SUBJECT: Spartan Motors Chassis, Inc. has determined a defect relating to the cruise

control system may exist in certain recreational vehicle chassis.

Bulletin RSB11-500-001 is superseded by bulletin RSB11-500-001A

due to kit changes and revision of assembly process. Any vehicles

repaired under bulletin RSB11-500-001 will not require any additional

work.

CONDITION: 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.

APPLIES TO: This bulletin applies to recreational vehicles chassis assembled by Spartan

Motors Chassis, Inc. during vehicle dates of manufacturing of 10-4-2007

and 3-10-2011

CORRECTION: 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.

LABOR ALLOCATION: 2.0 hrs.

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.
