ABS light and more..

Driving to the Keys at a speed of about 45 and very gentle braking (approaching an intersection) my Solera acted up : although I was on the brake pedal it wanted to accelerate. Could override with a lot of brake pressure and turned cruise control off. Then 3 yellow lights came on: ABS ESP and ASR.
Braking is ok - it feels just normal.
I am hoping it is just an ABS malfunction- manual states with ABS failure EPS and ASR as well as cruise control are deactivated.
Disconnected car battery for about 30 min and then back up again: while still at rest lights still on, as soon as I started rolling down the HWY all lights went off - and came back on after about 10 miles.
Did not dare to try cruise control.....
Any similar experiences or inputs other than see mercedes dealer? (Pretty far away)

Thank you Hans

I believe if memory serves, that a member had a similar malfunction and reported the cause on here. I think it turned out to be a faulty ABS wheel sensor.

In the auto world that can be an indication of the faulty sensor. Sometime it just needs some cleaning off. They ar3 usually around where the brake rotors are so th3y get crude up.

Solution to your ABS etc lights

We just went through this this past September and it was the rear wheel sensors that needed replacing - we just got ours under warranty by 9 days - very lucky. It fixed it all and it has been great since.
An easy change when you are near a shop that can do this for you, otherwise we had to limp to the nearest one - was ok to drive, just very frustrating with having to stop frequently and restart. It had to be a Mercedes dealer who dealt with Sprinters too as we found out it can not be a car dealership.

Good luck
We have the 2013 Solera 24S

Thank you so much - Still Kickin - good to know now that the warranty is all out.
Do you know which scanner is the best for the sprinters? I would like to get the pro one as my husband is a mechanic.

To heck with the ABS light. I would be more concerned with why there was acceleration while I'm on the brakes.

Still parked in the Keys- next mercedes service is far away...
Got a scanner - it is reading the code P068 A (powertrain, computer, aux outputs - iso/sae controller) and U140C ( Network).
In addition running a system check with the scanner I am getting 5 "not ok" messages like:
Mid: $03 TId:$d4
02 bank 1 sensor3
Min 32.768 max 40
Do those help at all, worth posting?

There's also an ABS sensor on the differential. Costs about $10, takes five minutes to replace. I had one on our old RV that got busted by road debris if some sort. Should be on the top front of the differential and has one small bolt and a clip holding it in. If you hook up a gage to the computer port, the error code should tell you what's throwing the error and allow you to reset the system. Most auto parts places now will check the code for you at no charge.

Ok, you did read he has a MB sprinter chassis right. And you're sure about that.

When you're getting multiple codes, the first thing you need to do is reset themdrive the vehicle and right after you get the dash warning(s) pull over and run the scan again. Then, compare the second readout with the first. If some codes have dropped off, that is an indicator that the dropped codes were generated after the code you get the second time. It is common for multiple codes to trigger after the initial trouble codethe first time.

Then, if you post that code, we can do a look up. Some on here are pretty good with finding MB trouble codes. Good luck.

Still Kickin thank you for your help!

I did exactly what you proposed - reset my codes, left the campground and 2.1 miles later loghts came on.
Rin a scan again - and get exactly the same readout.
Back in the campground....

But what did the codes indicate? That's what needs repair.

Ok, sounds like you have the codes. I think because you have multiple trouble codes, there is probably a malfunction in one system that is triggering the others. For example the "bank 2 sensor 3" means the main engine computer reads the second cylinder bank (V6 has two banks of three cylinders each) triggered the third sensor in the exhaust stream from the engine.

Can you post the exact code faults as your scanner indicates so others can possible guide you ifthey have expierenced similiar fault codes.

Hans,

U140c fault code you mentioned looks like a right rear wheel sensor issue. Just a hunch, but from what I read, the faulty wheel sensor could be tripping the P068A code which is the ECM

See: P068A | CAR OBD CODES

Everything I read is that the P068A relay is tripping to "early" giving you that code. It seems that maybe the RR wheel sensor U140C (which is in the drive train) might not be supplying "input" to the ECM causing the P068A code.

Just a hunch.
