DTC P177C-62: Gear Lever Position / Transmission Position Signal Compare Failure [11/2021 - ]: Description
WARNING: This page is about a different car, the 2025 Lexus NX 250, 2024 Lexus NX 250, 2023 Lexus NX 250, and 2022 Lexus NX 250. However, it is still accessible from the selected car via links, so may be relevant.
The shift control actuator assembly consists of a shift actuator ECU, motor, motor rotation angle sensor and output shaft rotation angle sensor. The shift control actuator assembly operates the motor in accordance with the operation signal from the shift control ECU to change the shift state between P, R, N and D.
The motor rotation sensor detects the motor angle and optimizes the motor speed and current.
The output shaft rotation angle sensor determines the shift state based on the sensor angle and transmits the state to the shift control ECU.
If the shift control ECU determines that the shift control actuator assembly is malfunctioning, the ECM stores a DTC.
