A basic introduction to Canbus technology is https://www.csselectronics.com/screen/p ... anguage/en.

thank you xheart I looked and don't see hose issue but my problem seems to be no voltage at fuse 7 at all also no voltage at a bunch of the fuses in that line. I am considering weather this is just a problem with the fuse block because even with ignition on there is no power in most of the fuses on...

Electronics have made vehicles more powerful (variable cam timing as an example), cleaner (continuous fuel ratio adjustments), more efficient (again continuous fuel adjustments), and much safer (antilock brakes, air bags, and stability control). They have also made vehicles more expensive, harder to...

I do worry about the anthro part of safety engineering. They do worry about this in flight, where it has gotten so safe that pilots literally do fall asleep in flight.

There is no substitute for high situational awareness while driving.

CAN-bus is awesome and is a major improvement over inches thick wiring harnesses. Usually when you have a failure, it is a failure in the remaining analog parts - it is the analog sensor or its wiring. However, digital counterpart is usually able to diagnose it and raise a red flag, which you can re...

This makes a lot of sense. I guess I didn't really look at CAN-bus as being a good thing, but from what I've read about it, plus what you just said, I'm beginning to come around to liking it. 4 wires between the different modules for communication is a lot better than everything needed to be cross ...

The terminology might be confusing. 1. Volvo has 2 CAN-buses, one is "high-speed" and another one is "low-speed". You see them referenced as CAN-H and CAN-L sometime. 2. CAN uses a differential signalling, which consists of two signals known as "high" and "low"...

CAN-bus has 2 wires: high and low. Wikipedia has a pretty good article: https://en.wikipedia.org/wiki/CAN_bus CAN is a very smart solution invented for the automotive needs that solved way more existing problems than created new ones ;) In Volvo some modules are connected to one CAN-bus, while other...

Like the horrible glue they used on the interior door panels? I still haven't found an adhesive that'll hold them together right yet. I don't know if the green stuff needs to be scraped off first, or if I need a stronger adhesive. Tips for door panel attachment: After trying several adhesives, I ha...

I actually used Pliobond brand contact cement. Any brand will likely work.
