DESCRIPTION

In general, each customer feels differently about an incident. It is important to fully understand the symptoms
or conditions for a customer complaint.
There are many operating conditions that lead to the malfunction. A good grasp of such conditions can make
troubleshooting faster and more accurate.
Some conditions may cause the lane departure warning lamp to stay ON.
Utilize a work sheet sample to organize all of the information for troubleshooting.
