lost commutate with tcm clear code u can drive it all day turn off come back drive next day same thing new battery rep;aced ground strap was green where is pcm does anybody know search says its every where except where it is any idea with the first problem

 

Info for you.
Lost communication happens a lot lately?
Read up on solutions?

 

there is no palk lite in fail mode your responce disappeared on the was it the d4 switch

 

Check your TCM connector for oil leaking into it.

 

i got car back i measured the data lines 60 ohms that's good. i cked the bus volts 2.7 high 2.5 low same at the tcm plug also has battery volts and ground i tried a different shifter just to satisfy cust samei am leaning to tcm isaking up

 

this is usually a pre-06 issue but bad coils will shut TCM off

 

can the car run fine and still cause this problem

 

absolutely. Been there done that. I had no misfire codes ever. Only a trans checksum code towards the end. Way i found bad coils was watching individual misfire counters

 

i could clear the code and drive it all day then off back on off next morning turn key on only trans fauilt no need to run car

 

What are ALL the codes you get from SDD?

 

i have found that if i warm up car code will clear untill it get cold talked to zf tech support he said it sounds like the tcm is having a issue now up to owner

 

You did not answer the question! You are just feeding us what you think is wrong. Do you have SDD or equivalent? Does your mechanic have access to it? You will be spending a lot of money firing the parts cannon if you do not have proper diagnosis.

 

it has a u1101 and get parking brk failure on cluster and shifter is also dead

 

U1101 can be caused anywhere along the CAN bus. Often the ABS module will get an internal fault to ground. Did you test the CAN bus wires for short to ground? Each should be over 10k ohms.

 

i didnt they have 60 ohm combined 2.7 high - 2.5 low side volts when i get it back i will test

 

i am open anything u have to suggest when u start the car from cold let it warm up to the first bar or higher u can clear the code and everything works fine test for short to ground if the abs is shorted to ground the bus line would stay down the bus has 60 ohms fault or not same voltage

 

Geez, learn to punctuate. I'm not even trying to participate because I can't make sense of your posts. No apologies for that. Communicate clearly, or bugger off.

 

Shows how little you know! There can be a dead short on one of the lines and still have 60 ohms across the two bus wires.

 

so u r telling me that the wire is shorted to ground... and still has the correct volts and ohms still comminates to all the other modules just not the tcm ....... i have never seen that it dont makes sence too stupid me i just a dummy like u say o and if u warm the car up a little the codes clears and no more fauilts the magic short to ground goes away . the abs controler with alot of problems r 97-05 and repairable not 06 n up ...... have a nice day

 

Wow, you got it all right! To help your understanding - If you get a ground fault on the line to your battery ground does your car stop? When you start the car the voltage increases considerably over battery voltage and can overcome a partial short in the ABS or other module. Then the fault can disappear until next low voltage condition. And yes I am having a very nice day.
