Component Tests and General Diagnostics

Underbody Inspection

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
2. Inspect for obvious floor pan deterioration.
3. Inspect for loose dirt and rust around the inside of the access holes of the floor pan reinforcement member. Loose dirt and rust are the first indication that corrosion may exist in hidden areas. Repairs may be required before performing the final cleaning and protective treatment.
