MULTI-MODE MANUAL TRANSAXLE SYSTEM, Diagnostic DTC:P0910

DTC Code DTC Name
P0910 Gate Select Actuator Circuit

DESCRIPTION

C256996C01

*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.

DTC No.

Gate Select Actuator Circuit

The TCM detects the following conditions:

(1-trip detection logic)

  1. Select motor is not energized.

  2. Select motor voltage is less than 0.5 V*1, or more than threshold*1 for 0.5 seconds.

  3. +BM voltage is 10 V or more.

The TCM detects the following conditions:

(1-trip detection logic)

  1. Select motor is energized.

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

  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.

  3. +BM voltage is 10 V or more.

  • Shift and select actuator assembly (select motor)

  • Wire harness or connector

  • TCM

DTC stored

  • *1: A short between the select motor circuit and the body ground is suspected.

  • *2: A short between the select motor circuit and the +B circuit is suspected.

  • *3: An open in the select motor circuit is suspected. If the motor current does not flow to the TCM terminals despite the TCM ordering the select motor to operate, the TCM stores this DTC.

  • *4: An open in the select motor circuit is suspected. If the difference is more than the threshold despite the TCM not ordering the select motor to operate, the TCM stores this DTC.

CAUTION / NOTICE / HINT

Note:

In select stroke sensor or shift and select actuator assembly replacement, perform the [Initialization and Learning] procedure and [Synchronization Position Calibration] procedure 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.
