I originally bought it to turn off the idiotic internal reverse beep. On the iPhone, the app can be set up, and there are downloadable PIDs for the Prius so you can monitor all the battery module voltages, temps, whatever you want.
It connects and reads codes much quicker than a Mini VCI cable. U codes are can bus communication errors. There are more Xhorse made expensive versions out there that have newer firmware 2.

However these communications schemes are not foolproof and occasionally the ISO protocol attempt fails.Post a Comment.
#Bleed prius brakes without techstream code
Usually the code reader would be successful in its first try at establishing contact with the 4Runner using the ISO protocol, and there would be no problem. They then try the pins and protocol of newer protocol standards. Why this doesn't happen every time a code reader is used: The code readers usually use the pins and protocol of the OBDII connector in a specific sequence, trying first to establish communication with the vehicle using the oldest protocol. More detail is included below, leveraged from my other posts. You only need the equivalent of a jumper wire to short together two pins of the OBDII connector at the right time and the right number of times between switching the 4Runner on and off. This procedure can be performed without special equipment such as a hand-held tester or OBDII reader. Without these numbers it can't get accurate information from the yaw rate and deceleration sensors in the center console near the gearshift and so it disables traction and stability control functions. Dropzone div exampleĬause: The code reader or other OBDII device has attempted to communicate with the 4Runner using the CAN protocol involving pin 14 and this has caused the 4Runner to erase the "zero point calibration" numbers in its memory. This behavior begins after the vehicle has been hooked to some sort of OBDII code reader or engine tester or data logger, etc. The "check engine" light does not come on. They come on again and stay on as soon as the 4Runner is moved. On subsequent starts the lights will come on temporarily as usual as a bulb check and then go off. I'm reluctantly starting a new one, with a more specific title including the exact name of the two trouble indicator lightsin the hope that searchers will more easily find a solution. Several posters have discussed similar problems, described in several different threads. That is, newer 4Runners may display trouble codes and reset sensor calibration values in response to the connection of different than earlier 4Runners pins together than the ones described below. The connector is located at the bottom of the dash on the driver's side and in the 4Runner it's covered by a small black cap. The OBDII interface includes several different protocols methods of digital communication and they all use the same physical connector, though with some different pins. Y not erase the codes first, then drive, and see what happens? Is the low pressure If it is, then the abs pump accumulator has some issues.Remember Me? 108x96 garage door In my view, this might be some kind of coincidence, since prior to the brake job, you've never experienced something like this. As JC suggested, it's worth checking whether replacement will be covered under a warranty extension.ĭxta Senior Member. You've got a Gen 2, where those are combined in one assembly anyway, so there's little point in trying to pin it down further. As for the historical servomotor code, I'd make a note of it, clear it, and see if it ever comes back. You'll always have the 'current' B solar sensor code if it's dusk or night or indoors when you read the codes. Verify the extended warranty campaign is available for your car I'm pretty sure it is. And it expires December So you might want to get this checked out at the dealer ASAP. I believe there's an extended warranty for this brake issue.
In my reading up I have seen others with similar problems that ended up bleeding the brakes to fix the issues, a kink in the brake lines, to a relay Toyota Prius Lexus ABS Relay that can go bad after changing the pads.Īny Ideas what direction I should go would be greatly appreciated and Many Thanks ahead of time! C1345 TOYOTA - Linear Solenoid Valve Offset Learning Undone Before I jump and think its the Hydro-Booster Pump Motor could maybe the recent front brake being replaced and rotor have something to do with these problems? Goes thru swings of working fine, then Brakes are hard to press, Sometimes Locks up on stops, VBS loud beep is recently being heard, then it goes away, but it does come back.
I am back now and the Brakes of course started having issues. The Car was being using while I was away with family issues. I know it should have been looked at then. It was done by a small repair shop where we used to live in Fla, am now in SC. Greetings, I've had my Prius since new and have had the Main Prius Battery replace in Tampa a couple of years back.
