Doesnt run , after been parked for a month

Afacapel · August 8

I just put a new Battery how they recommend , and is true all the issue about replace Battery pack , vcs, ebc gone , also I put the Battery sensor for temperature , reset the codes , and now just appear one code but not related with the Battery . I just post a video , so you can see what the car does , but basically goes in ready for 0.5 second and disappear , looks like is trying but doesn’t run . After checking with the diagnosis I found out , the hybrid Battery is 0% so I’m thinking probably the issue is coming from here . I don’t know if someone can point me to the right direction

I'm no expert on the traction Battery but I reckon that is at fault in some way.

First of all there is too much variation between Battery blocks with the lowest being 10.28V and the highest 14.83V.

I think the traction Battery may need charging, which means taking it (flat-bed recovery truck maybe?) to either your local Lexus dealer or an independent hybrid specialist for them to sort out.

there is anyway to try to charge the Battery without going to the dealer ? or bypass the Battery and run the car ? thanks

No, only the dealer or specialist can recharge the traction Battery. The car cannot be run at all if the hybrid system fails to start, there is no starter motor and no alternator.

Peter has beaten me to it because, being retired, there's only one 6:25 in my day and it isn't that one :yahoo:

Unfortunately no, there's no way other than getting it to a dealer or other hybrid specialist. The traction Battery stands at somewhere in the region of 300V so this isn't something you can DIY or even get the AA/RAC/Green Flag out to.

It's 288v nominal (6 cells x 20 modules x 1.2v).

Might want to paint the complete picture - something about the previous owner having experienced the same or very similar thing - and why you were told that it'd be a good idea to change the 12v. Also the fact that the car'd been parked for 2 weeks. It's a different board 😉

It's extremely weird for such a car to fail like this out of a sudden. Also weird that it isn't throwing a Battery code given the voltage difference between the blocks (1 block = 2 modules = 12*1.2v = 14.4v nominal, if >1.2v delta is detected = p0a80 is set).
