Hybrid Warning and cutting out

[Marty2112]

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 bit 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 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

Hi There did you manage to sort the issue - ours has just started doing the same...

Make sure the Battery pack vents are free and clear IIRC, on the Alphard one is located at floor level in front/behind one of the seats filters get clogged and ducting needs cleaning

Is it an E-four ? contactor and fan location

thanks Flash22, I will take a look.  Just phone the company I got it from who suggested it might be a faulty fuel cell, would that make sense to you?

i would check the fans first, a Battery recon is not cheap

 

edit. Disconnect the 12v Battery and pull the service plug before working on the car

do you have pics on how to do it? looking at the fixmycar blog it looks quite involved...

Disconnect the 12v Battery and remove the passenger seat
