Red error alert ID901&ID920

[noguchi]

こんにちは。
誰かに教えてもらいたいです。PEMコネクタを交換した後、エラーアラートが表示され、実行できなくなり、充電されなくなりました。
温度表示はありません。赤いID901とID920のエラー表示があります。

のぐち。

過電流エラーのようなのでPEMのどこかが短絡（ショート）した可能性があるように思えます。（充電ケーブルがショートしてなければ）
USBメモリでログを取得し、Gruber Motorへログを添付しメール問い合わせすればどの辺があやしいのか、ロードスターエンジニアの回答が得られるかもしれません。
（おそらく横浜サービスでは回答が難しいレベルのように思えるので）
私も以前別件で問い合わせした事がありますが、平日であれば速やかに回答得られるかと思います。

It sounds like an overcurrent error, so it seems possible that something in the PEM has shorted out.
If you get the logs on a USB stick and email Gruber Motor, you may be able to get an answer from a Roadster engineer as to what is wrong with the system.
Probably because it seems to be at a level that is difficult for Yokohama Service to answer.
I have also inquired about another issue before, and I think you will get a quick response on a weekday.

I ran the initial message through translate and got this:

Hello.
I would like someone to tell me. After replacing the PEM connector, an error alert appears, it can no longer run, and it no longer charges.
There is no temperature indication. There is a red ID901 and ID920 error indication.



901 is DMC HW: PhaseA OverCurrent Fault and 920 is DMC HW: Line OverCurrent fault.

Given that you just replaced the PEM connector, I'd guess that you didn't do it properly and things are connected the way that they're supposed to be. But Carl Medlock could tell you for sure.

I meant to say: "things are not connected the way they're supposed to be."

RE: your temperatures, what's shown is probably fine if the car is just sitting and not being driven but if you could turn on debug mode from the "hidden" service screen, we would see the actual temps.

More importantly however, the car is down to ~50% SOC so you may want to consider pulling the ESS service disconnect to preserve what's left until you can get the connector addressed.

Thank you for your comment.
Check the wiring of the PEM connector again.
When it can't be improved, switch the battery to save mode, hibernate, and wait for Tesla SC's home repair mobile service.

Thank you
Noguchi.

Not rechargeable, 100V, 200V, red light
Unable to drive, error display ID901, ID1144, meter red Fault
disappointing…

The PEM connector was remade and installed, and the other three connectors were also cleaned and contacted with grease. Battery storage mode, charger 100V connection, charging port green light. I checked the operation of the PEM fan and the motor fan, connected the 12V battery, and the two fans worked. No burnt connector. I applied contact grease to the connector and connected it. The error alert display remains unchanged. Noguchi.

Check the micro switch for the small PEM cover.

Hello.
Does anyone have a wiring diagram of PEM?

Check the micro switch for the small PEM cover.

Thank you for your comment.
I checked the microswitch. No problem.

Hello, please tell me.



I installed it yesterday, I still get a PEM fan motor error display ... I can't charge it.



PEM fan immobility when 100V and 200V charging, unchargeable error, new fan replacement, DC12V energized directly from the fan connector, fan turns.



PEM connector replaced, motor fan side and PEM base side.



Error message, unchargeable, PEM fan error display.



I'm sorry to trouble you. Noguchi

Not the problem with charging, but while you're under the car you should check the other end of the PEM Fan cable, where it connects to the fan assembly. The two sides (PEM and Motor) connect in parallel on the motor side of the pair of F-connections. On mine, the electrical connections weren't very tight, and that causes the currents to not be equally shared between the two feeds from the PEM. Over time that caused some of the contacts in the PEM-end of the cable to get overloaded and burn. A gentle squeeze of some needle nose pliers can tighten up the female side of the connections. See Think I need a new PEM Fan... Anything else to check? and a couple of posts later in the thread.

Two new fan motors have been replaced, and the PEM and motor cables will be replaced with new ones.
Ichecked, but there is no burn on the connector on the fan motor side

Ok, good to know. So, you still have the two-motors one-fan-each arrangement? Mine is one motor with two blowers, so my thread's solution of wiring the two sides together does not apply to your case.

When I did my own cleaning out of the PEM and motor debris last year, I had a 901 error (I think), but it cleared simply by turning the key to the "on" position. That's what it meant by "restart when safe", apparently. I presume you're well past that stage in troubleshooting.
