Does the never going away TPMS error result in a parasitic drain on my battery? It's the error where all 4 tire pressures show as blank.
The HFL has been disconnected years ago and I've only had this new battery for 8 months. Besides this TPMS error I also have the service required msg that hasn't been reset.

 

unlikely.. have you done a parasitic draw test to at least figure out which circuit it's coming from?

 

No, not yet. I also have a USA spec BT module inside my trunk. I might as well remove it since it failed months ago and might be contributing to the drain.

 

definitely suspect and possible..

 

I did a draw test using my multi-meter and the culprit is the 'Interior Light' fuse (7.5 A). It's currently drawing .25 amps while the car is shut off.
What could be causing the issue as my interior lights all work fine? I've no issues with the: front overhead light, rear dome light and both front door panel lights.

The only thing I notice is that one of the two rear dome light bulbs seem dimmer than the other.
