Service bulletin ENP-723

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

The Agility service team has identified a potential issue related to the fuel system driveaway protection circuit on Tico compressed natural gas (CNG) tractors. Frequent starter engagements and exposure to high current in the starter circuit may cause the electronic control unit (ECU) to prematurely fail. ECU failure will lead to a no crank/no start condition. Agility has designed a wiring harness to remedy this condition. As a precautionary measure Agility is also supplying a replacement ECU.
