HV System Workshop



I caused this HV System Workshop code by tinkering around last night. The car runs and charges fine. Anyone know if I have the ability to reset this myself?

"Tinkering" doesn't provide many clues as to allow our fellow smart CSI members to do their thing?

Don't think that you can "tinker" the code away without the STAR Diagnostic computer BUT here is a Zombie thread on the "Workshop" code from January 2015 - https://www.smartcarofamerica.com/forums/f170/12-volt-battery-died-90058/

12 Volt Battery Died - Update
Took it to the dealer, it was the DC to DC converter that was faulty.


As with all things smart and smart ED - YMMV . . .

I was looking at putting a simple harness on for when I need to attach a platform or tow a small trailer. I opened the right side access in the back to see if all of the tail light connections ran through one side or the other. I disconnected a really big connection on the theory that if it was the right the tail lights would stop working. Bad theory.

This is what I unplugged and plugged back in.

Looks harmless but that "really big connection" may have been sending a message to the HV (339/391V) side and ED was only trying to protect you from yourself?

I have factory trained technicians who work on cars daily for a living, including electrical work. When dealing the smart EV (and any other electric vehicle for that matter), the voltages can get high enough to kill somebody. So please be sure you know what you're doing if tapping into any wiring, and I can say from my own personal training that if there are any wires wrapped in orange --- DEFINITELY leave those alone. Those are high voltage lines.

For certain jobs they let the car sit and place cones around the vehicle as a warning for any curious george's to stay away from the vehicle as the HV battery may be removed, or exposed, or other components.

I have provoked that message by compromising the CAN bus with an incorrectly assembled battery test unit during testing.

In that case, removing the offending test unit (from OBD2 port) and power cycling the car fixed it.
I suspect youíve already effectively tried that, though.

The wires shown in the picture are absolutely NOT high voltage wires - they are part of the 12V accessory power or LIN communication syatem or the 5V CAN communication system and Chris was doing nothing unsafe by disconnecting them. Even disconnecting the big HV (orange) connectors (as I have on the A/C compressor on my Smart ED) cannot harm anyone unless the person deliberately goes out of their way to close a circuit between the + and - poles of the battery pack i.e., DC is not like AC - closing a path from a single pole of the battery pack to earth will do absolutely nothing.

Or more simply, unplugging any electrical cord your home is probably more dangerous than unplugging a HV electrical connector in a Smart EV - especially since there is an interlock syatem that cuts power from the battery pack off immediately upon the connector being pulled.

Most of the rather extreme service measures imposed on Smart Service technicians are the result of lawyers, not electrical engineers. If the car's keyswitch is turned off than nothing in the HV syatem outside of the battery case is energized. There is also a separate "service disconnect" in the Smart becsaue of "lockout-tagout" requirements of OSHA or other countries occupational safety and health regulations.

There is entirely too much hype and scaremongering surrounding EVs by electrical physics-illiterate people in the "technology" industry. We are even seeing people thinking that if an EV goes into a lake, people swimming nearby can get electrocuted.

There is a scanner. The "iCarsoft i980 scanner" - that can be used to read and clear MB car diagnostic codes - probably including the "HV System - Workshop" one.

As warranties expire and our already unfriendly local MB dealers start refusing to work on Smart ED's, I really look forward to this forum being a place where we can obtain technical and safety information on repairing our Smart ED's. People telling us flatly "no user service should be attempted" are not going to be very welcome here in the near future.

If you want to work on your car it is your legal right and I'm not judging you for doing it. I was not intending to suggest that the person on this thread did anything they weren't supposed to do.



My message was to the general public who may stumble upon this thread and then take the seemingly logical decision to start working on their own car. Most folks will probably be fine because they will take the necessary precautions.



I've been trained on HV vehicles since 2010. Taken the sales and technician coursework. Those courses scare everybody to death because it's better to be fearful and take precautions than it is to make a critical mistake you can't ever make again. The purpose of my fear tactic was to scare people into taking the necessary precautions. Getting zapped by 400 volts is a mistake nobody can afford to make.

All the gloves, the cones around the car, the refusal to pull high voltage wires and begin work immediately, etc, is all just precautionary stuff. Super extra precautions are taken when working around HV equipment. Just be careful, that's the only point that I'm making. I'm not judging anybody.

Good words. I have a background in power and electronics. So I know when to stop with my tinkering. Itís good to remind people to be aware of the high voltage potential of these cars. These forums can show up on Google searches so itís good to float some warnings out there about the safety issues when it comes to EVs.
