RAM EVIC Cluster Upgrade. Brake light out issue, HELP

[javier_si04]

Hello everyone,
I just swap the small cluster and replace with the 7 inch EVIC cluster for my Ram yesterday, first think I notice was a brake light out message. I checked both brakes and are working fine. Anyone had this issue before and did you fixed it? I didn't have the massage on the old cluster. Help Guys.

Thank you,
Javier.

do you have LED bulbs in your brake lights. The 7 inch EVIC's are much more sensitive than the original cluster.
Cycle your brake lights a dozen times then shut the truck off and turn it back on see if the message is still there.
It fixed my turn signal issue.

Do you have any led bulbs installed in your truck??? It known that the 7” cluster is a lot more sensitive to added led bulbs then the smaller cluster.

Same issue and same upgrade. I have license plate and backup light out messages. Led upgraded. Surprised as the license plate are diode dynamics. The taillights have resistors, don't recall the setup on the 3rd brake light but quite certain they had resistors as well. Likely have to enable led with alphaobd to eliminate the dropout messages.

No, I don't.

Check your third brake light and see if it’s out.

Sometimes if you just clear faults with alpha obd they go away. Try that if you have alpha.

I got it, thanks everyone. Yup the 3rd brake light is out.

Yes I need to buy the alfaobd too

Interesting. No blown lights, but also no new messages after the first day of back up light out errors.
