DTC C1232: Acceleration Sensor Stuck Malfunction; DTC C1243: Acceleration Sensor Stuck Malfunction; DTC C1245: Acceleration Sensor Output Malfunction: Description
The skid control ECU receives signals from the yaw rate and acceleration sensor via the CAN communication system.
The yaw rate sensor has a built-in acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2).
If there is trouble in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, DTCs U0123 (malfunction in CAN communication with the yaw rate sensor) and U0124 (malfunction in CAN communication with the acceleration sensor) are set.
These DTCs are also output when calibration has not been completed.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1232 | At a vehicle speed of 10 km/h (6 mph) or more, acceleration sensor output value does not change for 30 seconds or more. |
|
| C1243 | While the vehicle speed changes from 30 km/h (19 mph) to 0 km/h (0 mph), the condition that the value of acceleration sensor does not change by 0.0294 G or more occurs 16 times or more. |
|
| C1245 | At a vehicle speed of 30 km/h (19 mph) or more, the difference between the longitudinal G calculated from the acceleration sensor value and that calculated from the vehicle speed sensor exceeds 0.35 G for 60 seconds or more. |
