The 2005 Mack Granite with 280,000 miles that I drive occasionally, stopped for a split second one day last week. I was driving down the road when it just stopped running for maybe 2/3 of a second. Being in gear and moving, it restarted itself. The lightning bolt icon came on but went out after a few minutes. Now, upon first start in the morning, the same icon comes on along with another, as well as the whistle, they stay on well after air pressure has come up, and they won't go out until you have moved the truck some fifteen feet. I can see that this is eventually going to put me beside the road. A friend who has sold heavy trucks for many years says that it is a sensor or sensor connection. Any ideas?
