When I was recently working on some diagnostics of my Evo X (2014 MY), I noticed there was a B2102 (ignition switch start position circuit high) code stored in the ECU. When I brought the car to my dealer for service, they saw this code, and simply cleared it and told me I'm good to go.



I did ask the master tech there though. He told me that this code could be stored because at one point the battery was not supplying enough voltage, which could be a sign that the battery is going out (my Panasonic is 3-year-old).

Do you guys have any insights about this? Do I need to be slightly concern about anything?

Thanks in advance for any inputs.

Edit: I have found out the reason: Solved: B2102 code stored because of remote starter

 

Could be a mix of use (dd?) and weather (cold). Nothing to lose sleep over though. Depends on how long you want to wait to change it. Could be just a "glitch in the matrix " as I like to call it. But if it bothers you that much, have the battery tested.

 

I ordered a jump starter from Amazon just to be safe. Here, towing a lowered vehicle can cost as much as C$1,000.

However, I'm glad if this is irrelevant to anything else. If it's not related to things like ignition and electric circuits, I won't lose sleeps.
