Official summary
Service Update. On certain vehicles, equipped with a 3.0L diesel engine (RPO LM2), false failures could result in the check engine light to turn on intermittently, particularly in cold weather, during gentle or slow driving, and when both the front and rear HVAC systems are in use. Dealers are to reprogram the engine control module.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
