Consequence
Should the engine stall, a vehicle crash could occur.
Corrective Action
Cummins, in conjunction with optima bus, will notify owners and repair the engines by emc recalibration and replacement of the fuel lift pump at no charge to the customer. Owners may contact cummins assistance center at 1-800-diesels or optima bus at 1-316-779-7700.
