Separate names with a comma.
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...
When you disconnect the 12V battery, you reset the high voltage ecu (ie, give it "amnesia"). The default value for SOC is 60%, and it takes some...
