Toyota Corolla Cross: Multi-axis Acceleration Sensor Module "A" Circuit Voltage Out of Range (C05201C,C135F00)
DESCRIPTION
The airbag ECU assembly has a built-in yaw rate and acceleration
sensor and detects the vehicle condition.
When the skid control ECU (brake actuator assembly) detects
an abnormal acceleration sensor (airbag ECU assembly) signal, or the control value
calculated using the acceleration sensor (airbag ECU assembly), yaw rate sensor
(airbag ECU assembly), steering sensor and speed sensor are compared and judged
to be abnormal, this DTC is stored.

Multi-axis Acceleration Sensor Module "A" Circuit Voltage
Out of Range
|
- When the vehicle is being driven and the stop light switch assembly
is OFF, the value (longitudinal) of the acceleration sensor (airbag
ECU assembly) is less than -4.0 m/s2 or more than 4.0 m/s2 for 20
seconds or more.
- When the vehicle is being driven, the difference in the acceleration
value (longitudinal) calculated using the speed sensors and the
acceleration value of the acceleration sensor (airbag ECU assembly)
is less than -3.5 m/s2 or more than 3.5 m/s2 for 4 seconds or more.
- When the vehicle is being driven in a straight line, the calculated
lateral acceleration value based on the speed sensors, steering
sensor angle and yaw rate sensor (airbag ECU assembly) differs from
the value (lateral) of the acceleration sensor (airbag ECU assembly).

When the vehicle is being driven in a straight line,
the calculated lateral acceleration value based on the speed sensors, steering
sensor angle and yaw rate sensor (airbag ECU assembly) differs from the
value (lateral) of the acceleration sensor (airbag ECU assembly).
