Notes and Important Messages
Notes
A NOTE provides helpful information such as additional explanations, tips, and comments.
Example:
Note: In general, vehicle idencaon numbers are standardized - all contain 17 characters. VIN characters may
be capital leers A through Z and numbers 1 through 0; however, the leers I, O and Q are never used in order to
avoid mistakes of misreading. No signs or spaces are allowed in the VIN.
Warning
 indicates a hazardous situation which, if not avoided, could result in minor or moderate injury to
the operator or to bystanders.
Example:
Warning: Retrieving and using DTCs for troubleshooting vehicle operation is only one part of an overall
diagnosc strategy. Never replace a part based only on the DTC denion. Each DTC has a set of tesng procedures,
instrucons and ow charts that must be followed to conrm the locaon of the problem. This informaon 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 troubleshoong procedure, always have a second
person help you. Trying to drive and operate the diagnosc tool at the same me is dangerous, and could cause a
serious trac accident.

This option is used to access vehicle-specific subsystem and component tests. Available test vary by
vehicle manufacturer, year, and model. During the actuation test, the tablet outputs commands to the ECU
in order to drive the actuators, and then determines the integrity of the system or parts by reading the ECU
data, or by monitoring the operation of the actuators, such as switching a injector between two operating
states.
Tap Actuation Test on the test function selection screen, the system will display as follows:
