G552275t45 : CHECK WHETHER THE SHORT CIRCUIT TO GROUND IS IN THE 1. Key off. 2. Disconnect the fuel injector 1 (INJ0) connector, C44. 3. Key on, engine off. 4. Measure the resistance between: C101, harness side Battery
Pin M3
Negative terminal Pin L3
Negative terminal
Are the resistances greater than 100 Kohms? -> Yes An intermittent fault may be present in the wiring harness. Visually check for chaffed wires or other physical damage to the harness. If no fault is found in the circuit, suspect the following component(s): - Fuel injector 1 (INJ0)
-> No REPAIR the short circuit. For additional information, refer to the wiring diagrams. Clear any DTCs, test the system for normal operation. G552275t46 : CHECK THE FUEL INJECTOR CIRCUIT FOR SHORT CIRCUIT TO 1. Measure the resistance between: C101, harness side Battery
Pin M3
Positive terminal Pin L3
Positive terminal
Are the resistances greater than 100 Kohms? -> Yes An intermittent fault may be present in the wiring harness. Visually check for chaffed wires or other physical damage to the harness. If no fault is found in the circuit, suspect the following component(s): - Fuel injector 1 (INJ0) connector - Fuel injector 1 (INJ0) - ECM connector - ECM
-> No GO to Pinpoint Test G552275t47.
