NHTSA recall 12V574000

What's wrong: The vehicles are equipped with diode jumpers that may come loose in their connectors resulting in an open circuit. Two circuits are affected: the one that disengages the cruise control with brake pedal use, and the one that illuminates the brake lights with brake pedal use.

Why it matters: Failure of the cruise control to disengage when the brakes are applied may increase the risk of a vehicle crash. Without the brake lights illuminating when the brakes are applied, the driver's intent is not communicated, increasing the risk of a crash.

The fix: Daimler trucks (dtna) will notify owners on behalf of thor, and freightliner dealers will inspect the diode jumpers to make sure they are fully locked in place and will correct the vehicles as needed. The recall is expected to begin January 28, 2013. Owners should contact dtna warranty campaigns…
