G552800t35 : CHECK THE SUPPLY CIRCUIT FOR HIGH RESISTANCE 1. Key off. 2. Disconnect the ECM connector, C101. 3. Measure the resistance between: C71, harness side C101, harness side Pin 03
Pin J1
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 circuit. For additional information, refer to the wiring diagrams. Clear any DTCs, test the system for normal operation. G552800t36 : CHECK THE SUPPLY AND SIGNAL CIRCUITS FOR SHORT 1. Key off. 2. Disconnect the ECM connector, C101. 3. Key on, engine off. 4. Measure the resistance between: C71, harness side C71, harness side Pin 04
Pin 03
Is the resistance greater than 100 Kohms? -> Yes GO to Pinpoint Test G552800t37.
-> No |
