| DTC Code | DTC Name |
|---|---|
| C1442 | Invalid Data Received from Deceleration Sensor |
| C1443 | Invalid Data Received from Yaw Rate Sensor |
DESCRIPTION
for Optitron Meter Type:
The airbag sensor assembly has a built-in yaw rate and acceleration sensor.
The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via the CAN communication system.
for TFT Meter Type:
The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor via the CAN communication system.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | Note |
|---|---|---|---|---|
| C1442 | Invalid Data Received from Acceleration Sensor | When voltage at terminal +BS is 9.5 to 17.4 V, sensor invalid information received from acceleration sensor is ON continuously for 10 seconds or more. |
|

CAUTION / NOTICE / HINT
Note
When replacing the yaw rate and acceleration sensor (airbag sensor assembly), perform zero point calibration and store system information (for optitron meter type).
When replacing the yaw rate and acceleration sensor, perform zero point calibration and store system information (for TFT meter type).
PROCEDURE
