• This section covers electrical system service of the PGM-FI system. For other service and fuel supply system, see Fuel System section (page 7-2).• A faulty PGM-FI system is often related to poorly connected or corroded connectors. Check those connections before proceeding.• The PGM-FI system is equipped with the Self-Diagnostic System (page 4-4). If the MIL comes on, follow the Self-Diagnostic Procedures to remedy the problem.• When checking the PGM-FI, always follow the steps in the troubleshooting flow chart.• The PGM-FI system is provided with fail-safe function to secure a minimum running capability even when there is any trouble in the system. When any abnormality is detected by the self-diagnosis function, running capability is secured by making use of the numerical values of a situation preset in the simulated program map.It must be remembered, however, that when any abnormality is detected in an injector, the fail-safe function stops the engine to protect it from damage.• For PGM-FI system location (page 4-3).• For PGM-FI system diagrams (page 23-2).• Use a digital tester for PGM-FI system inspection.• The following color codes are used throughout this section.
