•
•
If the OPDS is initialized (the indicator light is off) and it passed all the inspection items (INSPECTION

To dry the seat, do this:
- Close the vehicle windows and sunroof.
- Start the engine and run the HVAC at its highest heat setting and make sure the A/C is on.
- Aim the vents at the OPDS sensor area.
- If you can’t safely run the vehicle to dry the seat, use a shop fan aimed directly at the OPDS sensor.
- Try to initialize the OPDS every 30 minutes. If it doesn’t initialize, continue drying the seat and try again
in 30 minutes. Most seats will dry within 1.5 hours.
