Hello All, I've got a 2018 5.0 Lariat F150 and had to rewire my rear axle, extending the harness for a 4-link conversion. I forgot to put the Electronic Parking Brake into service mode. I finished the rewiring and everything (WSS's and EPB) all seem to function correctly and you can hear the EPB engaging when switched, but I'm left with this error message. I cannot get the EPB in or out of service mode. I really want to clear this error because it deactivates all the drivers assistance features like cruise control, hill descent, etc. Any ideas on how to clear this code? Can't find anything on my OBD fusion app, either.

 

If your current reader does not see the code, you need to get FORScan. You can try leaving the battery disconected for 30 min.

 

It's odd, I have the paid version of OBD fusion WITH the paid 'extended features' pack and it still doesn't seem to be picking this up. I do have the OBD/forscan cable and a laptop, just never gotten around to using any of it. I can use forscan to reset this code?

 

If you can see a code and it can be cleared, then FORScan can do it. If you haven't corrected the issue, that DTC may return.

 

Update - i found out my bluetooth OBD reader can't access the MS-CAN protocol of my ABS module, so I couldn't see the code. I had my ford tech buddy read the code and it showed the left EPB had an open circuit. Turns out the plug on the caliper had come loose. Good times.
