Prius 2008 C1241, C1378,B1650, B1660, Is it worth repairing?

47.1 was rated mileage for that cat 45 not to shabby at 05 w original HV .few years past due. The ABS VSC trac light kind of interest me more as well as the supplemental restraint light or code could be the clock spring or tape thing stuck on the steering wheel do all the buttons on the steering wheel work? Volume up and down all that stuff. Is there a light on for the airbag that does not go off do you hear the whirring of the ABS pump 30 seconds to a minute after you shut off the car Go back and open the door after that stops and it starts again things like this. I personally would definitely probably be getting my HD battery but check the little bit more what about the 12 volt that needs to be good.

 

"Worth" is a word that means different things to everyone. One person might only have 1 car and depend on it for generating income. Someone else might might have 2-3 cars and is "looking for a reason" to trade one in on a new car.

That said, I am not sure you have all the information needed to make a decision. You have 2 ABS codes, and 2 airbag codes. I would not expect any to account for a "stutter" while driving with a master warning. Unless your scantool specifically says that it scanned both the hybrid control - high voltage battery ecu's and neither had codes, then it's not fully capable. You can have codes in systems that your scanner can't report.

Read the sticky thread at the top of this forum to learn about different OBD scantool apps and devices. Post 37 is a summary.

You don't mention the airbag light being on, so look at the ABS faults. (I assume that you have ABS or other brake warning lights on?) One code indicates that voltage at the ecu is less than it should be- possible wiring, relay, or even 12V battery problems. The other code indicates a fault for the ABS backup power supply (the black box near the 12V battery or its wiring).

What were those OBD2 codes?

How often do you change/check the oil in the engine?

When was the last time the inverter coolant pump was replaced? (total miles since)

 

Now would be a good time to rescan with a hybrid compatible scanner. How is the 12v battery, and when was it last replaced?

Here is the workup for DTC C1241 : 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/cic12414.pdf

Here is the workup for C1378 with INFs (subcodes / detailed codes) 112/113 : 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/cic13784.pdf

Notice how the above workup has two different INFs for DTC C1378, having a compatible device that can tell you the associated INF/subcode/detailed code may help with diagnosing the problem, and potentially save time and money. Many here like to use a mini-vci cable (or better) with techstream (dealership technician software), others may get by with using a quality bluetooth device (mentioned above), and the appropriate app.

Here is the workup for DTC B1650 : https://priuschat.com/attachments/b1650-pdf.13728/

Not sure if this thread is helpful for DTC B1650 : https://priuschat.com/threads/srs-problem.59673

DTC B1660 is an Airbag issue on the passenger side. Check some of the online videos on how to reset it.

When did you last replace the spark plugs?

Could be a leaking valve cover gasket, and it may need replacement.

 

Good Ideas and write up. I would also plan if you are able to start putting away a "car payment" every month to give you a nice down payment on your next car in 2 years.

 

What OBD2 codes do you have that point towards a dead HV battery?

Best to buy a new HV battery from the dealer (1650+), or try one of the NEW aftermarket options, either NiMH or Lithium. @PriusCamper had talked about being in the area for a lithium battery installation meetup, though not sure when that would happen.

Don't buy an old "reconditioned" battery, though you might be able to find a decent used pack out of a recent wreck/salvage.

Did they actually steal the OEM cat, or is it still intact?

 

Odd, you should have a P0420 stored. What OBD2 device or app are you using?

 

C1259 (blink code 58 on the ((!)) ECB light) and C1310 (blink code 51 on the skiddy-car VSC light) are two secondary codes and neither code means any problem with the brake system at all: they both tell you about some problem elsewhere in the car (in the hybrid powertrain control) that the brake system just needs to know about (because those systems cooperate to do regeneration). So these codes just mean you need to get the codes that really matter, from the ECUs controlling the hybrid system. (Sadly, that means you do need to arrange access to a scan tool because those ECUs don't do blink codes.)

These symptoms suggest hybrid battery problems. The code reader used is obviously inadequate, as it is missing codes. You could read this thread that reviews a few different code readers and outlines the capabilities of each.
