Service bulletin SB230

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

SUBJECT : Engine overheating due to an open or not properly closed access door with electric cooling fans CONDITIONS : This service bulletin does not entitle to any reimbursement.

To prevent personal injury due to running fans, a safety system with proximity switches prevents the cooling fans from running when the access door is open or not properly closed.

To prevent this from happening, it is important to follow the guideline below:
