Lexus RX (RX 350L, RX450h) 2016-2025 Repair Manual: Yaw Rate Sensor Circuit Intermittent (C00631F,C05201F)

Lexus RX (RX 350L, RX450h) 2016-2025 Repair Manual / Brake / Brake Control / Dynamic Control Systems / Vehicle Stability Control System / Yaw Rate Sensor Circuit Intermittent (C00631F,C05201F)

DESCRIPTION

for Optitron Meter Type:
  • The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.

    The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via CAN communication.

for TFT Meter Type:
  • The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor via CAN communication.

DTC No.

DTC Detection Condition

Trouble Area

C00631F

Yaw Rate Sensor Circuit Intermittent

When voltage at terminal +BS is 9.5 to 17.4 V, sensor invalid information received from yaw rate sensor is ON continuously for 10 seconds or more.
  • Yaw rate sensor (airbag sensor assembly) (for Optitron Meter Type)
  • Yaw rate sensor (yaw rate and acceleration sensor) (for TFT Meter Type)

C05201F

Multi-axis Acceleration Sensor Module "A" Circuit Intermittent

When voltage at terminal +BS is 9.5 to 17.4 V, sensor invalid information received from acceleration sensor is ON continuously for 10 seconds or more.
  • Acceleration sensor (airbag sensor assembly) (for Optitron Meter Type)
  • Acceleration sensor (yaw rate and acceleration sensor) (for TFT Meter Type)

CAUTION / NOTICE / HINT

NOTICE:

If the yaw rate and acceleration sensor (airbag sensor assembly) was replaced or reinstalled, perform "Calibration". (for Optitron Meter Type)

If the yaw rate and acceleration sensor was replaced or reinstalled, perform "Calibration". (for TFT Meter Type)
