# Service bulletin LI54.18\-P\-067550

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.

One or more of the faults listed under 'Control unit/fault code' for the accelerator pedal \(B37\) is logged in the PTCU control unit \(N127\).
