  • 2008 F-SUPER DUTY- LIGHTING ON SNOW PLOW EQUIPPED VEHICLES – BUILT BEFORE 04/18/2007
Publication Date: April 19, 2007

FORD:
2008 F-Super Duty

ISSUE:

2008 F-Super Duty vehicles are equipped with a smart junction box (SJB) and it's function is to provide protection against excessive current loads, typical of a short circuit, by shutting down circuit operation. The SJB strategy may interpret the switching between Ford headlamps and aftermarket snowplow headlamps, and vice-versa, as a short-to-ground, causing the power feeding a headlamp circuit through the SJB to be turned off.

ACTION:

Reprogram the SJB to the latest calibration using IDS release 48.9 patch 9 and higher or 49.1 patch 1 and higher. This new calibration is not included in the VCM 2007.5 DVD. Calibration files may also be obtained at www.motorcraft.com.

WARRANTY STATUS:

Eligible Under Provisions Of New Vehicle Limited Warranty Coverage
IMPORTANT: Warranty coverage limits/policies are not altered by a TSB. Warranty coverage limits are determined by the identified causal part.
