OBD2 Scanner W208 CLK430

I need to reset my SRS Light and also Reset the window reg on the passenger side of my vehicle. I purchased an OTC Genisys 5.0 which was $2,200, it does a great job, but it will not clear these codes after the battery was disconnected.
What is a good Scanner for these cars that will do it all.......

To reset the SRS light or window you should not need equipment ?

Once you have found the root cause of why the SRS fault is on the dash, it is cleared by turning the steering wheel all the way to the left and right. It will not clear using the equipment or if you have not fixed the cause. Usual reasons are ABS sensor / CPS sensor or Brake light sensor.

You also cannot just disconnect the battery and connect back up without performing a car start up reset, which is probably all that is wrong and why your SRS light is on and your window does not behave correctly.

To perform the reset follow my steps below:

Preparation Steps:
1. Make sure your steering wheel is straight.
2. Make sure your windows are all the way up
3. Make sure your sun roof is completely closed (if you have one)
4. Make sure your parking brake is released.
6. Turn off your stereo and make sure you have your stereo's Anti-theft code.
7. Turn off your heat/AC blower
8. Turn off your lights
9. Make sure your doors are UNLOCKED.

Now, disconnect battery 30 secs and then reconnect.
Get in car close the door and turn the key to position 2 (Just before you start the engine but do not start it)

1. Resetting your windows: Bring down both windows at the same time by holding the switches just before the click that brings them down automatically. Once both windows are all the way down make both switches click by pressing them all the way down and hold them for 3 secs (This lets the ECU learn that that is the end of the window track and it records it in memory). Do the same for closing the windows by holding both switches and making them click once the windows are all the way up.

2. Turn on your blower and make both sides go to 72 deg (if you have this typr of heater control) by pressing both up and down buttons at the same time. This will calibrate the ECU
3. Turn on your stereo and enter you stereo code.
4. Pull the sun roof all the way back and all the way forward then up and then done.

6. Turn all you lights on and off, including your fog lights.

7. Turn the key back to position 0.

8. Turn on your engine. You will get 2 malfunctions, your ABS and ESP lights will be on and must be calibrated.

9. Calibrate your ABS and ESP systems by turning the steering wheel all the way to your RIGHT and then all the way to your LEFT, then bring it back to the middle. Notice the two yellow lights disappear from you dashboard.

10. Let your car run in idle for about 5 minutes and then take it for a spin. Remember your ECU is still getting all the readings from all the sensors on your car so drive slowly first then faster... and so on.. you are basically teaching your ECU how to handle your car.

Lastly you should not need to purchase such expensive diagnostic equipment at $2200 !!? you will never get that money back over time.
I have used a cheap ebay Bluetooth OBD2 that has worked on 3 cars that reads and resets all the codes with no issues that cost me $4. The software is free and installed on your phone / tablet and is linked on-line for live updated info too...

HI

The scanner is generic and will work on most Mercedes and most cars. The difference you may find on your 99 CLK320 is that you have a round plug in the engine bay rather than the rectangle plug inside the car, but that fine, just buy the round pin to square adaptor and it will work. I have taken the plug adaptor apart and there are only 3 cables that need to connect to OBD, then via bluetooth after you have paired you can see the data using an app like Torque.

My 1999 CLK 320 has both plugs. OBD II codes have to be pull from the inside one. All other codes has to be pulled from the 38 pin socket.

AIEK:

I have repaired everything on my 2000 CLK 320, A208. New front end, repaired the convertible roof so it will operate, and many other mechanical items. However, the ABS and ESP lights are still on. I was going to purchase a scanner to diagnose and pinpoint the issue. (Faulty or dirty wheel sensor, etc.) Are you sure that if I follow your step by step re-calibration, it will turn off the those trouble lights and stop the information center on the Speedometer cluster from telling me I have three problems, ABS, ASP and BAS?
I do not want to take the vehicle to a shop to read codes, when I could spend an extra $100 to own a more extensive reader. I already have the Bluetooth one, but does not read ABS codes.
Thank You in Advance!

Carl

Hi Carl.

Follow the above instructions precisely.

You do not need any equipment to do this, so what have you got to loose?

If it doesn't work then you'll know you have to investigate further and I suggest then you start your own new thread, as this one is quite old.

Yes, this is a pretty old thread but I kept researching everything before I bought a scanner or paid a garage to run a code. But thanks! You're right! What have I got to lose! THANKS!
