Separate names with a comma.
That is the "main" 12V cable that connects the battery to the car. So when you want to power up the car all 12V for everything has to go through...
You need a more capable scantool to check the 15-16 systems on a Gen2 Prius. Here is a thread that reviews several options. The synopsis is post...
I hope you were able to figure out what was going on. FYI, the more capable apps (such as Autel and ThinkDiag) will only work with their own...
Not a dumb question, but no, you can't have "auto" function on the other 3 windows. The driver's window uses special hardware that's built into...
Does the dome light work when you open the driver's door? (and do you get the red "door open" icon on the dash?) .
Much depends on how the car is used. As you noted, regular - steady driving allows the car to keep the HV battery in the 5-8 bar range. There's...
I use the term "normal high pressure valves" to describe the parts of the brake system that contain high pressure fluid when you are not stepping...
Negative block voltage readings on Dr Prius point to open circuit(s) somewhere in the voltage sense wiring. Might be at the module stud terminals....
Use your scantool to watch ABS data. The ecu uses the ACCumulator pressure sensor to control when to turn the pump on or off. How much does that...
That doesn't happen in places that have salt. Corrosion will lock the bearing in the knuckle. .
IDK what tooling you have. When I see a car like this I first visually inspect the gas cap, then use a capable scantool to actuate all the...
This isn't high current flow across any two connector pins (at least not initially). It's the high voltage potential that makes the materials...
T1 Terry "As a 40 yr plus mechanic, I have seen some really strange things, like wiring harnesses with an oil leak," 35 years here. As far as...
What codes do you have and what testing have you performed? That part # is for the "trap canister with outlet valve" - the valve is actually the...
It's possible. There also are several versions of the OBD2 cable out there with various reports of erratic functionality. Some "work just fine",...
Here's a question. Wouldn't "just" bypassing the coolant loop of the heat exchanger cause some performance problems? Part of the system is a...
IF that's what happened, then rust formed on the "swept" surface of the drum. It can bond to the brake shoe friction material. This usually...
I would expect the hybrid control ecu to throw a code, (maybe disable the DC-DC converter?). .
You have failure of the voltage sensing wiring or the orange connector on the battery ecu. You still might have battery problems besides, but...
Look at ECM data for engine operation. What is short term and long term fuel trim numbers at: hot idle, fast idle, moderate acceleration, and at...
