Hybrid Warning and cutting out


Recommended Posts

Hi

I have a 2004 Alphard E4 hybrid import and it was fine for a few months, have had trips away and all fine but after a trip to Devon the Hybrid Warning (red car with an exclamation) light came on for a but then went off again.

A couple of months later it came on again and the engine cut out, after another couple of months (now) the light comes on, engine cuts out randomly, restarts, runs with light on, light goes out after a couple of days, runs for a few days without warning light, light comes back on, cuts out randomly.......repeat......repeat

 

I took it to my local repair guy and his reader didn't read any fault codes.

 

I took it to a Toyota main dealer who also didn't read any fault codes, apparently because it's an import. They did say it might be the 12v battery though, so I changed it, but no luck, still cutting out.

 

Any ideas how to get this diagnosed, or any ideas what it might be?

 

Thanks in advance

Hi,

this is my first post- I have an Alphard Hybrid E4 2005 purchased from Dave at Vineplace Motors in October last- can thoroughly recommend Dave if anyone is looking for a vehicle. Vehicle was fine until just at New Year and the 12v battery kept going dead and eventually wouldn't start from the booster pack (Noco GB50- would recommend this) and until that point was doing odd things. Dave had fitted a new battery at purchase but was a standard Alphard battery in error- he kindly sourced a new battery FOC as the system has to have a special stop-start type- the replacement was Panasonic S55D23R (advertised as for a Toyota RAV 4 Hybrid) at £199.99 but the supplier said this was the manufacturers genuine part having been supplied the vin no.- sourced from e-hybrid.com who apparently specialise in hybrid spares. Fitted the new battery and everything has been fine since then so the 12v battery appears to be critical- there may well be other suitable batteries out there but this is my experience.

Vehicle drives beautifully and I am getting about 35mpg driving carefully and using the hybrid system so I use it more often than I expected.

Hope this helps.

Hi PaulE

 

Thanks for the info. The Toyota garage, did say it needs to be a genuine battery and I was hoping that another one the same as the old one would be ok as it had been fine for months. I need to decide whether to spend another £200 and find it still misbehaves!

 

I have also noticed that the VSC light comes on when it cuts out.

 

It all seems to be guesswork right now :(

When I had my 12v battery problem the dash showed the headlight symbol on all the time and the HU was dimmed although the headlight was off. Changing the battery fixed the issue.

Quick update.....

 

I managed to get this code using OBD Car Doctor. There's no subcode though.

 

Searches show that it's possibly something to do with the Inverter cooling system or a faulty pump. The car was making a squealing sound when starting up and steadily got worse, so that could indicate a failing pump.

 

Has anyone here changed an Inverter cooling pump?
