I have 2008 Dodge Caliber 2,0. Problem is, that ABS/brake liht is always on, when I drive speedo doesn't show anything, those two lights is always on, at first it sometimes turned on and then off, now they doesnt turn. I went to get those codes, at first it showed that right wheel sensor is bad, next code was that left (bot sides front) but they ar not active, the only ting is active that it cannot contact the ecu or something, i'm not good at these things. Sorry for bad english, I' from Lithuania So what should I do, can I put used sensors? Cuz new one sensor in shop cost about 120$ for ea.. Could it be problem in main ecu? or it is only abs ecu fault?

The speedo, cruise control and ABS are all tied into one of the speed sensors. I am not sure which one is for the speedometer, but both are used for ABS.
It is odd that both fail together, but it could happen. You might check the connection at the PCM and make sure it is tight and not corroded.
I had a front hub replaced on my Ram and the new sensor was bad and my cruise control wouldn't even power up, so anything is possible.
Can you clear the codes then see which ones come back and post the codes here?
Thatks for answer. The main thing, that it can't erasy that codes. It shows that there is no conection to computer or something and I don't know in which or in abs or in main ecu. I think would it help to overwrite ecu proram and maybe these problems should gone. But on the other hand it would show speed or someting. where could i find speed sensor or is it in both wheels?
Once ABS faults, it goes offline..... you will notice that you check codes but once you start driving and try to use data live view it will say connection error because ABS shuts down and becomes inactive with vehicle running.Changed the hubs/bearing on my AWD as PM, the ABS sensors were stuck in front knuckle and had to tap them out once I had knuckle removed.I reinstalled new ones once I changed out bearings and forgot to connect the right sensor , this lead me to ABS/AWD disabled and going offline/no CC either.So lx is correct.Reconnected right and presto back online once I cycled key.I think Wheel sensors are only for ABS and Speed is collected off the Output shaft sensor(s).
To clear/re-access ABS you will have to turn off,then KOEO otherwise If you start it will disable ABS/AWD and it will go offline.If you fix sensor it will see it and clear MIL and operate properly
Hey, still having same problem with abs/brake light and speedo. I have changed both sensors, connected coretcly everything looks god but abs/brake light wont turn off and speedo doesn't work.. tryduck had explained what to do, but I don't understand what is KOEO
You could have a corroded power distribution box (fuse box). You might try removing it and checking the bottom for any signs of moisture or corrosion. There may also be a relay in the box that could be bad. Their should be a fuse/relay diagram in the owners manual.
Have you rescanned it to see what codes are stored in the PCM? If it lights the light, there is a code in there somewhere. If you can post the codes here, we might be able to find out what the heck is going on.
There is a chance your encoder ring is damaged causing a no reading at sensor.Have you jacked up car and live viewed each wheel as you spin it to ensure your atleast getting a reading of movment? As long as you do not start vehicle it will not disable abs /brake system yet allowing you to use live data to see if your sensor or bearing encoder rings failed.I wouldnt jump to ecm yet unless it has been messed with. Any repairs been done to vehicle within few months of issue happening,..Check your battery cables and if wire harness has green tint replace them both pos /neg battery harness comes as kit.You first have to rule out most simple.ABS combined with no speedo have to make sure ur at least getting a reading to ecm.If you cant live data to check each wheel is sending data then check with meter.then move up the line till you get to ecm, check ALL fuses are working first (with meter as looking at fuse is not 100% trustworthy) not just one.
This isn't just a brake issue is see , just now looked at pictures of all codes so i would be looking at a connection issue in engine compartment maybe, what was done to car...repairs around when started or hitting a animal curb....anything around time this started happening? Did all this just start happening all together or have you been letting issues go till abs issue started happening?My 07 battery is still going, when did you have battery replaced and did they inspect harness for corrosion. You need a better scan tool/laptop program to dia/repair. These scanners are a money scheme as they pretty much only pull codes unless u have the much higher end ones/laptop programs.This looks like a issue to in depth for adverage owner to repair on a bbs forum IMO.Unless car had been worked around start of issue which would lead to something being left disconnected. Possible this is only a job for a shop to chase down and repair.Dont waste money tossing parts at it.While I wouldnt take anything to dealer/pepboys,firstone... unless it was for recall/warranty work , find a shop to help you sort it out.
I would have to go with others and say you should easy your pain and take to shop. Dont blame your vehicle as anything man made can have issues not just a caliber.Have come across about every make of vehicle out there and all of them have are subjected to become a pita .It isnt just one model one make.....
