Mazda Fender Grounding: UPDATE
I-CAR · July 18, 2024 · Mazda
Summary
Mazda has integrated its front fender grounding guidelines into vehicle-specific Bodyshop Manuals to prevent electrical comebacks and PCM malfunctions. The procedure requires masking specific areas on the front fender stay during painting to ensure a clean metal-to-metal ground connection.
What to do on the job
Mask the designated shaded area on the front fender stay before painting, use the specified ground bolt, and apply touch-up paint to any exposed base metal only after the bolt is tightened.
How to use it
Use this document to justify the necessary labor time for masking ground locations on the front fender stay during the refinishing process, as well as the time required to apply post-assembly touch-up paint for corrosion protection. This prevents PCM failures, engine stalls, and electrical comebacks.
