Lasterr = precharge
Status = udc below udcsw
Opmode = shows precharge for 5sec and then back
to off.

Have videos but unable to upload at the moment as website does not except. MP4 format.

Re: Lexus 300h trans not spinning

I can't see an IVT shunt. The Zombieverter will look for an hv signal when precharge is energised. If it does not see HV on the canbus from the shunt the inverter will not be turned on by the Zombieverter. Hope that helps Was not aware that the shunt was needed when doing a basic bench test. Will t...

Udcsw set to 0v which has deleted the 5 sec time out and still no inverter whine .

Re: Lexus 300h trans not spinning

udc is reporting 0v? From the wiki: "Apply the Start 12V signal for a short time. The pre-charge relay should turn on, and the voltage available at the inverter and the U1 input of the ISA shunt should quickly rise. If the udc reading goes above udcsw within 5 seconds then the main contactor(s...

Maybe the drawing just isn't very clear, relays should really have the coil and contacts/switch shown.

Hi guys, new to the forum. Have recently purchased the zombieverter vcu from Damien and had it assembled as per video but still have to fit IC 10 as not supplied in the kit. After connecting the resolver cables and doing a basic power check using 12v volt battery the micro controller IC 8 started gi...
