Possible toyota prius have same battery cell. Try ebay there are many refurb sets. Good luck.

Hi can't find anything on that code, you can try check live data on hv control system and hv battery and see if you have anything abnormal . The pump is on passenger side under the bumper attached to chassis leg, if you take off bottom bumper panel you will see it and radiator, alphard got only one radiator but bottom 1/4 of that is dedicated to cool inverter is like 2 in 1. Pump on the picture is from Prius but Alphard is similar just side hose attachment are moved 180°.

Hi if you know the inverter are 100% good, that's fine. Not sure what 63 sub code means, usually is tree numbers (can you post freeze frame picture) but will be good same time check the inverter pump and radiator if is not chocked, my pump was running but radiator was blocked and that caused the problem with inverter, simply overheating and coked electronics. Good luck and keep posting.

Hi Two months ago I didn't know much about hybrids but after hours of reaserch, I would say I can do it /fix them or diagnose. Megazip that's the website where I ordered the parts, two other pictures are from website where you can find parts number. The high voltage system are easy to workout, first you have to disconnected the 12v battery (negative first) take off safety plug (on the back of the passenger seat orange plug) the best put it in the pocket. Then you wait least 30min. To give the time for decharge the capacitors. When you open the inverter/converter the best double check if the power are disconnected (using multimeter and measure DC voltage) should be 0. But before you do anything, diagnose the car with teachstream or other compatible device. Cheers

HiRight there I have a we update, I manage to get teachstream from ebay and diagnose the car again, find on freeze frame : P3125 inverter mulfunction And subcode 472 One of the guys had same problem with same codes, and suggested to replace current sensor for rear motor what I did (order from Japan) and problem solved. Car drive like a dream again.

Hi all I had consultation with few hybrid technicians and possibly one or few hybrid batteries are bad and they have to be checked, replace if needed and all 28 hybrid batteries have to be recharged and balanced. They said it is common procedure for older hybrid generations no matter what mileage they have. I will take mine apart probably naxt weekend. Cheers

Hi all, checked tyre pressure but no difference, checked abs sensors (same values for all wheels). Looks like warning lights come up after start to acceration or deceleration, I suspect acceleration pedal but values change on live data when press and depress the pedal, also suspect angle sensor because values stay constant 1150 on live data no change when move steering wheel. Managed to read fault codes and live data by autel maxidiag 808 Pro, - p3125 inverter mulfunction - c1259 HV system regenerative mulfunction - c1310 HV system mulfunction Last two disappear after swith off and switch on the ignition. No codes for acceleration pedal or angle sensor. Car starts and drive with warning lights but with limitation to 60km/h. Any one know how to test the inverter? Not the one between the seats, the one under the bonnet on right side.

Hi got similar problem, same warning lights come on +4wd. When get the car battery was completely dead, charged the battery and stationary all looks like should- car starts no warning lights hybrid system works with all the charging arrows on the screen. Just when the car reach about 10mph ,after we gearbox kick all warning lights appear. After hours spend on research got some hints: looks like toyota are sensitive for low battery voltage and need reset of few components: 1 . power windows - done 2 .check tyres pressure 35psi front and rear - done 3 .angle sensor - will try in next few days Manage to check fault codes by AUTEL MAXI DIAG MD808 pro my codes: P3125 INVERTER MALFUNCTION C1259 HV SYSTEM REGENERATIVE MALFUNCTION C1310 HV SYSTEM MALFUNCTION C1253 HYDRO-BOOSTER PUMP MOTOR RELAY - that one possibly create the problem because VSC FAULT AUTOMATICALY DISABLE HV SYSTEM, but first will try reset angle sensor (angle sensor is crucial component of VSC system and on live checks when engine running angle sensor value not react on steering wheel movement) alphard hybrid 2.4 2004 with around 75000miles on the clock. Any suggestions welcome.

Look like no luck with resolving the issue, my 2004 hybrid start showing same wirning lights: 4wd,vsd,orange(!), red car with (!), management light. Car starts and drive, the theory with tyres pressure make sens and I will check them. What make me think, when car is stationary or slowly move there is only management light and red car with!(!) are on, just when get 10-15km/h rest of the worning lights appear. Will check tyre pressure tomorrow and share results. Cheers
