I am in need of some serious help again. I need to know if i should go to the dealer or start with an ABS ECM rebuild. My vehicle is a 2000 S80 2.9 with 120,000 miles. I live in Chicago, i think i have an ABS or ECM problem.
A few days ago i got "Brake Failure Please Stop ASAP" error and the ABS,Brakes,and STC lights all came on. So, i pulled over and tried to restart hoping it was a computer fault. Stopping was fine, brakes were fine. I check the brake fluid and everything else and it looks completely normal.
Upon the restart, the car fails after starting. I restart again, it sputters and dies. I try to start again and it won't. So i leave it for about 10 minutes and start the car. It starts fine with zero errors and i drive to work.
Later i drive home and it does it again, this time i dont stop and the car continue to drive fine. However, i have no engine temp,tach,odometer, or cruise control. After i get home i restart and its cleared. Tonight i drive to Wisconsin. Upon trying to restart to come back to Chicago, i get the whole Christmas tree of lights plus more.
Now its "tranmission service soon" something like that followed by "Brake Failure Stop Safely ASAP" and Check engine, ABS, STC, and Brakes are lit up. Car wont run well after a restart, and after pulling the keys, the lights for the transmission shift indicator next to the shifter stay on?? I try to start multiple times and it finally works fine again.
What on Earth is wrong? Should i just rip out the ABS control for rebuilding? Should i spend the money to go to a dealer to have it checked out? Lord knows i couldnt afford their repair fees. But do i need to pay for the diagnosis?
Here is another thing, when i bought the car 4 years ago it had 60,000 miles. The day after buying it "brakes" came on. So i took it back to the used car dealer and they either sent it out to be rebuilt or replaced the ABS module. I don't remember what. But it fixed it. I know it had to do the with ABS control. Could it be the module again? Would it cause everything else to fail? I have never seen this problem until recently.
Also, i replaced the tranny filter and fluid for the first time about a month ago. Everything has been great concerned with the transmission since. Is the trans error a result of the ABS system taking everything else down?
Sorry for the book. But i hope it helps. Thanks so much to everyone for their feedback.
*Also, I don't know if it matter but maybe a month ago i took it into the dealer for the ETM software update. I have never had any ETM problems but figured the update was needed what with the recall and all. I hope that hasn't screwed up the system.
