Toyota Camry (XV70): Multi-axis Acceleration Sensor Module "A" Signal Stuck In Range (C05202A)
DESCRIPTION
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) memorizes the range of the acceleration sensor (airbag sensor assembly) and the range of vehicle speed calculated using each speed sensor.
If the range of the acceleration sensor (airbag sensor 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.

CAUTION / NOTICE / HINT
NOTICE:
After replacing or reinstalling the yaw rate and acceleration sensor (airbag sensor assembly), perform acceleration sensor zero point calibration and system information memorization after performing "Reset Memory".

DESCRIPTION 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
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 sensor assembly

On-vehicle Inspection
ON-VEHICLE INSPECTION PROCEDURE
1. INSPECT BRAKE BOOSTER ASSEMBLY (a) Airtightness check
(1) Start the engine and stop it after 1 or 2 minutes. Slowly depress the brake pedal several times.
If the brake pedal can be depressed nearly to the floor the first time, but on the 2nd and 3rd time
Installation
INSTALLATION PROCEDURE 1. TEMPORARILY INSTALL FUEL (ENGINE ROOM SIDE) PUMP ASSEMBLY
(a) Turn the crankshaft pulley until the flat of the camshaft faces the fuel pump lifter assembly.
HINT: This prevents the camshaft nose from pushing up the fuel pump lifter assembly when installing the fuel
