DTC C1420 Acceleration Sensor Malfunction: Description
The skid control ECU receives signals from the yaw rate and deceleration sensor via the CAN communication system.
The yaw rate sensor has a built-in deceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2).
If there is trouble in the bus lines between the yaw rate and deceleration 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 stored.
These DTCs are also output when calibration has not been completed.
