SECTION VI

TROUBLESHOOTING

2005     Tech 2 User’s Guide     VI - 1

Troubleshooting

Section VI is a general troubleshooting guide for all vehicle applications of the Tech 2 scan tool. Some of
the information may differ for your particular vehicle application.

If the Tech 2 appears to be operating abnormally, refer to this section—particularly the diagnostic charts
and troubleshooting tables beginning on page VI-6—for probable causes and solutions.

The following two types of self tests are available on the Tech 2:

• Power On Self Test (POST) checks the major functions of the Tech 2 at power-up.

• Self Tests check the major and minor functions of the Tech 2.

If errors are detected, a Tech 2 malfunction is present which may result in vehicle misdiagnosis.

For customer support, refer to the Customer Support Overview on pages ii and iii of this user’s guide.

NOTICE

The CANdi module should not be connected while running Tech 2 and VCI self tests.
