I left the key in the ignition switch, switch on and the next morning the 4×4 and fwd lights flash. The 4×4 don't react if I select 4h or 4l.

I had the truck at a Ford dealer to scan for codes, no fault codes.

How can I test the Esof module.

Thanks

JUST A THOUGHT

REMOVE THE BATTERY AND CHARGE IT

"KEY WORD" IS REMOVE IT

NOW WITH A "FRESH FULLY CHARGED BATTERY"

HOOK IT BACK UP

YOUR COMPUTER MAY RESET WHEN IT WAS DISCONNECTED AND NOW SENSES 12 VOLTS

LEMME KNOW IF THIS WORKED!
