Might want to check for codes before resetting the BCM...
To reset the BCM...
Disconnect battery cables (Negative first, then Positive) after making sure the security is disarmed.
I leave it disconnected about 20-30 min, then just before reconnecting, briefly touch the Pos & Neg battery cables together.
Reconnect the battery cables (Positive first, then Negative).
The BCM should be reset.
If it has changed due to the newer ECMs, I am unaware of the changes... Someone will surely correct me...

Probably got a connector wet between the BCM and ABS modules, that caused the temp comm failure until it dried up.....
A judicious use of water when washing goes a long way...
Some things to to try that would prevent this....
Anytime I undo a connector for checks, mods, or maintenance... I add dielectric grease to the sealing portions on the connector.
When washing a bike I always try not to introduce water directly at electrical connections.. Certainly not pressure washers.
I often "dry" my bikes with one of the blower/driers on the market... Luckily, I bought mine before they got very expensive. Some just use a leaf blower. I focus the drier on any electrical connections that got wet..
I've yet to have this issue on my bikes after washing...
