Mercedes 210 ESP Problem - Road test not performed

[gigabyte]

Hi friends,
First the car- Mercedes E-class W210 220 CDI 2001
Car had Lateral Acceleration Sensor error. I changed with a working one and the trouble code disappeared.
Then I took Driving Test from the Control Unit Adaptations.
I post pics from the steps of the adaptation.
After Adaptation New trouble code appeared:

C1540-007 Driving Test:
Road test not performed.

I can't erase this and I don't know how to do the road test.
Any Help?
Thanks

this happend to me a night mare couldnt find any info anywhere about how to get it right.
now i may be wrong as it was a long time ago and i had done everything i could think off but give this a try.
get in the car and do figure of eight in a car park ,i think it was six in total and then drive straight line and stop .light went out fault code gone
if that dont work try full lock right and do six circles and then full lock left ans six circles. straight line and stop.
im sure i will be corrected but thats all i can remember.

[gigabyte]

So, I just have to drive the car in circles and the code will disappear? Did you fix your problem with this solution?

[simon77]

the car was repaired with one of the solutions but exactly how i cannot remember .if you dont get any info here i will call somone in mercedes tommorow and get the info for you.

[gigabyte]

Hello,
I just tried the eights and the circles but not success!
Any suggestions?

[mercis]

you can all info about activate esp on WIS read

[gigabyte]

Yes but I can't find it :dontknow:

[simon77]

asked mercedes and my guy is not there but they toldme somthing to do with driving in a figure of 8 until it swithces of but the exact details i can not get as my guy isnt there sorry!

[Dajan2009]

Here it is. :) Cheers

[gigabyte]

Thanks
Here is nothing about to drive in figure of 8.
I'm really confused but will try this

[simon77]

its just a test program of esp sensors not what you need

[gigabyte]

I agree.
Can you get the details from your man or have to experimentalize with eights?

[simon77]

i have to wait for him to come to work i dont have his mobile no.
if only i could remember but im sure now of the figure of eights .

[simon77]

i have a c220 in the shop if it has the same sytsem i will give it a goe on monday and let you know.

Thank you very much! I appreciate your help :)

hello
u have to read actual value of component b24/2 esp lateral acceleration sensor

move vhicle firmly by hand in crosswise direction
read the actual value
the actual value changes with movement
if not
check the power in the soket it should be 4.75-5.25
if all fail the problem in the esp and bas control module

[simon77]

he dosnt have a problem he has just put the car into test mode . he needs to know how to get it out of test mode.
there is a special procedure to get out of this ie: drive in straight line turn sterring to the left then right ect

[agabna]

yes
but he change that sensor and he should make adaptions for it
the esp adaptations should be done if (road test) if u replace the lateral our the yaw rate
it unless it worked the ecu will not shut the test
and move the steering left and right it for the steering angle sensor
and that information is from das

[agabna]

but if u whant just to end the test their is 11 steps for it
i can send it also if u need it

[agabna]

hello
read the 2 file and if u need more pls tell me

[Dajan2009]

Sorry for being late, had some working time through the day.
In the file attached in post #9 is described a usual procedure what you need to pass after replacing the Lateral acceleration sensor, formerly known as "Road test". When You read it carefully, you can imagine the path a car need to do for passing the test. It is not a "8" shape, or circles of any kind, but is a travel composed of many "part of a circle" that alternate in opposite ways.
..Introduce cornering after a few meters (left or right, steering wheel

angle not more than 360 ? ) and a quarter circle, then countersteer...
I do it every time after exchanging that component and it works, just maintain your speed about 6-10mph and with fixed throttle. I don't realy know why they lcall it sometime "Functional check of ESP yaw rate and lateral acceleration sensor" in WIS and sometime just "road test" in DAS, but i see it is the same thing. If you need something more just ask.


Ciao:ciao:

[Dajan2009]

hello
read the 2 file and if u need more pls tell me
Can you please tell me which program I can use to open this file?
Thanks:dontknow:

[agabna]

hello
it screen print out from das u can use windows (picture and fax viewer ) our any image program
it .bmp
and here is other type of file

[gigabyte]

Thank you all mates.
I will have the car after 3-4 days and let you know the result.

[florinyes]

Please let us know the outcome...

[gigabyte]

hello
Not success...I tried everything you told me and the not performed test error won't turn off....Really don't know what to do more :dontknow:

[augustinbz]

try to disconect the ground battery lead and make again all tests described

[simon77]

if i can get the mercedes i have here sorted and running corectly tommorow i will put it into test mode and figure out how i did it the first time round . j havnt forgot just havnt had time.
regards

[agabna]

hello
what is the message u got and what is the fault u have and u have to give more information about what type off scanner u use if u r using other than das it will need other way
but if u use das pls inform i can help u more

[gigabyte]

Thanks,
I'm using DAS, there is more info about the code in the first post C1540-007 Driving Test:Road test not performed.

[Dajan2009]

You have to just keep on trying! It will be a pain to fulfill the test the first time, but you will became good at it in few years. Sad but true. Of course, I suppose your other actual values like acell. sensor, steering wheel sensor, ABS sensors, engine and trans free of faults are OK.
Cheers:ciao:

[agabna]

hello
to short ur time u have to check the acual value first
for the system (switches+rpm senor+esp sensors+steering angle)
if any sensoer is not working the test mode will nt shut down
some times it close the test mod after actuations which can be done after erasing the trouble code
can u give me the chs no for the car

[dunnnia]

Hi,check all actual values of all sensors,someone did'nt work corectly.

[agabna]

hello
to end drive test mod is not the same in all the mb cars it depends on the car eps system and year model
here is example for s class 220 065
it for using with the das system

[agabna]

if any sensoers doest work correctly try to change it by other one to end the driving test all the sensoers should be 100%

[gigabyte]

All sensors seems to be ok but I'll check everything again

[gigabyte]

Hello friends,
Finally I fixed the car. Now everything is really ok :) Thanks to all of you for the help!

[simon77]

please let us know what you did

[gigabyte]

So, the second sensor was damaged too, it was second hand, not new. So for that reason the test didn't switch off. Today another e-class came to me with the same sensors. I replaced it just to turn off the Test. It gone after a little driving around. Not a figure of eight or circles. Just 1-2 cornering to the opposite direction and one 90 degree cornering and after that it turn off. So the above pics from DAS and WIS are correct. Another thing is that everything must really works. Actual values ware ok with the second hand sensor but it seems that something else didn't work in it. :)

[florinyes]

Glad to hear you got it sorted matey..

I'm having a similar problem on an 02 C320. Saying Roat Test Active.

[agabna]

i need more detail for you car type(202-210-203-220) our the first 6 diget in the chs to give you full detail to fix it

[lovelyirshad]

this is very easy function man just active the drive test remove star diagnosis press esp off switch and drive withing 10 sec you turn steering up to 90 digree and the light will flash and then goes off
that it

[Downunderdude]

Apologies for resurrecting an old thread, but must give thanks to Dajan2009 and agabna for your very helpful information. Thank you, much appreciated.

Had a frustrating day with similar issue on W168 03 A190. DAS would not clear fault / light and fell into "Road test not performed" loop. Tried L-R-L-R steering angle reset, driving in 8`s and circles unsuccessfully.
Couldn`t find road test requirements in WIS but all good now I have learned correct procedure. :) (http://www.digital-kaos.co.uk/forums/member.php/121529-agabna) (http://www.digital-kaos.co.uk/forums/member.php/69304-Dajan2009)
