G549822t273 : CHECK THE INERTIA SWITCH TO ECM CIRCUIT FOR SHORT 1. Measure the resistance between: CR02, harness side Battery
Pin 03
Positive terminal
Is the resistance greater than 100 Kohms? -> Yes GO to Pinpoint Test G549822t280.
-> No REPAIR the short circuit. For additional information, refer to the wiring diagrams. Clear any DTCs, test the system for normal operation. G549822t280 : CHECK THE INERTIA SWITCH TO ECM CIRCUIT FOR HIGH 1. Disconnect electrical connector, PI41. 2. Measure the resistance between: CR02, harness side PI41
Pin 03
Pin 15
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): -Inertia switch connector -Inertia switch - 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.
