds.

  • Shift and select actuator assembly (select motor)

  • Wire harness or connector

  • TCM

The TCM detects the following conditions:

(1-trip detection logic)


  1. Select motor is energized.

  2. Target select motor current is more than 5 A.

  3. Actual select motor current is less than 1 A*3.

The TCM detects the following conditions:

(1-trip detection logic)


  1. Select motor is not energized.

  2. Difference between maximum and minimum voltages of select motor terminal (MSL+ or MSL-) is more than threshold*4 for 0.5 seconds.

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.
