no codes, yet I have brake, ABS, VSC,((!)),TPM

There are codes for sure, you'll need to get a Prius capable code reader. The tire sensors need to be replaced to turn off that light.

 

Is Torque what you're trying to read codes with now?

It shouldn't really need special plugins ... if it asks for codes, the car's computers will reply with codes, and Torque could show you those even if it doesn't know what they mean. Looking them up is what we've got repair manuals for.

For the ABS/VSC/((!)) lights anyway, you don't need a scan tool of any kind. You can use a short wire between the Tc and CG terminals at the diagnostic port, and count the blinks on those lights into two-digit blink codes. (Search here with those terms for more details.)

I'm not sure the TPMS participates in that, but if you notice that light blinking patterns too, then go ahead and write those down.

 

There are PIDs that can be installed so that Torque can recognize various vehicles, including a gen2.

 

Vehicle-specific PIDs (Parameter IDs) are useful if you want Torque to be able to read Prius-specific parameters from the car (like battery state of charge, inverter temperatures, pump speeds, and so on).

That would be in addition to reading DTCs (diagnostic trouble codes), which I do not think Torque should require any special measures to be able to read. DTCs are just a standardized way for car ECUs to report issues.

A scan tool might not know what all the DTCs being reported mean, but it can still show them.

 

It sounds like you may have a failing combination meter, best to sort that out sooner rather than later.

You can DIY fix for under 10usd, or buy one with your mileage already programmed and has a lifetime warranty for 150 or less.

 

There are 5 INF codes (which you can find in the freeze frame data) that will help narrow down the trouble area. The INF code possibilities are; 581, 582, 583, 584, and 585. It would help if you could find that and post it here.

The trouble areas are:

• Fluid leakage
• Brake actuator assembly
• Disc rotor

I hope that helps.

 

Looks like potential leakage or bad actuator.

Here is the workup for DTC C1344 (and C1341 C1342 C1343) : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/Repair%20Manual/04pruisr/05/21avn/cic13416.pdf

The above is from an older 2004 manual, a later version may have a different workup for your DTC / INF.

 

The hydraulic pressure control on the rear left wheel has deteriorated.

The two possible trouble areas are:

• Fluid leakage
• Brake actuator

The link posted by SFO will help you diagnose it to one or the other.

References to the handheld tester can be replaced with the equivalent Techstream procedure.
