How to Use Pinpoint Tests

NOTE: Do not proceed to any pinpoint test unless directed to do so.

These tests are specific for each code. However, jumping to a pinpoint test as a first step can be misleading. The tests have been written under the assumption that the system precheck has been performed and passed.

At times, running completely through the pinpoint test will not lead to problem resolution. Often, the concern is due to an intermittent connection, termination, or circuit concern. Refer to the Intermittent Diagnostics Test when situations like this arise.

It should be also noted that several circuits pass through one or more interconnections between components. These are also areas of potential concern and should be considered.
