Welcome to the site first of all....I hope we can help you with your issues.

IMHO, there are a few items when you first get a smart car that new owners should do to check what condition their car is in.

Reluctor rings are one of those to check as the above post has suggested.

Checking your ground connections starting with the obvious, battery then out from there.

Checking the condition of your SAM unit for water damage, corrosion etc etc.

If you research typical issues for your year and model you will find the topics to hunt for.

These things aren't always an issue but if you take the time to just check then perhaps you'll be problem free etc.

Again welcome to the club and site.

Hi everyone

Thanks for all your advises, I follow them

1 Pairs of reluctor rings are ok

2 Battery ok, was checked with Scanner Icarsoft before mention it.

3 I bought Rear Left ABS in Ebay


As result was replace Abs sensor and fit very well. But after that my idle hands disconnected an transmission sensor back upper left, as consequence cleaned ( Electronic Cleaner ) and reinstall by myself and when turn it on the engine behavior changed completed in the dashboard intermittent showed letters gearbox obviously when apply each letter less parking P also Left Side show it Two wrenches the same intermittent modes. 

Try after to reset scanning and disconnect battery and nothing happened.

Well, guys Its my unique car, appreciate some advises or procedures to do. 


These are his faulty codes

1-  P0700 Clutch Protection Function

2-  U0103

3-  B1101
