Hello and thanks for posting welcome to the site.

A couple of things to check first, make sure there are 12 volts to the fuse box under the hood, open the red cover with the plus sign, you should have slightly over 12 volts, if this checks out good check the re check the orange service plug on the hybrid battery, make sure it is in the locked on position, by that I mean when installing the plug push it on the terminals the flip the lever in and then push it down to lock it and complete the circuit. If the last step is not done nothing will work, let me know if this helps so far and if you have any other questions.

Thanks..

What do I do next
Toyota Mechanic: Ted Ritter, Toyota Master Tech replied 1 year ago

With the HV battery at one bar it should still start the engine, it's safety feature that is built in to not let the battery go below to where it won't start. To continue to be able to help I would need to have you check for diagnostic codes if you have a code reader that can access the hybrid system.

As I look over your pictures, it appears the service plug is not installed properly. The plug goes in, the lever rotates, then, you must SLIDE it in to properly seat it and make connection.

Which picture? Not sure what you are calling service plugYoutube showed me. I will try and lock in now. ThanksDid lock it in place and no change. Did not realize there was a two pin safety connectionStill getting the car and exclamation icon and red triangle. What is puzzling is the ICE doesn't try to start ancharge HV battery. I think its a simple fixbut hard to find
Toyota Mechanic: Boxer54, Toyota Technician replied 1 year ago

Did you try to clear the codes after correcting the service plug installation? Your code reader may not access the hybrid ecu. You may need to disconnect the 12 volt battery for 30 minutes or so.
