I'm in need of expert help on my XC70. I'm a mechanic and have been for the last 26 years - but old school, where functional understanding, a multi-meter and a good ear could fix anything. Now we're in a world of computers and it's not so easy - for those of us that don't have all of the different proprietary software required!
Anyway, I have a 06 XC70 that i got on the chap as a total punt. If i can get it going i'll be thrilled, but i also understand that it's a potential pile of burning cash so i'm willing to sink another $500 into it to get it running, after that, call the wrecker and send it to the breakers yard. Reason being, it's a total unknown regarding how well it runs, if the transmission is good, if the 4x4 system is good and so on. The rest of the car is exceptionally clean and well kept. At some point, 3 or so owners ago everything worked fine. Apparently. I'm the third person to take on this issue.
"Start Prevented" I know enough about modern vehicles to know they are all coded to the cars themselves. Volvo it seems is a bit more involved having 3 modules to worry about all talking to each other.
I have 2 CEM's, 2 key antenna's, 2 different keys along with ignition barrels. 1 BCM & 1 ECM. They have all been swapped around and the configuration that is in the car now are original. Apparently.
No configuration of the components gets the car started - just the error message that the start has been prevented, and a brake system failure. As this vehicle has been in a game of musical modules, i just need to start again. What are my options beyond towing it to Volvo and bending over the billing counter with my pants down?
Do the antenna rings play any part in the security side or are they simply data transmitters between the key & modules? If the latter, no need to mess with that part.
I'm fairly certain that VIDA is going to be required here, but on the off-chance it isn't, what other software is capable of talking and writing to the modules?
I simply need someone to sync 1 set of modules together. As i only have 1 BCM & ECM, and they are still in place i have to assume they are original. I've read previously that modules have to be cleared in the original car they were placed in before they can be reprogrammed, but this was a long time ago. Is this still the case or can junk yard modules now be programmed?
In digging around i did see that XeMODeX can reprogram, but this comes at a hefty cost. Who else can do this? I can't seem to find definitive purchase options for consumers. i did see a 3 day subscription, but again, that was a long time ago.
It's all really frustrating stuff. Shouldn't matter if the vin's don't match.
Thanks in advance for any input, it's very much appreciated!
