Hey all,

So I have been trying to access engineering test mode on my 2013 F-150 XL (basic dash, nothing fancy). I used to be able to access this without a hitch until the last 2 days. For my model it used to be hold the reset button in while key in ignition but off for 5 seconds, then while still holding in reset button turn the key to run but not start the engine and hold for 5 more seconds. then it would enter test mode.

now it won't do it for reasons unknown to me. All i get is a message that says 'turn off to save battery" and it is super annoying. anyone know how to fix this?

thanks.

 

Could be the battery is low, try putting it on a charger for a bit and see if it changes.

 

that's a good and valid consideration but i know 100% it's a good battery. just bought it last year. Dekra battery. Good stuff. It's strong.

 

Battery is only as strong as the BMS allows it to be. Well documented problem with this gen truck. Connect a charger and try again.

 

okkkk if you say so. only because you have a proven track record on here of knowing your ****. LOL. thanks man i will try it out when i decide to get off my quarantined ***.
