Is the resistance greater than 100 Kohms? -> Yes GO to Pinpoint Test G552800t16.
-> No REPAIR the short circuit. For additional information, refer to the wiring diagrams. Clear any DTCs, test the system for normal operation. G552800t16 : CHECK THE INTAKE AIR SHUTOFF THROTTLE RETURN 1. Measure the resistance between: C39, harness side C100, harness side Pin 01
Pin F2
Is the resistance less than 10 ohms? -> 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): - ECM connector - ECM
-> No REPAIR the high resistance. For additional information, refer to the wiring diagrams. Clear any DTCs, test the system for normal operation. G552800t17 : CHECK THE SIGNAL AND RETURN CIRCUITS FOR SHORT 1. Key off. 2. Disconnec the ECM connector, C100. 3. Key on, engine off. 4. Measure the resistance between: C39, harness side C39, harness side Pin 06
