It seemed to me the fuse getting no power pointed to something physical rather than software glitch. ...back to modifying my cupholder... Agreed. I figured it was physical, but struggled with whether it was an issue inside a module or with wiring. So glad it's over now, maybe I should check my cuph...

Copy/paste from a different forum update, but wanted to make sure it was documented here as well in case someone else can learn something... I'm beyond excited to report that I was able to locate the source of the issue over the weekend! I decided to go back and re-test the CANBUS circuits again, an...

Could it be the CEM has lost the key programming and it doesn't recognize the key chip ? How does the AWD module DEM look like ? Any significant corrosion ? Read at the bottom of the page https://xemodex.com/us/product/differential-electronic-module-for-volvo-vo-1040-86001749-10-20/ I’m pretty posi...

Thought I’d give an update and see if anyone has further ideas. I’ve been troubleshooting slowly but surely over email with Xemodex. We discovered today that the ECM is not getting any power. I tested fuse 12 (for the ECM) in the fuse box with the ignition on, but it also showed no voltage and the f...

It’s been another week and I’ve made no progress. I did verify that there is no fuel being pumped at all, but I’m not sure if that is due to the immobilizer. Does anyone know if the fuel pump should still prime? I was under the impression that the immobilizer cuts fuel to the rail, but that the pump...

It looks like a main harness fault. you could try driving around with vida running to monitor the system real time. when I had ecm faults all over the car it turned out to be the cooling fan for the ecm box, problem was the fuse . Unfortunately I can’t get the car to start. Starter motor engages, b...

So last night I re-installed my CEM and ECM. I also checked the suspension, coils, and everything I could find in the engine bay for corrosion or frayed wires. I opened the casing along the back of the engine bay to examine the wiring going to the ECM. Checked all the grounds I could find. I could n...

you would not go far wrong putting vida on it . It should show when and where any codes are set, under what conditions. drivetrain is no longer original, its above my security clearance. Thanks. The VIDA codes are posted above in my first response. I’m going to clear them tonight, try to start agai...

How did it all started ? There's so many possibilities. See above, may also want to look at the DEM and PEM for corrosion Here is the backstory, copied from another forum post: In short, I have a 2006 V70R that was swapped to an M66 by the previous owner. After purchasing, I had Hilton Tuning progr...

Hi, sorry to dig up an old post, but I’m having this same issue in my 2006 V70R with a manual transmission. I have replaced the immobilizer antenna with a new one. All my connections look fine. I haven’t found any signs of corrosion or fraying. I have sent my CEM and ECM to Xemodex, who could not fi...
