Section 91 (Engine Controls - System/Component Tests - 5.9L Diesel): Introduction
WARNING: This page is about a different car, the 1995 Dodge Pickup and 1995 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Before testing separate components or systems, perform procedures in BASIC TESTING - 5.9L DIESEL article in the ENGINE PERFORMANCE section. Since many computer-controlled and monitored components set a diagnostic trouble code if they malfunction, also perform procedures in TESTS W/CODES - 5.9L DIESEL article in the ENGINE PERFORMANCE section.
NOTE:
Testing individual components does not isolate shorted or open circuits. Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless otherwise instructed in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.
