I’m having a recurring issue with my 2024 Mustang GT and wanted to see if anyone else has experienced the same thing.
The driver-side/left low beam randomly turns on by itself after the car is shut off and locked. This first happened back in June. I took it to Ford, and they found DTC B1D00:62 stored in the LDCMA (Lighting Driver Control Module A). According to the repair order, they performed PMI/reprogramming of the headlamp-mounted LDCMA, cleared the codes, and the issue went away.
Now, a few months later, the exact same problem has returned.
This time it happened after it had been raining. The car was parked and locked, but the driver-side headlight kept turning on by itself intermittently for several hours. Unlocking and locking the car would sometimes make it go away temporarily, but it would come back again. The problem continued until around 4 AM, and by the morning the headlight was off and everything appeared normal again.
I also currently have an open Engine Harness Ground Eyelet Replacement recall on the car, so I’m wondering if an intermittent ground, moisture/water intrusion, LDCMA issue, or wiring/connector problem could be causing this.
Has anyone else with an S650 Mustang had:
Any similar experiences or fixes would be appreciated.

Has anyone else with an S650 Mustang had:
- One headlight turn on by itself while the car is off/locked?
- B1D00:62 or other LDCMA/LDCMB codes?
- A similar issue after rain or washing the car?
- A dealer replace the LDCMA/headlight module instead of just reprogramming it?
Any similar experiences or fixes would be appreciated.
