NOTE: Self-diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box-III (DRB-III) scan tool. If using a generic scan tool, ensure scan tool is OBD-II certified. A generic scan tool may not be capable of performing all necessary test functions.

NOTE: Sensor ground circuits may be identified as sensor return circuits.
