Battery Coolant P2E46 Code

[MATTYs]

Hello All! Check engine light on my 23 Rubicon. 403 miles. P2E46 Battery Coolant Just got it back from dealer having hybrid battery replaced. . Waiting on dealer to "fit me in" Figured maybe they forgot to fill it, maybe air in line. No obvious leaks. Filled Reservoir three times. Keeps going down. Does anyone else hear the fluid in the battery. I can hear it flushing around inside Battery case.

Sounds like they didn't do a vacuum fill of the system to purge the air out. It's a great way to kill the ECH and possibly the pumps if it goes on long enough. The sooner they get it in and get the system filled properly, the better.

After filling the reservoir 4 times the light went out, or burnt out...lol. No issues since then. Must not have been filled correctly. I did let the dealer know.
