Lexus ES: Multi-axis Acceleration Sensor Module "A" Signal Stuck In Range (C05202A)
DESCRIPTION
The airbag ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.
The skid control ECU (brake actuator assembly) memorizes the range of the acceleration sensor (airbag ECU assembly) and the range of vehicle speed calculated using each speed sensor.
If the range of the acceleration sensor (airbag ECU assembly) and the range of vehicle speed calculated using each speed sensor are judged to be abnormal when compared to their past memorized range, this DTC is stored.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| C05202A | Multi-axis Acceleration Sensor Module "A" Signal Stuck In Range | The memorized range (longitudinal) of the acceleration sensor (airbag ECU assembly) is judged to be abnormal when compared to its past memorized range. | Acceleration sensor (airbag ECU assembly) |
CAUTION / NOTICE / HINT
NOTICE:
After replacing or reinstalling the yaw rate and acceleration sensor (airbag ECU assembly), perform acceleration sensor zero point calibration and store system information memorization after performing "Reset Memory".

Steering Angle Sensor Module Circuit Voltage Out of Range (C05261C)
DESCRIPTION The skid control ECU (brake actuator assembly) compares the calculated steering angle value based on the yaw rate sensor value with the actual steering angle value of the steering sensor.
Steering Angle Sensor Module Signal Stuck In Range (C05262A)
DESCRIPTION The skid control ECU (brake actuator assembly) determines the steering angle value based on data obtained from the steering sensor, yaw rate and acceleration sensor (airbag ECU assembly).
Brake Pressure Sensor "A" Circuit Voltage Out of Range (C05401C,C054028,C054049)
DESCRIPTION The master cylinder pressure sensor is connected to the skid control ECU in the brake actuator assembly. DTC No. Detection Item DTC Detection Condition Trouble Area C05401C

Transmission Fluid Temperature Sensor "A" Circuit Range/Performance (P071000)
DESCRIPTION The ATF temperature sensor converts the automatic transaxle fluid (ATF) temperature into a resistance value for use by the ECM. The ECM applies a voltage to the temperature sensor through terminal THO1 of the ECM. The sensor resistance changes with the ATF temperature. As the temperature
Front Left Sensor Malfunction (C1AE1)
DESCRIPTION The front corner ultrasonic sensor LH is installed to the front bumper. The clearance warning ECU assembly detects obstacles based on signals received from the front corner ultrasonic sensor LH. If the front corner ultrasonic sensor LH has an open circuit or other malfunction, it will no
