Recall Campaign
December 2012
FL634A
NHTSA #12V-552

Subject: FCCC X-Line Chassis Brake Signal Diode Jumpers
Models Affected: Specific Freightliner Custom Chassis XC and XB
chassis manufactured January 21, 2010, through September 20,
2012, with certain Nexans autoelectric of America diode jumpers.

General Information
Daimler Trucks North America LLC, on behalf of its wholly owned subsidiary, Freightliner Custom Chassis
Corporation, has decided that a defect that relates to motor vehicle safety exists on the vehicles mentioned
above.
There are approximately 7,600 vehicles involved in this campaign.
Excess heat shrink used to protect the diode on certain brake and cruise control signal diode jumpers may prevent
the connectors from fully locking in place. Over time, the connectors may come loose, resulting in a possible
intermittent or continuously open circuit. Two circuits are potentially affected. One circuit disengages the cruise
control with brake pedal application, and the other circuit illuminates the brake lights with brake pedal application.
The failure of the cruise control to disengage or of the brake lights to illuminate when the brake pedal is depressed
may increase the risk of a vehicle crash.
Vehicles will be inspected to ensure the locking tabs on the diode jumpers are fully engaged and locked into place.
Additional Repairs
Dealers must complete all outstanding Recall and Field Service campaigns prior to the sale or delivery of a vehicle.
A Dealer will be liable for any progressive damage that results from its failure to complete campaigns before sale
or delivery of a vehicle.
Owners may be liable for any progressive damage that results from failure to complete campaigns within a
reasonable time after receiving notification.

Work Instructions
Please refer to the attached work instructions. Prior to performing the campaign, check the vehicle for a completion
sticker (Form WAR260).

Replacement Parts
No replacement parts are needed for this repair. NOTE: An allowance of $1.00 for black electrical tape to rebundle
the diode jumpers is included in the campaign. It should be automatically added to your claim in OWL. If filing in
QuickClaim, add this allowance to the parts section of the claim.
If our records show your dealership has ordered any vehicles involved in campaign number FL634A, a list of the
customers and vehicle identification numbers will be available on AccessFreightliner.com. Please refer to this list
when ordering parts for this recall.

Removed Parts
U. S. and Canadian Dealers, please follow Warranty Failed Parts Tracking shipping instructions for the disposition
of all removed parts. Export distributors, please destroy removed parts unless otherwise advised.

IMPORTANT: When the Recall has been completed, locate the base completion label in the appropriate location
on the vehicle, and attach the red completion sticker provided in the recall kit (Form WAR260). If the vehicle does
not have a base completion label, clean a spot on the appropriate location of the vehicle and first attach the base
completion label (Form WAR259). If a recall kit is not required or there is no completion sticker in the kit, write the
recall number on a blank sticker and attach it to the base completion label.

U.S. and Canadian dealers, contact the Warranty Campaigns Department from 7:00 a.m. to 4:00 p.m. Pacific Time,
Monday through Friday, via Web inquiry at AccessFreightliner.com / Support / My Tickets and Submit an Inquiry,
or the Customer Assistance Center at (800) 385-4357, after normal business hours, if you have any questions
or need additional information. Export distributors, submit a Web inquiry or contact your International Service
Manager.
U.S. and Canadian Dealers: To return excess kit inventory related to this campaign, U.S. dealers must submit a
Parts Authorization Return (PAR) to the Memphis PDC. Canadian dealers must submit a PAR to their facing PDC.
All kits must be in resalable condition. PAR requests must include the original purchase invoice number. Export
Distributors: Excess inventory may be returned as noted for U.S. and Canadian dealers. Export locations will pay
freight to return kits. Export Distributors: Excess inventory is not returnable.
The letter notifying U.S. and Canadian vehicle owners is included for your reference.
Please note that the National Traffic and Motor Vehicle Safety Act, as amended (Title 49, United States Code,
Chapter 301), requires the owner’s vehicle(s) be corrected within a reasonable time after parts are available to you.
The Act states that failure to repair a vehicle within 60 days after tender for repair shall be prima facie evidence
of an unreasonable time. However, circumstances of a particular situation may reduce the 60 day period. Failure
to repair a vehicle within a reasonable time can result in either the obligation to (a) replace the vehicle with an
identical or reasonably equivalent vehicle, without charge, or (b) refund the purchase price in full, less a reasonable
allowance for depreciation. The Act further prohibits dealers from selling a vehicle unless all outstanding recalls
are performed. Any lessor is required to send a copy of the recall notification to the lessee within 10 days. Any
subsequent stage manufactured is required to forward this notice to its distributors and retail outlets within five
working days.

Work Instructions
Subject: FCCC X-Line Chassis Brake Signal Diode Jumpers
Models Affected: Specific Freightliner Custom Chassis XC and XB
chassis manufactured January 21, 2010, through September 20,
2012, with certain Nexans autoelectric of America diode jumpers.

Heat Shrink Inspection and Repair
1. Check the base label (Form WAR259) for a completion sticker for FL634 (Form WAR260) indicating this work
has been done. The base label is usually located on the front wall under the dash. If a sticker is present, no
work is needed. If there is no sticker, proceed with the next step.
2. Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.
3. Locate the three diodes. See Table 2 for the location of the diodes for each body builder. (The table should
have accurate locations for the wiring harness and diode jumpers, but it is possible for the wiring harness
and diode jumpers on a specific vehicle to be in a different location than indicated below.) See Fig. 1 for an
example of the suspect diode jumpers.
Brake Diode Access Location by Body Builder
Body Builder

Diode Access Location

Fleetwood–All Units

Remove the kick panel on the left side of the steering column.

Forest River–Berkshire and
Charleston Units

Remove the eight Allen-head screws that mount the console on the left side of the drivers
seat. Gently lift the console, but do not disconnect anything from it. The diodes are down at
the floor.

Newmar–All Units

Open the front-left exterior access door; the brake diodes are immediately visible.

Thor–Palazzo Unit

Diodes are in the lower-left exterior compartment, in the corner with a P-clamped harness.

Thor–Tuscany Unit

Open the front-left exterior access door; diodes are between the floor and foam. Grab the
entire harness assembly and gently pull down to remove the diodes from the foam.

Tiffin–All Units

Locate the front power distribution module (PDM), either behind the center console or in
the lower-left exterior compartment.
If the PDM is behind the center console, the diodes are near the throttle pedal, against the
bulkhead.
If the PDM is in the lower-left exterior compartment, the diodes are in the upper area, near
the steering wheel.

Winnebago–All Units

Open the front-left exterior access door; the diodes are to the left.
Table 2, Brake Diode Access Location by Body Builder

4. Cut the black tape around the wiring harness and diode jumpers, then lightly pull on each side of the diode.
5. If no diode comes apart and all three are securely connected, no further work is needed. Go to step 11.
If one or more diodes come apart, continue with the next step.
6. Trim the heat shrink from one side. See Fig. 2 for an example of excessive heat shrink around the diode
locking tab. Fig. 3 shows a brake diode with properly applied heat shrink.
7. Push the diode locking tabs together.
If a clicking sound is heard, no further work is needed. Go to step 8.
If a clicking sound is not heard, trim additional heat shrink from the diode locking tab and push the locking
tabs together.

8. Complete steps 4-7 for all three diode jumpers.
9. Tape the diode jumpers on the wiring harness and place the assembly where it was found earlier.
10. If an access cover was opened or removed, close or install the cover.
11. Clean a spot on the base label (Form WAR259), write recall number FL634 on a red completion sticker (Form
WAR260), and attach it to the base label.
