C30, harness side C100, harness side Pin 01
Pin D1
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): - FRP connector - ECM connector - FRP - ECM
-> No REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. Clear any DTCs, test the system for normal operation.
