NOTE: For instrument cluster circuit and terminal identification, see WIRING DIAGRAMS .

NOTE: For diagnosis and testing of systems not covered in this article, manufacturer recommends using DRB scan tool to check Chrysler Collision Detection (CCD) and/or Powertrain Control Module (PCM) circuits. For CCD data bus testing, check for opens and shorts in CCD data bus circuits. See DATA LINK CONNECTORS article in WIRING DIAGRAMS. For more information on scan tool and PCM diagnostics, see SELF-DIAGNOSTICS - CHEROKEE article in ENGINE PERFORMANCE.
