DTC C1242: G and Yaw Rate Sensor (Longitudinal G Output Data Error): Notes

CAUTION:

If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be set. Prior to this diagnosis, diagnose the CAN bus lines.
Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
Do not drop the G and yaw rate sensor or subject it to a shock.
When G and yaw rate sensor is replaced, calibrate G and yaw rate sensor (refer to ON-VEHICLE SERVICE ) and initialize the lateral/longitudinal acceleration correction amount stored in AWC-ECU. (Refer to ITEM NO. 2: LATERAL ACCELERATION CORRECTION AMOUNT INITIALIZATION , and NO. 3: LONGITUDINAL ACCELERATION CORRECTION AMOUNT INITIALIZATION .)
