Self-Diagnostic Tests
CAUTION:
In following self-diagnostic tests, turn ignition switch to OFF position before disconnecting or connecting any components.
NOTE:
Self-diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box (DRB). A generic scan tool may not be capable of performing all necessary test functions.
Perform VISUAL INSPECTION before proceeding with any self-diagnostic tests. Begin diagnosis with TEST 1A; DO NOT proceed to any other self-diagnostic test without first performing TEST 1A.
