Steering Lock Fault / Malfunction Service Now! Car Won’t Start! Ford Mustang s550 2015-2020

[Carlos990815]

Hi All,

Does anyone have this issues or has had this issue in the past?
I have heard of it, but there isn’t really much info on why this could happen

Fault Code Present and Coming from Body Control Module (BCM) on my 2017 Mustang Shelby GT350 is:

B1026:87-0A (Steering Column Lock)

Funny Part is my Gt350 doesn’t have Enhanced Security Package, so therefore there’s no Steering Column Lock, but still I’m getting this error.
Car will not Crank up or even attempt to turn the engine over. Only thing you can hear is a loud clicking noise from the (BCM) and that’s it.

What i have attempted:

Replaced the OEM Battery i put a brand new one in, 96R Group 590 CCA.

Checked all fuses and connections on bcm and pcm they all seem fine as well as relays.

Performed a Battery Recognition Test or Battery Module Reset so it detects the New battery.

General reset to each module on board and cleared all dtc’s stored.

ALL I HAVE GOTTEN IS NO START.


Here is aLink to an Official NTHSA opened for this issue for 2020 Ford Mustang:

Did you purchase the car used or are you the original owner?

When was the last time the car was started PRIOR to the problem (getting the error)? Last time meaning days, weeks, months....

It seems to be a fault related to the BCM.

There's an SSM out for this specific issue if you haven't already resolved it (or if anyone else runs into it): SSM 49044 Some 2020 Mustang vehicles may exhibit a concern of being unable to crank the engine. This will be accompanied by a B1026 DTC and a message in the instrument cluster indicating a steering lock module fault. This may be due to a fault with the body control module (BCM) software. Reprogram the BCM to correct this condition.

There is also SSM 48651 specific to the Mustang:
