Vehicle Stability Control System (w/ VDIM)

DTC C1244/44 Open or Short in Acceleration Sensor Circuit

DESCRIPTION

DTC Detection Condition:

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, the DTCs U0123/62 (malfunction in CAN communication with the yaw rate sensor) and U0124/95 (malfunction in CAN communication with the acceleration sensor) are output. These DTCs are also output when the calibration has not been completed.

DTCs C0371/71 and C1279/79 can be deleted when the yaw rate and acceleration sensor sends a yaw rate and/or acceleration signal or the Test Mode ends. DTCs C0371/71 and C1279/79 are output only in the Test Mode.

INSPECTION PROCEDURE

NOTE: When replacing the yaw rate and acceleration sensor, perform zero point calibration. Vehicle Stability Control System (W/ VDIM)

HINT: When U0123/62, U0124/95 or U0126/63 is output together with C1232/32, C1234/34, C1243/43, C1244/ 44, C1245/45, or C1381/97, inspect and repair the trouble areas indicated by U0123/62, U0124/95 or U0126/63 first.
