Self-Diagnostic System

Use Chrysler Motors code charts when using Chrysler's Diagnostic Readout Box (DRB-II). If DRB-II is not available or if working on a Mitsubishi Motors vehicle, system diagnosis can only be accomplished using a voltmeter or appropriate scan tester. To diagnose Chrysler Motors and Mitsubishi models using a voltmeter, see ENTERING ON-BOARD DIAGNOSTICS (USING VOLTMETER)  in this article.
