P0910 Gate Select Actuator Circuit

DESCRIPTION

B0042NCC02
*a Shift and Select Actuator Operation
*b Shift Direction
*c Select Direction

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 Gate Select Actuator Circuit

The TCM detects the following conditions:

(1-trip detection logic)


  1. Select motor is not energized.

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

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.
