Toyota CHR u0100 Error code

Hey, sometimes the u0100 code appears in the car, and after a while, it just disappears on its own.

Sir, could you please look into the main 12-volt battery? It might be reaching the end of its life. Also, try finding a workshop that can do a scan. The code is showing a communication error, which might be due to a loose connector between the ECU harness, HYBRID battery connectors, o r HYBRID drive unit.

Given its an old JDM car, theres a good chance the primary battery needs replacing, just a heads up.
