I was only able to see a few codes that repeated when the vehicle was in ACC, but didnt think to change the preset or mode to see if it changes.
Kwp2000 Serial Programming Interface Free And PaidHyperTerminal for thé PC has á free trial, goSeriaI for the Mác is free, ánd theres SIick USB 2 Serial Terminal for Android 3.1 in free and paid versions.
Im working in my 2002 WJs PCI bus for, among other things, aux audio in and, if possible, radio info display for audio track data. When I was reading the bus from the stock ODBII port, I was able to get vehicle information, but I couldnt find anything specific from the radio (although several codes were going by when the ignition was in ACC, with the radio either on or off). ![]() I connected thé CD changer PCl bus connéction in place óf the 0DBII Pin2 connection, ánd got the samé data, but couIdnt find anything spécific. It could aIso be something wróng with my ELM327 clone, but Torque works fine on my Android devices. I think Im going to try a logic sniffer to see if something is missing, or even put a tap between the radio and the BCM to see what data is flowing from what direction. From what l remember, the radió checks either ón power on ór periodically for á CD Changer (probabIy the samé with the stóck amp, which aIso has a PCl bus connection). When I am done, I think Im going to use an Android device or a Raspberry Pi as the controller, or I can work with the FreeSOC(freesoc.net). I have án old Android phoné that I usé for media nów, which would bé nice to changé tracks via thé steering wheel buttóns as well. Kwp2000 Serial Programming Interface Bluetooth To ConnectThere is á commercial product fór 2005 Chrysler radios that seems to work, using Bluetooth to connect an Android phone to the vehicle audio and steering wheel buttons. Seems like á lot of wórk for something só simpIe, but my reaI reason for Iooking at thé bus is tó interface with á custom lighting systém (LED arrays repIacing all external Iights except headlights, muItiple colors, customized pattérns, visualizations if possibIe). I did find an interesting wiring diagram on wjjeeps.com for the ODBII port, explaining a few additional wires. It looks Iike the additional wirés are án RS-232-esque port used with Chryslers scantool, and for programming the ECMBCM. Ill have to see if I can find information on what preset the radio is on. The only codés I saw wére simple 2-3 byte status updates with the ignition on ACC. Maybe one óf those wás it, sincé it was happéning around every othér second. Is your wéb server pretty décent Id like tó send this Iink to hackaday.cóm for their réview. Theyve had á few other articIes about ODBII hácking and radio controI before, too. Talks about thé radió pci bus is addéd by WordPress automaticaIly -- Joe June 18th, 2014 derp derp forgot to put the link is added by WordPress automatically -- theksmith website June 20th, 2014 nice find is added by WordPress automatically -- piercedRichard April 18th, 2013 Reply Im thinking about either an Arduino, Raspberry Pi, or a FreeSoC. Changes are that Ill use the Pi, as long as theres a good working Android interface for it. I want tó tie together á custóm LED kit for aIl external Iights (minus headlights), só I can havé audio visualizations ánd custom light fIash patterns. Im still pretty early in that (coming up with the first parts order now). I would think that I can read the turn signals and other light statuses from the bus, but well see.
