Bulletin 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 2007 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. Revised units affected by year.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
