Oled screen dead on first startup Leaf 2017 80kw 30 kwh Type2 (euro) charge port
-
The little screen does not turn on. Voltage is 3,3V and the contactors on the precharge unit opens up to the charger. The charger delivers 14V to the battery and the water pump starts after a few seconds.
Nothing more happens. When I try to turn off with the ignition key The contactors dont let go. I have to Use the HV breaker and then disconnect the 12V battery. Then contactors open.
Om the PDM I connected pin 30 to white wire and 29 to green.
Using Leafspy and I get a ton of fault codes. Battery looks OK at 90% SOC.
I went thru all wires multiple times.. Any suggestions?

This really feels like something is wrong with the Resolve ev box? The little oled screen does not wake up. If all CAN wires are connected nothing clicks. If if I disconnect the PDM CAN the HV relays closes and opens with the ignition key. With The Inverter CAN disconnected Relays click ON but stays on even if I turn off ignition power. If I disconnect both Inverter and PDM CAN and only BMS CAN is connected to the Resolve box Relays turn on and off with ignition power but in all cases the oled stays dead. When the PDM gets HV it charges the 12V battery. The water pump also starts as intended.

Wheels are now turning! HV relays turning on and off with the ignition key.
I have an American J1772 charge port..NOT a Euro Type2. So the white wire is to be connected to the white.
Oled screen still dead thou. So I guess I need a replacement.
Still in a bit of euforia 🥰 -
Hi @Emanuel !
If the wheels are turning now I believe you unfortunately got a bad display (we always test them before shipment but we have had a batch of bad OLEDs recently) Could you please reach out to us via email and I'll send you an new one. info@resolve-ev.com -
Thanks! all is good now. The new oled screen works fine, and the little box it now came with, makes it a bit easier to mount.

The first OLED I got was just a screen on a circuit board. The working one had a small housing around it. see picture

This is a link with instructions to make a cable/connector directly to the battery pack. Then you can check if the HV wiring is OK before connecting it to the Resolve-box. Here you can also find fault codes and lots of useful stuff.
