Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM (w/o Electric Parking Brake System): C1336; Zero Point Calibration of Acceleration Sensor Undone; 2018 - 2020 MY Camry [06/2017 - 10/2020]

DTC

C1336

Zero Point Calibration of Acceleration Sensor Undone

DESCRIPTION

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

The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2). If a communication error with the yaw rate and acceleration sensor (airbag sensor assembly) is detected, DTCs U0123 (Lost Communication with Yaw Rate Sensor Module) and U0151 (Lost Communication with Airbag ECU) are stored.

The DTCs are also stored when the calibration has not been completed.

DTC No.

Zero Point Calibration of Acceleration Sensor Undone

Zero point calibration of acceleration sensor undone.

  • Acceleration sensor (airbag sensor assembly) installation
  • Acceleration sensor (airbag sensor assembly)
  • Skid control ECU (brake actuator assembly)

CAUTION / NOTICE / HINT

NOTICE:

  • When replacing the skid control ECU (brake actuator assembly), perform system variant learning and acceleration sensor zero point calibration.
