Instrument Panel Switch Functional Check and Replacement

This vehicle is equipped with a Supplemental Restraint System (SRS). Before performing any work near the airbag module, steering column or instrument panel, disable the SRS to prevent injury from accidental deployment (refer to Airbags - General Information section). SRS wiring can be easily identified by its yellow insulation.
