Honda Civic Hybrid 2006 VSA and IMA light ON?

I have Honda Civic Hybrid 2006. Last week, I have done wheel alignment and after driving 1/2 mile, IMA & VSA light turn on. I changed the gear into parking (Automatic) and gear shift got locked in Parking mode. I left the car for 1 hour and after that VSA light went off and gear shift lock released. I drove the car to my home and next day IMA light turn off as well. Same thing happened again after 3 days. At the moment, there's no IMA or VSA light at the moment, But I don't want to be stuck in the middle of the road another day.

Diagnostics Codes:
P060A
P16D6
P16D5

Any help is highly appreciated. Thanks

Added (1). I have gone through Honda Full Diagnostics Test and got same above code and solution suggested is to put new ECU, and there's no guarantee that problem is going to be fixed or not.

Now twist here is as per my findings, the problem is only triggers at specific temperature, like if I leave the car under sun for few hours and temperature touches some where round 23-24 C. After that when I start driving for 2-3 miles, it come up. And if I leave the car and wait for it cool down, it goes away.

They are invalid codes. If the IMA light is on, it's a good possibility that the IMA battery pack need to be replaced. How many miles on the car? The warranty is 8/80K for the IMA pack. There may be an extended warranty on the IMA pack to 10/150K. Call Honda or your dealer for more information.

This video will help you to understand how the IMA system works on the Civic:

The VSA light come on is probably related to the IMA problem. So call your sealer and let them look into the IMA system. Who knows? The IMA system is still under warranty.

Edit: This is very informative, it's mentioned about the VSA also:
