Title: Electrochromatic rear view mirror
Post by: VaerO on April 01, 2014, 12:06:44: :(

Dita may have hit her first bump!! I think the "Electrochromatic rear view mirror" (auto dim) may have stopped working. I noticed a lot of glare from cars behind me tonight as it wasn't dimming the on coming light. It also won't respond when I press or hold on the power button, its stuck on on.

Does anyone know any troubleshooting technquies?

I'd do the old battery disconnect job.

Give it a go.

Learn something new every day. So is there a ruff time i should leave it unconnected?

Some info 4 u.

2010 BCM.pdf - Google Drive (https://drive.google.com/file/d/0B8ANHWfNw-qjMDA3MGpGbWVvS1U/edit?usp=sharing)

It's the latest model I have info for, so later models most likely do additional things as well.

Strange that there's no mention of the auto-dimming RVM - maybe it truly is a standalone 12V feature.

Still, won't do any harm to still try the battery disconnect trick.

Post by: Phil №❶ on April 02, 2014, 08:55:57: This info is for FD 2010 model which is where my data ceases. Now if someone had a GD equivalent, that would be nice.

Or as Agnes Brown says, "That's nice." :lol:
