1 SUBJECT: Spartan Motors Chassis, Inc. has determined a defect relating to the cruise control system may exist in certain recreational vehicle chassis. Bulletin RSB is superseded by bulletin due to kit changes and revision of assembly process. Any vehicles repaired under bulletin RSB will not require any additional work. CONDITION: APPLIES TO: CORRECTION: Certain recreational vehicles chassis produced by Spartan Motors Chassis, Inc. may exhibit an inadvertent, increase in vehicle speed after the vehicle's cruise control is set. When the brake is applied and released, the cruise may resume and the vehicle speed may continue to increase. This bulletin applies to recreational vehicles chassis assembled by Spartan Motors Chassis, Inc. during vehicle dates of manufacturing of and The analog steering wheel switch pods are being replaced with digital switch pods; and the Spartan Control Module (SCM) will be reprogrammed to support that change.

3 Note: This procedure has three main elements to complete for successful application of the remedy. Replacement of the steering wheel switch pods. Repinning of the control module. Reprogramming of the control module. 2. Disconnect vehicle power by disengaging the power disconnect switch. a. This is located at the rear of the vehicle or, in the service center at the right rear of the vehicle. 3. Remove the control module fuse located in the Power Distribution Center (PDC). a. The PDC location is designated by the final stage manufacturer so it can be in any of several locations about the chassis. i. Typical locations are: near or under the battery storage tray In one of the outside storage compartments, typically towards the rear of the vehicle on either side. Within its own access panel; similar to the outside storage compartments except smaller. b. One of two fuse blocks may have been used: i. For models with 2010 emissions engine: remove the 15A fuse at F11, see FIG. 4-1A. ii. For models with pre-2010 emissions engine: remove the 15A fuse at F10, see FIG. 4-1B Page 3 of 12 ENG-FR-040
