The Ford F250HD 4X4 engine light comes on and.

IF THE CHECK ENGINE LIGHT IS ON---OF MAYBE EVEN OFF, IT COULD GIVE YOU CODES OR STORED CODES

WRITE THE EXACT CODE NUMBERS DOWN (NOT WHAT THEY MEAN OR WHAT SOMEONE ELSE SAYS THEY MEAN) AS THEY MAY BE INTERPRETED DIFFERENTLY DEPENDING ON WHAT THE SITUATION IS

THE CONNECTOR SHOULD BE UNDER THE DASH ON THE DRIVERS SIDE SOMEWHERE!

IT WILL LOOK LIKE THE MALE COUNTERPART TO THIS CONNECTOR IN THIS LINK

YOUR VEHICLE IS A '96---THIS IS THE YEAR OBD II BECAME A STANDARD THING

I DON'T KNOW A LOT ABOUT THE EXACTS---BY SOME WILD CHANCE YOURS MAY BE OBD I, 'CAUSE OF THE POSSIBILITY OF IT SORTA BEING EQUIPPED AS A '95 WOULD BE----THESE 2 CONNECTORS (A LARGER AND A SINGLE ONE) ARE USUALLY SORTA DANGLING IN THE ENGINE COMPARTMENT AROUND OR ON TOP OF THE DRIVER'S FENDER

IT TAKES A DIFFERENT SCANNER TO SCAN OBD I----THE CHEAP ONES (LIKE I HAVE) REQUIRE YOU TO COUNT BEEPS OR LIGHT FLASHES AND FOLLOW SEQUENCES TO RETRIEVE THE CODES (IT'S A PAIN TO GET INTO "THE GROOVE" AND MAY TAKE SEVERAL ATTEMPTS AS THE BEEPS AND "SPACES" ARE NOT EZ TO DISTINGUISH AT 1ST!)----2 BEEPS A SPACE AND 3 BEEPS (OR LIGHTS) MEANS "CODE 23" (JUST AN EXAMPLE) BUT THERE MAY ALSO BE 5---3---5 (EXAMPLE) MEANING YOU ARE TESTING A V-6 OR V-8---THEY ALL SORTA GET THROWN OUT IN A LONG LINE---AND ONLY THE "SPACE'S DURATION" AND KNOWING WHAT TO EXPECT WILL LET YOU KNOW WHAT IS A CODE NUMBER AND WHAT IS A "TEST NUMBER"

LET'S HOPE YOU HAVE OBD II UNDER THE DASH!

USUALLY WHEN I GET THE CODES---I'LL ONE AT A TIME INSTALL THEM BESIDE "obd-codes.com/" "(THE CODE)" ON A GOOGLE SEARCH

EXAMPLE obd-codes.com/p0456 SOMETIMES I HAVE TO CLICK THRU A FEW HITS---ULTIMATELY, I LIKE TO WIND UP AT THIS SITE http://www.obd-codes.com/p0456 THE "POSSIBLE CAUSES AND SOLUTIONS" AID ME THE MOST

REMEMBER IT "P", "ZERO" (NOT "O") THEN THE REST OF THE NUMBER

NOW THAT YOU ARE THOROUGHLY CONFUSED LET ME KNOW HOW IT ALL WORKS OUT!
