Prius 1.8 ABS, TRACTION, Hand brake light on

[saad1036478713]

Asallam O Alaikum Pakwheelers, recently my prius 2013 ABS, Traction and Hand brake Lights turned on and I felt a noticeable difference in braking of car it was like brakes have gone loose as I have to push harder.
Previously when applying brakes it was giving some swish sound and when brakes were slightly applied it was jerking and now I think ABS has switched off and also the regenerative charging feature.
Need help regarding what could be wrong and from where to get it fixed in Karachi car has done almost 150 K kms

It is a common fault in Prius.
Prius ABS has certain life.afterwards its need to be replaced. Dont waste money on further findings.
Just scan and diagnose the ABS unit and replaced it. Approx cost around 80k to 100k,

First get the vehicle scanned via OBD device, to check for any / all fault codes. Then take remedial actions accordingly.

Finding a good ABS unit is also a tiresome job. We got it replaced in our Prius Alpha and it has not gone well. Lights keep coming back.

The Diagnostic Trouble Code (DTC) is stored if a brake fluid, internal or other leak is detected due to improper sealing in the actuator. Internal leakage is suspected if the pump motor operates frequently without breaking.

Solution?

yes - thats the textbook line.

real issue is finding a "new" brake EH unit for it - expect close to 3K USD for a new one landed in Pakistan, scrapped items are junked and are a gamble - usually results in paying the mechanic 3 to 6 times his labour cost.

I agree, my friend faced the same problem last year and sourced 2nd hand parts.
But it turned out to be a temporary fix. After sometime all the lights lit up.
When the ABS & TC light lit up he faced a considerable decrease in brake performance.

Tell your freind to loosen his wallet and buy a new unit,

Brakes are nothing to joke with
