what is a plenum?
Running the tmp sensor test I realized that the previous
errors were cause by the connector for CN100 plug NOT be seated correctly.
I ran Leaf Spy and will send them to you by the morning.

Top and bottom plenums are the chambers above and below the heatsink plate in the PDM. You removed the top cover to expose the control electronics in the top chamber/plenum. There is also a bottom cover and bottom chamber that has the high power electronics, pfc boost section, PWM switching transistors, boost transformer(s), and diode rectifier stage with HV DC Output filter section before sending it to the Main Battery Pack.

Pretty good. I burst out laughing near the end, with:

Brrruuuuuuuuuuutt!!

"Stupid combustion engines!"

The design does seem to be the result of a lot of "ICE thinking", all those intricate plastic and copper parts. And M6 bolts! Sandy Munroe would not approve. I think they could use a bit of Elon's "The best part is no part" thinking.

I didn't see any motor controller IGBTs or snubber capacitors. Are they down another level again?

I can answer my own question; yes, it's the next thing down, with the motor and final reduction gear under that.



And now back to the original topic .

Built by Panasonic.

There is provision for a jack screw to remove the cover on the front side of the PDM between the 2 center bolts that i think nobody has found before.

Also i think i saw snubber capacitors in the bottom plenum on the rectifier board, the blue M&M type caps.

Looks like a good setup to test for missing temp sensors.

Don't forget about the interlock on the PDM lid.

Description INFOID:0000000009329364
The connection detecting circuit is used to detect the connection status of the PDM (Power Delivery Module)
cover and the bus bar cover of PDM (Power Delivery Module).
The connection detecting circuit consists of two circuits (i.e. power supply circuit and signal input circuit).
When the PDM (Power Delivery Module) cover and the bus bar cover are installed normally, their protrusions
press the internal switch of PDM (Power Delivery Module). Accordingly, the connection detecting circuit is
energized and a voltage signal is input.

I removed the QC temp sensor simulation resistors

B2830-96 09 Charger Q/CHG voltage sensor VC-66
B2830 QUICK CHARGE VOLTAGE SENSOR
The quick charge voltage sensor is integrated inside the PDM (Power Delivery Module), and detects the volt-
age at the + side and − side of the high voltage circuit on the upstream side of the quick charge relay (quick
charge port side). The PDM (Power Delivery Module) monitors the status of the quick charge relay based on
this signal.

Were these while trying to charge, or to start, or just putting the car in ACC mode?

Seems like the PDM is smart enough to know when it is missing the Chademo harness and wiring?

Ign button, Break Depressed, Neutral. Would not go into drive.

1 QC temp sensor simulation resistors active. (did not produce/remove a DTC code)
2 PDM cover closed and bolted on front side ( how is the PDM interlock switch depressed?) (interlock gone)
3 How does one satisfy the QC voltage sensor?

It seems odd that it would be trying to measure this considering that you weren't charging Regular or DCQC.

The measurement circuit is on this board. There is a big voltage divider network of all those resistors, but i can't find a datasheet for the photocouplers nor see how to trace out the circuit from just a picture. Any idea about the polarity? i would guess that HVDC + is on the left, and - is on the right.

hvdc - is duplicated on the left solder joints. HVDC +
no connection between the two.
empty holes at TP717 connect to nothing

 

[nlspace]

Looks like my guesses on the Chademo board were incorrect, but it's puzzling that you can't find any continuity or connections on that board.

There may be damage on the backside or internally of that board. Might explain the HV inverter DTC faults. the double solder joints along the upper edge should not have continuity.
