FORD 2007 F-550 v.2 - Manual (Page 13)

Many lights will illuminate when you start your vehicle to make sure the
bulbs work. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
If your vehicle is equipped with a diesel engine, it has a unique cluster;
refer to Starting the engine in your 6.0 Liter Power Stroke Direct
Injection Turbo Diesel Owner’s Guide Supplement.
Service engine soon:
The Service engine soon indicator
light illuminates when the ignition is
first turned to the ON position to
check the bulb. Solid illumination after the engine is started indicates the
On Board Diagnostics System (OBD-II) has detected a malfunction. Refer
to On board diagnostics (OBD-II) in the Maintenance and
Specifications chapter. If the light is blinking, engine misfire is occurring
which could damage your catalytic converter. Drive in a moderate
fashion (avoid heavy acceleration and deceleration) and have your
vehicle serviced immediately.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Electronic throttle control:
Illuminates when the engine has
defaulted to a ’limp-home’ operation.
Report the fault to an authorized
dealer at the earliest opportunity.
On vehicles equipped with a message center, “ENGINE FAILSAFE
MODE” will be displayed, refer to Message Center in the Driver
Controls chapter.
