WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 1991 Plymouth Colt Vista, 1991 Plymouth Colt, 1991 Mitsubishi Mirage, 1991 Mitsubishi Galant, and 1991 Mitsubishi Eclipse. However, it is still accessible from the selected car via links, so may be relevant.
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.
