Resetting the Inertia Switch

Inertia Switch Reset

Inertia Switch Location:

The inertia switch has to be reset manually once it has been triggered. The inertia switch is located under the hood on the right hand side of the bulkhead (view from front bumper). In the event of an impact registering at greater than 14G the Inertia Switch goes open. This open removes the voltage from X254 pin 21 at the BC1 (J3 54-pin Natural connector). The trigger of the inertia switch causes the BC1 to unlock doors and disables the fuel pump. In the event of the inertia switch being triggered in an accident, the doors will unlock, the windows will open, the interior lights will be illuminated and the hazard warning lights activated. The vehicle will also be unlocked if the inertia switch is tripped from ignition position 1. If a valid key is recognized in the ignition (EWS) when the vehicle is central arrested the locks move to the unlocked state.
