DTC Code DTC Name
C194F Operation of Static Test Mode is Incomplete (Test Mode DTC)
C1950 Front Stabilizer Target Angle Not Attained (Test Mode DTC)
C1951 Rear Stabilizer Target Angle Not Attained (Test Mode DTC)

DESCRIPTION

If the Active Test does not operate, test mode DTCs C194F and C1950 are output for the front, and C194F and C1951 are output for the rear. If system malfunction DTCs are already stored, test mode DTCs are not stored. During the Active Test, if the power switch is turned OFF or an actuator is malfunctioning, test mode DTCs are stored due to incompletion of operation. If this occurs, turn the power switch OFF (unless already turned OFF) and turn the power switch ON (READY). Then perform the Active Test to complete the operation normally, and the test mode DTC will be erased.
