Abnormal Output in Deceleration Sensor

DESCRIPTION

The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2).

The skid control ECU (brake booster with master cylinder assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via the CAN communication system.

HINT:

When a malfunction occurs in the communication line to the yaw rate and acceleration sensor (airbag sensor assembly), U0124 (Lost Communication With Lateral Acceleration Sensor Module) is output.

If a DTC related to the CAN communication line is output, first troubleshoot the CAN communication line.

A DTC may be stored if either of the following is detected:

  • Incorrect installation of acceleration sensor (airbag sensor assembly).
  • Abnormal acceleration sensor (airbag sensor assembly) signal.

DTC No.

CAUTION / NOTICE / HINT

NOTICE:

After replacing or reinstalling the yaw rate and acceleration sensor (airbag sensor assembly), perform yaw rate and acceleration sensor zero point calibration after clearing previously calibrated data.

PROCEDURE

1.

CHECK AIRBAG SENSOR ASSEMBLY INSTALLATION

(a) Check that the yaw rate and acceleration sensor (airbag sensor assembly) has been installed properly.

Click here 2018 - 2024 MY Camry HV [07/2017 -        ]; SUPPLEMENTAL RESTRAINT SYSTEMS: CENTER AIRBAG SENSOR ASSEMBLY: INSTALLATION

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 tilted.

OK

REPLACE AIRBAG SENSOR ASSEMBLY
