Diagnostic Trouble Code Identification
NOTE:
Diagnostic information applies to 1996-02 models with 6.0L engine (No. 120), equipped with Motor Electronics Sequential Fuel Injection (ME-SFI). For diagnostic information availability, see MODEL IDENTIFICATION (1996-02)
table.
Use DTC identification to identify possible cause. Some diagnostic information is identified by chassis/model number. See MODEL IDENTIFICATION . To further understand DTC diagnosis and/or diagnose intermittent failures, see DTC DESCRIPTION under appropriate DTC. If vehicle is experiencing a communication failure (no communication at all), see SYSTEM & COMPONENT TESTING (ENGINE 120) article and perform appropriate tests.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
