Pcs 2 fail or not

[njwilson]

I recently had my high voltage battery replaced after a month of waiting to get it done and 3 days after I got home with the truck I get a message from Tesla. The message was that a diagnostic test was done on my cybertruck and the pcs2 needs to be replaced however none are available so until it can be replaced I will get free supercharging. I was charged for my charging session so I called the Tesla service center who replaced my battery. They stated that the pcs2 is fine and won’t reimburse me for the charge. I actually have a message from Tesla stating it’s bad and needs replacement. Any advice?

I would raise the issue to management, especially if you got the text saying you'd get free supercharging. You can send an email to [email protected] and attach the screenshot of the message, plus the invoice for the charging session.

Thanks for the info

I am in the exact same boat with my SC right now. I was told last week that PCS failure was confirmed and I would have free supercharging. After charging today, my credit card was charged for the session. I messaged the SC, and they responded that their remote diagnosis showed no failure, and that’s why I was not provided free supercharging. Now they want me to bring my Tesla charging cable with the truck back to their SC for testing. I have all the communications with them documented and screenshots too. Am I getting the runaround?

Service Mode is your friend.

I had the same fail on the PC2 - I was comped for the supercharger and went on a 4000 mile trip with free charging . They changed the PC2 and I have been fine since.

How would I use service mode in this scenario?

Service Mode will display all the fault codes generated by the CT, including transient and spurious faults. Any remote diagnostics done by Tesla are going to be looking at those.

You've gotten conflicting text messages from Tesla personnel. One of them is wrong. Service Mode will tell you which one.

Thanks! The PCS2_A051 failure code is not in dispute, my truck received it and SC personnel acknowledged it. My dispute is that as of now, they are telling me this failure code, “can currently be ignored.” Now they want me to bring in the truck and my Tesla universal charging cable today for testing, because that might be the issue for 24A max charging I’m getting at home. Seems strange and I’m wondering why they are backtracking, and how hard I should push to be put on the PCS list and free supercharging as they originally promised.

Not sure if anyone responds to this email, I emailed them like 2 weeks ago with no response for a different issue. Regional and the local service manager won’t reply to my response.

If it were me, I would just go with the flow.... bring your mobile charger in for them to look at. At the end of the day, the SC is going to have to demonstrate that you can charge at 32 amps. If your PCS2 is indeed failing, then they're not going to be able to do that.

A word of advice... it's helpful when discussing faults/failures to be ultra precise. Especially when dealing with Service Center personnel, but also here or anywhere else. You didn't, for instance, mention in your OP that you were limited to 24 amps when charging. That's a pretty significant identifier of the PCS2 problem.

And when looking at Service Mode, most of the faults you see are going to be transient. A serious issue like a PCS2 failure is typically going to repeatedly generate relevant faults codes. So understanding dates, times, and quantities of those error codes is important.

Your phone app should show if you have free SuperCharging (under "Specs"). Frankly, if it were me, that'd be the last thing I'd be worried about.

Thank you for the advice. I just returned from the SC and my 14-50 adapter was bad. They used my cables and their adapter to show my truck charging at 32A. Alas, my early 1777777-2-D PCS2 is fine for now, and they sent me home with a new, tested 14-50 adapter for free under warranty since the defective one came with the truck.

As you mentioned, SC personnel explained that my truck did not repeatedly generate the fault codes for PCS2 failure, so my truck was not a candidate for new PCS2 and free supercharging. SC admitted that my previous visit was done without actually testing for 32V with their 14-50 setup, and that the advisor put me in line for a new PCS2 and free supercharging manually. As it was explained to me, the actual process for new PCS2 and free sc is pretty automated once they see the right failure codes. Since mine was entered manually, it didn’t go through their system.

Personally, I was never concerned about the supercharging fees. I simply wanted to have a formal, correct diagnosis and I received that today. Thanks again for the assist.
