I need any information about the diagnostic interface of OPEL car's... I need to design a clone, of Tech-2, or Tech-1 diagnostic interface, for my own purposes. Can someone help me? Any interface schematic, or PC software can help me too..
Texas instruments (with TMS470) and Freescale (with HC12 series) had built in Class 2 Interface (J1850 VPW) machines into your processors. If you need some help about any OBD2 interface: J1850VPW, J1850PWM, KWP2000, ISO9141-2 and CAN, or interface in TRUCKS SAE J1587/1708, because I work with this protocols.
This protocol don't have standards and is very old, I don't have much information about this.
Will u plz help me with OBD II protocols used in Toyota corralla, Honda and suzuki cars. I have searched the net but it seems that useful free data does not exist. I will require the specification/ possible application notes of the protocols used in these systems. I will be much grateful......
