Fault Condition: If the Engine Management System (EMS) Module detects a fault in the electrical circuit while attempting to operate the Fuel Injector Unit, the Electronic Malfunction Lamp (EML) will turn ON and code SID 1 will set. Possible repairs: Turn the ignition switch OFF first. 1) Disconnect the harness electrical connector from Fuel Injector Unit #1. Check for continuity between the pins 1 and 2 of the Fuel Injector Unit #1. If the resistance is NOT between 0.9-5.2 Ohms at 68°F (20°C) or 1.5-5.8 Ohms at 218°F (103°C), Fuel Injector #1 is faulty and must be replaced.2) Disconnect the...

Fault Condition: If the Engine Management System (EMS) Module detects an open, short to ground or short to voltage while attempting to operate the EGR Control Valve, the Electronic Malfunction Lamp (EML) will turn ON and code SID 146 will set. Code SID 146 will also set if EGR flow is not within the proper range for the current engine operating conditions. If the Engine Management System (EMS) Module detects a short circuit to ground in the EGR Control Valve high side drive circuit, the EMS Module will turn OFF the high side driver and the driver will remain OFF...
