Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Do you have a code reader to see if there are any codes set in the engine computer?
Does the light in the start button illuminate? If you have the key in the slot and push the power button twice does anything come on on the display?
What about the LED in the start button does it ever turns green does it turn red or orange or does it flash when you try and get the vehicle to ready on? Did you have the jumper cables to the battery in the back or at the terminal in the fuse block on the hood? Do the rest of the electrical components work for example the Windows wipers lights and so on?
Have you had the battery out of the vehicle and had it tested at a nearby parts store? At any time did the jumper cables get hooked up backwards even for a split second?
The black or negative battery cable should be on the negative post which goes to the body on the battery the positive or red cable goes to the positive terminal on the battery which has the large plastic cover over the terminal. If you are under the hood the red jumper cable goes to the terminal inside the fuse box under the red lid. The negative or black cable would go to the case of the converter/inverter or any good clean metal surface under the hood.
You're welcome. Please do not forget to rate my assistance at three or higher if you have not done so already. You are probably going to find that the battery is going to have to be replaced. Have it tested and or replaced.
I'm not sure why that is the case see if anything comes up after I send this reply to you. Thanks for getting back to me.
