Circuit Description
If a malfunction in the speed sensor signal circuit or the yaw rate sensor circuit occurs, the 4WD control module will output this DTC.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC C1298 Linear Solenoid Circuit
Conditions for Running the DTC
This DTC shall run when the ignition is On.
Conditions for Setting the DTC
For 1 second or more, with the current of 0.8 A or more, an open or short in the linear solenoid circuit occurs.
Action Taken When the DTC Sets
The 4WD control module will prohibit operations by the fail safe function.
Conditions for Clearing the DTC
The DTC will clear when conditions for setting the DTC have been repaired.
