Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM (w/o Electric Parking Brake System): C1420; Acceleration Sensor Malfunction; 2018 - 2020 MY Camry [06/2017 - 10/2020]

DTC

C1420

Acceleration Sensor Malfunction

DESCRIPTION

This DTC is stored when the skid control ECU (brake actuator assembly) detects an abnormality in the difference between the acceleration sensor value and the control value estimated based on the yaw rate sensor, steering angle sensor and speed sensor signals.

The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.

DTC No.

Acceleration Sensor Malfunction

The difference between the acceleration sensor value and the control value estimated inside the skid control ECU (brake actuator assembly) is abnormal.

  • Acceleration sensor (airbag sensor assembly) installation
  • Acceleration sensor (airbag sensor assembly)

CAUTION / NOTICE / HINT

NOTICE:

After replacing or reinstalling the yaw rate and acceleration sensor (airbag sensor assembly), perform system variant learning and acceleration sensor zero point calibration.

OK:

The yaw rate and acceleration sensor (airbag sensor assembly) is tightened to the specified torque.

The yaw rate and acceleration sensor (airbag sensor assembly) is not installed in a tilted position.

OK
