My parents were up over the weekend and my dad brought his truck up. He has been working remote most of the winter so his truck didn't get driven much and the batter died a couple times. Someone had unplugged his Edge and never put it back.

2006 F150 5.4 Gotts + k&n, all stock.

I plugged it in and set it to a regular level 2 setting, he calls this evening after driving 10mi with some problems.

1) No cruise control
2) P060< dtc showed up (check engine light on)
3) code 202 P1635 [Tire / Axle Ratio Out of Acceptable Range] (wrench light on)

I cleared codes and went for a test drive. The speedo was reading 30mph while the gps was at 18mph....
Cleared codes, reset Edge back to stock, unplugged battery and stood on the brakes for 30 seconds. Lights still came on....
Set edge to Level 1 and reset tire size to 2473 so the speedo matched GPS. Lights still on...

He just finished a 200mi drive home and had no issues, city driving, hwy, and mountains. lights are still on


Ford Dealership said his PCM was fried and it'll be $900 for a fix.
What's the procedure for buying them? Same year/motor/trans? Is there more wiggle room than that?

He was also told that his cam phasers are starting to go... they sound fine, no unusual noises or rattling. But the dealer wants $2800 to replace them and the PCM...

His truck has about 94k mi on it, but is a fully loaded Fx4 screw/flareside. I don't think he wants to trade it in yet since it's fully paid off.
What would you guys do?

 

anyone?

 

You can by a computer and have it towed to the dealer for a re flash. Take the old one with. But if you have a programmer on it in the past it may be best to have them download the program from ford and finish it.
