Example: 
 
Warning: Retrieving and using DTCs for troubleshooting vehicle operation is only 
one part of an overall diagnostic strategy. Never replace a part based only on the DTC 
definition. Each DTC has a set of testing procedures, instructions and flow charts that 
must be followed to confirm the location of the problem. This information can be found 
in the vehicle’s service manual.
 
Danger 
Danger indicates an imminently or potentially hazardous situation which, if not 
avoided, could result in death or serious injury to the operator or to bystanders. 
Example: 
 
Danger: If you must drive the vehicle in order to perform a troubleshooting 
procedure, always have a second person help you. Trying to drive and operate the 
diagnostic tool at the same time is dangerous, and could cause a serious traffic accident.
