In May this year my Prius (2008 or 2013 Hatch 1.5L, running over 400k km) went into Neutral and stopped while running and has never run again since.
So, we put the car service in Toyota and the car is still there in this December.
So far Toyota did as below (copied from the statement)
Check for vehicle won’t start
Vehicle will go into neutral and park but won’t drive
Inspected for DTC’s found: P0AA6-526 – Hybrid Batter
P0171 – Fuel to Air Ratio
Carried out further diagnostic procedure
Inspected Freeze Frame Data – found insulation resistance of high voltage circuit and body is low
Tested Motor Compressor Assembly – all okay
Inspected Insulation Resistance (Inverter, Transaxle and Frame Wire) – All okay
Tested HV Battery Area – Low Resistance Found
Inspected Main Relays for sticking – found relay stuck causing open circuit
Replaced Stuck Relay
Tested Operation – Issue still present, continued diagnosis
Inspected for new DTC’s as per procedure
New DTC registered – replace battery ECU assembly supplied and fit new ECU assembly
Issue still present – requires further diagnosis
PRT Toyota G384347020 Relay System Main $191.40
PRT Toyota G384347020 Relay System Main $191.40
PRT Toyota G384147020 Relay System Main $179.78
PRT Toyota 8998147221 Computer Hybrid $779.83
Total $2507.27
Then Toyota will
"The next step in the diagnosis procedure is to carry out diagnostics on the A/C inverter and Hybrid Vehicle Transaxle Assembly. If all tests pass, then the procedure carries on to inspect Hybrid Battery ECU"
Yes, we already paid $2507- to Toyota.
In usual circumstances we will purchase a new second hand car however, when seeing the 80% hike of second hand car price after Corona and also we just purchased a new unit this year with loan and required some renovation, we are thinking to ask Toyota another go preparing to pay further.
This is our one and only car and we are using public transport since then. We do need car asap as we will move into the new unit late January and need a lot of preparation for the renovation, visiting Bunnings, Stratco etc.
What do you think?
OP, from my opinion, its nothing to do with all that toyota is telling and testing. Its as simple as a dead gear box (not worth your time and effort to fix components), $400 from wreakers and probably $800 labour from local mechanic.
If the battery systems is dead / half dead etc it will run on petrol regardless how much power battery can supply, remember, its a hybrid not an EV.
