Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
