Diagnostic Work SheetINFOID:0000000009464659
DESCRIPTION
In general, each customer feels differently about an inci dent. 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.
