Inertia Fuel Shutoff Switch: Testing and Inspection
The technician should be aware that diagnosis and testing of the Inertia Fuel Shutoff (IFS) Switch should begin at the Powertrain Management System
level, where testing begins with Diagnosis by Symptom, and is narrowed to testing of a "specific" subsystem and it's related wiring and components.
Following the appropriate diagnostic routines may prevent misdiagnosis and unnecessary component replacement. Refer to Powertrain
Management/Testing and Inspection/Procedures.
