2 - Inspect the vehicle and plan your work
CHECK THE BATTERY
Test the battery voltage to make sure it's fully charged and inspect battery terminals for tightness and any corrosion. This
only takes seconds and can save hours of troubleshooting later.
New Vehicles RARELY have a fully charged battery. This can cause many system malfunctions.
3 – Turn the Vehicle OFF or Disconnect the Battery
TURN THE VEHICLE OFF BEFORE STARTING
Be sure to turn the vehicle OFF before starting, and keep the vehicle OFF until the installation is fully completed BEFORE
the vehicle is turned on.
Note: Failure to follow these instructions may cause the AIRBAG FAULT SENSOR to become enabled. Fault
Sensors which have been enabled will require the Dealer Service Department to reset them. Dealerships often
charge a significant fee to reset the Fault Sensor.
Keep the Vehicle OFF while the Radio is disconnected to avoid a potential Airbag Sensor Fault
