CAUTION: The two circuits between the anti-lock brake control module and each brake anti-lock sensor are twisted together at intervals of approximately one turn per 25.4 mm (1 inch) . When circuits are repaired, be sure to restore the turns to ensure proper shielding.

NOTE: Do not proceed to any pinpoint test unless directed to do so. These tests are specific for each DTC. However, jumping to a pinpoint test as the first step can be misleading. The tests have been written under the assumption that the System Pre-Check has been performed and passed. See: Initial Inspection and Diagnostic Overview\System Pre-Check

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