[QUOTE="Tob, post: 10851654, member: 83412"] Here is a basic introduction to the OBD communication protocol according to ISO 15031: Mode 01 is used to identify what powertrain information is available to the scan tool. Mode 02 displays Freeze Frame data. Mode 03 lists the emission-related "confirmed" diagnostic trouble codes stored. It displays exact numeric, 4 digit codes identifying the faults. Mode 04 is used to clear emission-related diagnostic information. This includes clearing the stored pending/confirmed DTCs and Freeze Frame data. Mode 05 displays the oxygen sensor monitor screen and the test results gathered about the oxygen sensor. There are ten numbers available for diagnostics: - 01 Rich-to-Lean O2 sensor threshold voltage - 02 Lean-to-Rich O2 sensor threshold voltage - 03 Low sensor voltage threshold for switch time measurement - 04 High sensor voltage threshold for switch time measurement - 05 Rich-to-Lean switch time in ms - 06 Lean-to Rich switch time in ms - 07 Minimum voltage for test - 08 Maximum voltage for test - 09 Time between voltage transitions in ms [b]Mode 06 is a Request for On-Board Monitoring Test Results for Continuously and Non-Continuously Monitored System. There are typically a minimum value, a maximum value, and a current value for each non-continuous monitor.[/b] Mode 07 is a Request for emission-related diagnostic trouble codes detected during current or last completed driving cycle. It enables the external test equipment to obtain "pending" diagnostic trouble codes detected during current or last completed driving cycle for emission-related components/systems. This is used by service technicians after a vehicle repair, and after clearing diagnostic information to see test results after a single driving cycle to determine if the repair has fixed the problem. Mode 08 could enable the off-board test device to control the operation of an on-board system, test, or component. [b]Mode 09 is used to retrieve vehicle information. Among others, the following information is available: VIN (Vehicle Identification Number): Vehicle ID CALID (Calibration Identification): ID for the software installed on the ECU CVN (Calibration Verification Number): Number used to verify the integrity of the vehicle software. The manufacturer is responsible for determining the method of calculating CVN(s), e.g. using checksum. In-use performance counters Gasoline engine : Catalyst, Primary oxygen sensor, Evaporating system, EGR system, VVT system, Secondary air system, and Secondary oxygen sensor Diesel engine : NMHC catalyst, NOx reduction catalyst, NOx adsborber Particulate matter filter, Exhaust gas sensor, EGR system, VVT system, Boost pressure control, Fuel system.[/b] Mode 0A lists emission-related "permanent" diagnostic trouble codes stored. As per CARB, any diagnostic trouble codes that is commanding MIL on and stored into non-volatile memory shall be logged as a permanent fault code.
