@  Francesco : (27 July 2015 - 08:10 PM) Or wheelie bars
@  Mike T : (27 July 2015 - 08:07 PM) Preferably, use a larger vehicle.
@  Francesco : (27 July 2015 - 08:05 PM) I would think a trailer is your only option. The physics is just wrong in a couple of dimensions to be hanging 300 lbs behind the rear wheels
@  marchanna : (27 July 2015 - 07:27 PM) Check it out: can-drift.com
@  marchanna : (27 July 2015 - 07:21 PM) It's an electric drift trike. I wanted to see if I could fab a vertical rack on the back of the Smart. The trike weighs about 200lbs - I could probably build an aluminum rack as light as 50lbs - but that still the exceeds the tongue weight of the hitches, thought maybe the towing bolt holes could hold a little more weight.
@  Francesco : (27 July 2015 - 04:50 PM) even the trunk weight is recommended to be no more than 50 kg...
@  Francesco : (27 July 2015 - 04:49 PM) Wow, I have no idea what you're attempting but that sounds like too much weight for the rear of the smart altogether, not just for the two bolts.
@  marchanna : (27 July 2015 - 08:01 AM) I want to hold about 300lbs across of them.
@  marchanna : (27 July 2015 - 07:59 AM) Yes
@  Francesco : (27 July 2015 - 07:43 AM) Vertical?
@  marchanna : (27 July 2015 - 06:32 AM) Anyone know how much load the towing eye bolt hold in the rear bumper of a 451 can carry?
@  NelsonSmart : (19 July 2015 - 11:59 AM) The ECU computer will have to be set with Star or Equiv to get light off.
@  Surturiel : (19 July 2015 - 10:10 AM) all, and all, the only damage was sustained by the tire (that was old already)(aside, of course, from the airbag...)
@  Surturiel : (19 July 2015 - 10:09 AM) yep, talk about overreaction. i hit the curb, the airbag blows up on my ear, and the car shuts down...
@  dmoonen : (19 July 2015 - 06:58 AM) Lol air bag went off? That's a bit drastic. The car shuts down in a case of an accident so cycling the key makes sense.
@  Surturiel : (18 July 2015 - 09:43 PM) (with the airbag...)
@  Surturiel : (18 July 2015 - 09:43 PM) anyone have by any chance an used passenger seat for a 450 fortwo, passion? (dark gray)
@  Surturiel : (18 July 2015 - 08:08 PM) turns out that you have to turn everything ( including the hazards) off to get the car to work again...)
@  Surturiel : (18 July 2015 - 08:07 PM) (I mean, the car just DIED. I was there, stunned, trying to figure out why I couldn't get it running)
@  Surturiel : (18 July 2015 - 08:05 PM) (that thing surely is loud, got me half deaf for a while. Also, the whole smart crash routine got me REALLY startled)
@  Surturiel : (18 July 2015 - 08:02 PM) but do I need to do anything aside from replacing the airbag to get the light off?
@  Surturiel : (18 July 2015 - 08:01 PM) springs and everything
@  Surturiel : (18 July 2015 - 08:01 PM) will service the suspension soon
@  Mike T : (18 July 2015 - 07:17 PM) check the toe setting
@  Surturiel : (18 July 2015 - 04:41 PM) (the front wheel and suspension are fine, the tire needed to be replaced)
@  Surturiel : (18 July 2015 - 04:40 PM) so, aside from needing to replace the airbag itself, do I need to do anything special to get the light off? (time to find a used passenger grey 450 seat)
@  Surturiel : (18 July 2015 - 04:38 PM) (the seat one)
@  Surturiel : (18 July 2015 - 04:38 PM) but my smart, being the overprotective nanny that it is, decided that my integrity was at risk and BLEW UP THE SIDE AIRBAG !
@  Surturiel : (18 July 2015 - 04:37 PM) i hit a curb (because I'm a blind dumbass that misjudged the curb height)

Hi, I'm on the search for the wiring diagram for my 05 Smart if anyone has one that would be great I'm trying to trace out my shifting problem which only happens when it's wet out and the dealer can only get memory codes from the shifting sensors they claim I have an open circut on one of the wires ( it never pulls an error code when we bring it in of course ) they could trace them but at thier hourly rate I can do the same but a diagram would make it easier.TX :D

As far as I know, there isn't going to be any one wiring diagram for your smart. There are dozens of wiring diagrams for various systems. With literally thousands of wires in the car, just finding the right diagram is going to be a nightmare. - Steven

I presume from your comments that the car does report a code sometimes, but when at the dealership, they don't see that code. How do you know this? Are you using a Scangauge or other reader to see the code? What is the code number?

If the car throws up a fault code, that will point to the sub-system they should be checking. With that knowledge, along with the MB/smart dealer's Workstation Information System, they should be able to get to the area where the fault/short/open circuit is and then do a physical sort.

Is this still about the same problem you reported on Dec 4? Can you maybe induce the failure by taking the car through a spraywash near the dealership?

Did they check the wiring connections at the clutch actuator? That's a known weakness.

Good luck...

The shop had these codes come up when it was in Dec 4 but they didn't appear after fixing it so they thought it had something to do with the faulty SAM. But it's not, so they hooked it up again to check but by the time I get it to the shop everything is back to normal and they only get memory codes they tried spaying it down and they drove it around for a couple of hours but came up with nothing.checked connectors etc. They said they could pin point it if it showed the shifting fault when at the shopThe codes are PI925 and P1850 for the gear position and trans speed sensor It seems to be getting worse when it acts up now too. It falls into neutral and I have to turn off the car and restart it to reset the gears and when it happens it fails 4-5 times in 10 min then it drives like nothing happened

This sounds like one of three things... a wiring fault in either the SE drive or the gear selector/actuator; or a known flaw in the brake light switch that can cause the transmission not to go properly into/out of reverse. Unless you are a dab hand at wiring and electronics, best repair is just replace the offending unit assembly.Those are the three sub-systems to concentrate on. In my opinion, of course. Oh, and also inspect that shift actuator wiring at the connection beneath the car.Good luck!B)

Have you ever removed the shifter housing, for example to install something like the push button start I sell? I only ask because I wonder if some wiring right at the shifter got compromised. I know it doesn't have anything to do with weather there... but maybe wet or dry is just a coincidence.Just thinking out loud. - Steven

I had the same problem last week and MB replaced the steering angle sensor, the G sensor and when i said that these items have nothing to do with the transmission shifting, they finally replaced the transmission motor that acually does the moving of the shift rings, not the acutator. Runs good now.Jim

Well I order the FF310 fault finder from General Technologies yesterday and should be here by the end of the week. So I'll see how that goes. The only time we took the shifter apart was the other day to look for any wires that maybe damaged and the shifting error happens while were driving reg not from going from reverse to forward and also happens in Auto as well.So for now we have siliconed the connectors to see if it might be water entering them, now we just have to wait for it to snow again (yuk) Spraying it doesn't trigger it.And this gadget I ordered is supposed to find broken wires, open circuits etc. in just minutes so we'll put it to the test when it comes in.If that all fails then I guess we'll start replacing sensors etc.

Did your car pull the same codes as mine?

That FF310 fault finder appears to be a pretty slick tool! Excellent opinions on the 'Net, and the principle is simplicity itself (if not the actual technology). Please tell us how you make out...B)
