Pin 01
Negative terminal
Is the resistance greater than 10 Kohms (+/-10%) ?
-> 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
-> No
Repair the short circuit. For additional information, refer to the wiring diagrams. Clear any DTCs, test
the system for normal operation.
