Using FORScan I found a DTC that I was unable to find much information about other than there is a Kubota tractor model that uses the same number.

B2320 which describes it as 'driver mirror horizontal position sensor circuit failure'. Obviously sounds like something wrong with the side mirror but also found one source saying it was to do with the air bag.

Any ideas? Any techs? Pls help.

 

Do we have any techs here that I could PM so they see this?

 

Does your driver side mirror move in all directions and is there an amber warning light on your cluster for the air bag?

Mirror moves in all directions but it does not seem very solid, quite a bit of clicking.

No warning lights or CELs on the dash.

 

Do you have memory mirrors? Basically it's an option where your seats, mirrors and such remember a programmed setting every time you start the vehicle, if someone else has used it last and changed the settings, you can press a button on the door to go back to your preset.

If the answer is no to the memory query, you can chalk up the DTC to Forscan being a beta program. (BETA=IN TESTING) You can't trust it to be completely accurate.

Yes, memory mirrors with the seats. I've removed the driver seat to replace heater element in the past. I R&R'd the connections on the seat but didn't find or see anything wrong.

 

Are you sure that is the correct code? I have access to alldata and I see all "b" codes, that one is not available.

 

Does this help:

 

Was just going to post that very test step from the manual. Op where it mentions DSM, it's talking about the driver seat module.

Run those resistance checks and report back what you find.

I got it based on your recommendation, actually. $20 on USB drive. Copied to internal drive, never need to plug anything in to run it.
