Daniel, a year before I'm found this: DRBIII SoftscanIt's a DRBIII sofware scanner, maybe can help you

я хочу на приборную панель отправлять пакеты данных от00 до ff,чтобы понять какой покет за что отвечает You can do that in the GUI with the repeated message feature. There's an option to repeat a message list. You can enter comma-separated messages like this: Unfortunately you have to compile the message list by hand. Automatic ID-byte increment doesn't work for CCD-bus for now. Make sure to try different message lengths to know which length is accepted by your dashboard. In the list at least 2 message has to be present. If you want to try 1 message at the time use the "repeated message(s)" mode with iteration set to "false". Thanks, good luck with your project! He's using an Arduino Mega + CDP68HC68S1E CCD-bus chip (made by Intersil, you can order it from eBay). He's communicating with another CCD-bus chip made by Philips. My scanner is basically the same thing but I placed every component on a single PCB. If you follow my schematic then the GUI I wrote will be compatible. Nevertheless you can easily write your own custom software. Edit: thanks for the info! We use the DRB3 emulator's database in a database-reader application to extract CCD/SCI-bus messages. Someone else wrote this database reader, you can download the compiled executable with database from the pinned blog post.

Привет огромное спасибо за ваш труд,я собрал ваш адаптер на arduino mega 2560 и CDP68HC68S1 но ардуина не видит CCD bus и нет генерации CLK

Which sketch do you use on the Arduino Mega? The ChryslerCCDSCIScanner firmware or one of the CCDBusTransceiver example?

Hi all!I'm also interested in this scanner. My car Chrysler LHS 1994 with CCD. Now im work with Microcontroller ATMEGA2560.

Hello Daniel, I recently bought your fantastic OBD1 scanner for chrysler (I have a 1995 Jeep cherokee XJ with OBD1), I have it connected to the SCI-bus port where I can read the errors of the computer in the software (USB) but I can not do that The LCD screen shows me some data about the engine, everything appears inactive, what should I do so that it shows me the live data on the screen. Tks

Hi, sorry for the timeout, I didn't get notification from the forum (although I enabled it recently...).
Did you change the data source to PCM on the LCD tab in the GUI? Another thing is that SCI-bus needs request messages to provide live data:
14 01,14 05,14 0A,14 0B,14 11,14 24,14 41,14 46
These are the ones displayed on a 20x4 LCD. So it's currently kind of bothersome but you first need to insert this line in the GUI to the SCI-bus combobox, add to the message list, check repeated messages checkbox, enter repeat interval of 50 ms or somewhat shorter, and click on the send message(s) button. Then LCD will display live data.

I sent a message on the website before I realized there was a forum. Would there be an easy way to receive and translate gauge cluster warning light signals from the ccd bus? Either using components from the original panel or using the device for sale on tindie.com? I'm not good with circuitry or assembly language (I know very little about either). What looks like the main control chip in my cluster panel is labeled as SC440726CP 95 Chrysler 3D54HCTCTAU9638 MMMMMMM======= It also has an Ⓜ and © I'd guess it's the standard "copyrighted" C, and the M looks like the Motorola M, so the chip is probably made by Motorola. Idk if that's relevant, but as it doesn't match the CDP68HC68S1 chip being talked about here, idk that it can actually be used (if it's a different chip which hasn't been reverse engineered, the pinout and functions of the chip are presumably unknown to anyone but Chrysler, right? And that's assuming that Chrysler is keeping a thorough record of outdated technology).

The Motorola IC is the main microcontroller. It's not useful for getting around the bus. Look for a Philips chip with 20 lead, that's the CCD-bus transceiver. Example, Body Control Module: It's supposed to be pin compatible with the CDP68HC68S1M SMD-version. This is well documented, so there's no difficulty interfacing it: CDP68HC68S1But it's not easy to build this either way you look at it. To begin with you'll need to write code for an Arduino Mega board that filters CCD-bus messages and somehow controls the lights.
