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...

Fault Condition: FMI 3 indicates that ashort to power has been detected at connector Apin 3 of the Engine Management Systems (EMS)Module. Possible repairs: Turn the ignition key OFF first. 1) If code SID 18 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the Water in Fuel Valve harness connector and wires for frayed or loose connections.2) Disconnect connector A at the Engine Management System (EMS) Module and the Water in Fuel Valve Relay connector. Turn the ignition key ON. Measure the voltage between Engine Management System (EMS) Moduleconnector A pin 3...

Fault Condition: FMI 4 indicates that a short to groundhas been detected at connector A pin 3 of theEngine Management Systems (EMS) Module. Possible repairs: Turn the ignition key OFF first. 1) If code SID 18 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the Water in Fuel Valve harness connector and wires for frayed or loose connections.2) Disconnect connector A at the Engine Management System (EMS) Module and the Water in Fuel Valve Relay connector. Check for continuity between the Engine Management System (EMS) Module connector A pin 3 and a...

Fault Condition: FMI 5 indicates that an open circuit has beendetected in the Water in Fuel Valve Circuit. Possible repairs: Turn the ignition key OFF first. 1) If code SID 18 is not set, wiggle the harness and connectors to try to set the code. Visually inspect the Water in Fuel Valve harness connector and wires for frayed or loose connections.2) Remove fuse 2 at the Engine Power Distribution Module and disconnect the Water in Fuel Valve Relay connector. Check for continuity between pin B at fuse 2 in the Engine Power Distribution Module and pin 4 of the Water...

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 2 will set. Possible repairs: Turn the ignition switch OFF first. 1) Disconnect the harness electrical connector from Fuel Injector Unit #2. 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 #2 is faulty and must be replaced.2) Disconnect the...
