Driver Assistance Systems Disable History Conditions
When attempting to diagnose the advanced driver assistance systems, it is important to discuss with the customer the conditions under which the apparent malfunction occurred. This is critical to help identify those scenarios where the inhibit or disengage is the result of a driver action or normal system response. It is also critical to identify when the apparent malfunction occurred when attempting to replicate the condition. The parameters in the scan tool Disable History Data lists can be used to help isolate what is causing an inhibit or disengage condition. When diagnosing a disable concern, especially in the case of an intermittent condition, these parameters are useful in helping determine the cause. Recurring causes will have a larger number in the Malfunction Counter parameter and will likely have a wide variance between the Odometer at First Malfunction and Odometer at Last Malfunction value, indicating the condition has occurred over a period of time driving the vehicle.
NOTE:
If any DTCs are set, diagnose those first.
NOTE:
Due to software and hardware variations, not all information may be applicable.
NOTE:
When directed in Corrective Action to check scan tool information, refer to Control Module References.
