Hi everyone, I am wondering has anybody had any success in communicating directly with the PDM in a 2015 vintage leaf.
I have removed a unit from a wrecked car. I have it set up on the bench and connected all the connections I believe I need thru the B24 connector. I have powered the unit up with out a battery load and I have measured a 5 volt signal on the battery connections. I presume this test signal out to the connector to see if teh battery is there. A short burst of data is sent out over the can bus at the same time. I have connected a test battery load to it in the 340 volt range and it does not change any of the start up conditions. Changing the inputs on the B24 connector does not initiate any new messages over the can bus. The two messages are as follows, grabbed using a DigiView D9:
FRAME TYPE DATA
This message is sent a number of times and followed by :
FRAME TYPE REMOTE
Also sent a number of times.
I am going to be setting up packet sniffing on a working leaf to try and figure out the messaging. I realize I have to pick this particular data on the EV SYSTEM CAN not the CAN Communications circuit.
My hope is to move the Battery and charging system into a 2002 Toyota RAV4 EV replacing the NIMH pack and charger with as little of the leaf system going with it as possible. I am going to attempt to spoof the RAV4 EV into thinking it still has the NIMH pack.
The leaf pack looks like it will be content to operate independently,
First step is to get both the pack and charger working independent of the VCM and the rest of the car.
Any insights in how to communicate with the charger appreciated.
Dangerous if left unattended.
