Generic OBD
Here you will find information about Generic OBD and explanations of the different icons that you can find in your diagnostic software.
Generic OBD (GOBD) is a software used to read out data from the vehicle’s built-in statutory diagnostic function. The primary function of which is to monitor emission-related components’ function. In Europe this standard function is called eOBD, in the USA it is called OBD2, and in Japan it is called JOBD.
Autocom have decided to collect these standards in one and the same software. It also contains all standards for reading out statutory OBD on heavy vehicles.
Generic OBD is available in two user levels: “Advanced mode” and “User mode”. We highly recommend “User mode” for use in workshops.
The vehicle shall have the ignition on or the engine running to enable connection to all systems.
The first window contains general information about the vehicle.
Available control units – includes all those control units that support the eOBD standard.
Information – specific data for the chosen ECU is shown here. To choose another ECU, click on it in the list with available control units. This box show three different values, such as: MIL status, quantity of fault codes (permanent), as well as which communication standard that is being used.
Main information – show which communication type that the vehicle uses to communicate and the total quantity of fault codes from all control units. This also shows if the MIL is lit.
Readiness tests – show tests for chosen ECU, and if they are supported by the control unit. The different values that can be assumed are done or not done. The following tests are standard in OBD II/eOBD:
-
Misfires
-
Fuel system
-
Component test
-
Catalytic converter
-
Preheated catalytic converter
-
EVAP
-
Secondary air system
-
AC-system
-
Preheated lambda (oxygen) sensor
-
EGR-system
Read fault codes
This lists both permanent and intermittent fault codes from the control units that support the eOBD standard. They are shown with ECU-number, fault code number, as well as a description of the fault code.
Erase fault codes
With this function you can delete fault codes and diagnostic information. This function not only delete fault codes, it also delete the readiness tests as well as “Frozen data”. To perform the readiness tests again, the car has to be run through driving cycles. Some tests are more advanced than other, and therefore take longer time to complete.
Read data from the chosen ECU and from a chosen value. The values are updated continuously.
Graph
A graph of up to three chosen values from the list for current data. Chose the row in the current data list with the value. If a value is wrong, you get a hint informing that the value cannot be. When one to three values are chosen in the list you can press on the tab graph.
Data list
The function consist of three different parts, Values, Current data, and Information. The value list show the real time parameters. The current data list include the chosen values and the information box show information about the values that have additional explanation. To be able to see a value, it must be chosen in the box under the heading values.
Read stored data values belonging to permanent fault codes from different control units.
When the fault code is set, current data is stored in the control unit. A fault code can store up to 255 different lists.
Read out values from the Lambda (oxygen) sensor.
These can be chosen and are then added to the list ”Values”, where they are read continuously. The recycle bin empties the list with values.
These values are read and indicated with TID- and CID-numbers, defined by the vehicle supplier.
The column “Results” indicates if the test has an approved value or a non-approved value. If there are no limit values, then ”—” is shown in the column.
The list ”Tests” include the tests that are available per ECU. The standardised functions are presented with a text, while others are presented with TID-number and the text ”Car specific”. To see a test, click on the test in the list. The test will then be moved to the value list. The recycle bin empties the list with tests.
The “Car information” show three manufacturer-specified values per ECU:
• Chassis number
• Calibration identification number
• Calibration verification number
