No can bus communications.

Any pointers . Conductor plate was just replaced

 

That is a vintage DAS, won't help you much like new versions
check the connector to transmission, might be full of transoil
there was a recall for that because of leaks

 

well i did change the conductor plate . cause i was getting nothing . new oil . etc . i do have abs , abc .esp light because if you saw my other post . the pump self destructed . as of right now i have bypassed the A/c compressor and power sterring , abc tandum pump . i will make a wright up with the pictures and the belt that i used . i can start the car let it run . but thinking due to the modules detecting tandem pump is not running . might be casuing this problem . and or what not . i will try and disconnect the abc fuses to see if it lets me get in there as it seems the transmission is in limp mode .

 

 

So i removed the ABC module . And iand removed the fuses. Got rid of the ABC light on the dash. Used alltel getting error code for no can bus.but then got this error and also started having code for electronic shifter . When i engage D Or R . Its a hard shift .the system detects the shifter going in to drive and reverse . But when i try to test the solinoids it automatically aborts and says d is not engaged .

 

You have too much going on at one time. You need to get the vehicle into a known condition. This means replacing all devices that need replaced. ABS unit, tandem pump, etc.

Get the vehicle back to the last running state. When did you last have the vehicle running, with no faults, codes or error messages?

 

I just got the car a few weeks back . The car would only shift to second . Who ever owned the car sold it . And i got the car from the person that bought it. I was told needed new conductor plate . And new pump . After removing the pump .i found that 2 lines had broken to the pump . Hydralic line that goes to the front right accumilator over the transmission and the line that connecets to the vibration dampner . Then after further investigating i came to notice that lower loop hole on timing cover broke for the rear bolt mount on the pump. So i bypassed the pump and the ac compressor .with several trips to the auto parts . Finding the proper belt.So i can start the car . I havent attempted to move the car as the car is sitting super low in the front and trying to figuer out to raise the car by wedding small peice of wood some where on the bith sides of the suspension . and drive down the street and see if i get a different reading . But still trying to figuer it out

 

OK, thanks for the background. You are in the middle of an expensive discovery process. If I owned this vehicle, I would throw parts and money at it until progress started to be made. My recommendation is, either throw parts and money at it, or sell it.

 

I definitely am getting it running . Ive already spent money got the pump. new fluids .conductor plate . Etc . I think i need to try and drive it a see if the car reacts different since new plate installed . Only problem is the car is sitting low in the front . need to figure out how to raise by wedding small block of wood some where in thr suspension...

the other day i was working on a R500 and it had a bad speedsensor .wire broke off completely. After installing new one had to reprogram ESP module becuase that car shot up to 208 miles an hour while the door was open . After flashing esp module and driving the car it all reset . So hoping i might need to do that .

Floor it ... lol

 

Consider prioritizing getting the suspension fully sorted before finishing the transmission situation.

 

i've never heard of any kinds of abc issues causing a transmission to be inoperable. i believe you have two seperate issues. i would focus on the transmission because whats the use in fixing the suspension if the transmission needs replaced...

 

I agree with you also . Multiple issues . That im tackling all at once. I was 🤞crossing my fingers hoping changing the conductor plate would of fixed the problem with the transmission . But same issue remains . When i drained the oil it was dark and smelled cooked .i have some pictures will upload now

After beimg put back together

Old plate

 

So what do you think. looks like the previous owner put some additive in the transmission or , transmission fluid was never changed?

 

Update . If ur just tuning in . I just recently acquired the w215 .so i have been chasing down the issues all at once .

What ive notice is who ever had the car before me did everything im doing . And did a sloppy job at putting things back in the same place or at least secured to the location they go to . For instance the ABC module . Some one already had disconnected it . And never inserted in the slot where it goes . Today i went for the TCM found the same issue also . I guess they opened up the TCM and cleaned it up . I did find small traces of oil left over the plastic casing . After really analyzing the TCM i can find Green corrosion on the outer pins .when looking at the board i can see small traces of what looks to be like water damage on the bottom of the green board . There is a aluminum cover that is soldered on to the board that also had signs of rust on the board and solder points . I used contact cleaner in hopes that it would of corrected the problem .

Before i was getting a code for the shifter and i was able to clear it . Now it wont clear . I wasnt getting that code till after i replaced The conductor plate . So assuming the conductor plate allowed me to see another issues that wasnt there . After removing the TCM and cleaning up . Now code wont clear .
I have a new plug for the transmission that i will install in the next couple of days .
When i serviced the transmission . I didnt have the plug on hand . So as of right now its pointing at the TCM and Esp . Because the shifter code is related to wheel speed senor detecting rough road or some thing along those lines. But i will keep you guys updated on my progress. Right now my Star is down due to Rs232 cable Plug giving no communication to multiplexer error . Thats why im using the Autel till i can repair or order new cable .

thanks for Tuning in . Till next time

 

What’s up guys hope every one is ok with this CoVid -19 issue. Update On the project.

so since my last post I had to return to the work force moved and the car was put on hold. But now with all this free time we have. I was able to get back on the project. I’d like to report the TCM was damaged. And didn’t get around till messing with it till last night. Ended up getting a TCM swapped it out. And what do you know. It’s alive

 

TCM seems to have been the issue. Today I will test it out and go from there

 

It runs. Goood. It’s Alive.
