Separate names with a comma.
I do not know why you would respond to a 12 year old thread, but for YOUR car it sounds as if you have a failing capacitor in the Combination...
The "Transmission Control system" on a Gen2 Prius is a fancy name for the ecu and motor that engages the parking pawl. This prevents the car from...
I will guess that was some type of "tuned vibration damper" that came apart because of rust. .
The idea is to see if ALL other systems on the car (besides ABS aka brake or skid control) can talk to the scantool. If so then the problem is...
Do the brake-stop lights come on when you push on the brake pedal? .
So if you use Techstream to perform a "health check" (scans all systems for codes), can you list what systems respond? There should be about 15...
Sounds neat, but ALL you have to do is "sniff out" the data that goes to and from the HVAC ecu on the AVC-lan bus (or maybe the BEAN bus). Then...
There can be several levels of reduced brake function depending on the fault. If the pump inside the actuator completely fails, then there is no...
Here's the circuit. The tests don't mention that the 100-140 ohms is through the hybrid control ecu. (I don't know if that's the actual value on a...
So, the various ecu's have a memory buffer that "records" some data as the car operates. If a fault triggers a code, then the ecu saves a...
Do not attempt to start until you have "fixed the problem". This system uses the HV battery and motor to "crank" (spin) the engine at 1000 RPM....
<shrug> I have read quite a few posts about problems with aftermarket pumps, but very few about genuine Toyota pumps. Spent around $150? for OE...
6°F is statistically insignificant. Only a slight increase (differential) in heat after driving at any reasonable speed is the result of a TINY...
Definitely time to replace. Did you check if the water pump and the adjusting pulley spun smoothly and quietly? If the bearings sound "dry"...
Most code readers that are at the parts store are not capable of communicating with all 15 (or so) systems on a Gen 2 Prius. So even if you get...
I had found Chapman's post some years back, and got the three bulbs - of course they are different - why would they use just one? Toyota #:...
Thanks for the followup. .
Yes, the HV battery ecu is inside the battery case behind the rear seat. Here it is with some of the covers removed. It's toward the left...
If I suspect that there's a head gasket problem, I use a pressure tester on the radiator (to 15psi) and leave it pressurized overnight. The next...
You can use search either in the forum or google. (If you're keeping your Prius, you might consider hanging onto DrPrius just to keep tabs on the...
