The movie version of Bumblebee being a Camaro who can’t talk and has to communicate using the radio is a bit ironic given how removing the radio will completely disable the real car. Remove the radio and the car won’t start, can’t even turn on the lights! Metra has reverse engineered that junk and makes a kit (sans radio) so an aftermarket radio can be installed – and the car can be driven. That’s led to BS like the latest Camaro where the controls for *everything* are integrated into the radio. So now, instead of simply pushing a couple of contacts together in an inexpensive switch, a light “switch” is a Rube Goldberg or Heath Robinson affair of digital electronics that costs a small fortune to replace when it quits working VS being able to carefully take apart a real switch and clean the contacts. Hasn’t reduced the amount of wire in a car either, like was touted back in the 80’s when “multiplexed” systems for car wiring were first bandied about. Using a computer network to do simple tasks like opening windows and switch lights on and off is a bloody stupid overcomplicated thing to do in a car, plus it only serves to make the car cost a lot more. Posted in classic hacks, gps hacks, Transportation Hacks Tagged CAN, GMLAN, gps, onstar Post navigation To anyone who decides to pick up this project and run with it, let us know! Unfortunately for the project, (and very fortunately for ), he has a child on the way and new job responsibilities, so he is offering up his results to the HaD community to finish up, double check, and provide a good how-to for everyone else. There is sample code available to convert this information into generic latitude and longitude. He has also done most of the software snooping and sleuthing, and has mostly solved GMLAN’s method of announcing GPS data. For the new version, has figured out GM’s Controller Area Network (CAN), which they call GMLAN. Previously, we have covered a way to grab the GPS data from an unused OnStar system, however in recent years GM has added much more complex systems, which make it harder than swapping out a serial line. Replace the speed sensor if there is no voltage reading, voltage reading is not above 3.50vdc, or the voltage reading does not fluctuate as the motor is turned.Has provided us with his new guide to hacking the OnStar GPS. (The voltage reading of 4.85vdc is an approximate reading the actual reading may vary from 4.50vdc to 5.00vdc). The voltage reading will fluctuate from zero to 4.85vdc and back to zero four times for each revolution of the motor armature. As the armature rotates, the voltage reading should alternate from 0vdc to approximately 4.85vdc. Slowly turn the rear wheel to rotate the motor armature. With a DVM, place the black (–) probe on the battery main pack Negative post and place the red (+) probe on the green wire between the 3-pin connector and the motor speed sensor. If there is still a problem after the solenoid and if the speed sensor checks out, we can go deeper. I will post a meter check for you below to test the speed sensor. I would replace the solenoid and see what happens. The speed sensor sounds "iffy", but it will beep in both Fwd and Rev. That indicates a welded solenoid and will put you in limp (1/2 speed).
