Triangle of Death — My notorious Toyota Prius
My car is a first-generation Prius; as it is a millennium product, which made the price inexpensive. Although it is well-known for its traction battery problem (the battery drives the vehicle), I still brought it after checking the battery was in good condition.
Like all electronics, appliances can die without any warning. The engine warning light and the red triangle first appeared after 9 months after I brought it. The car had got a pass in the Toyota hybrid battery test 3 months before the warning alarm. There were 2 options, 1)replace the car or 2)fix it. Obviously, I chose the latter.
I am not a car mechanic or engineer, I learned and tried and succeed. Here is the walkthrough, I listed out some product links so you can find them, some of the links are affiliate link which will generate a commission but no cost to you.
WARNING! If you are not familiar with batteries, leave it to professionals! I studied for a long period before hands on. And insured I wore the protection during the repair.
Tools I recommended:
ODBII
Haynes for most of the model (2001–2012)
DEWALT® Small Mechanics Set, 50 Piece
Charger and Discharger
