# Service bulletin TSB2018\-1043

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

During a routine truck delivery inspection a malfunction of the air flow restriction indicator light was detected. Our investigation determined that the malfunction was introduced in 2010 with the launch of the new ISSPRO gauge cluster. The new dash gauge cluster changed the requirement for air flow sensor signal from active high to active low. This malfunction went unnoticed until now due to our published air filter routine maintenance requirements and the air filter?s longevity.
