In cars where diagnostics communication takes place using a gateway, it is possible with this function to quickly get a list over all systems in the car and their current status. Very useful for service work, etc. The following status can be shown:
Shown in the list | Meaning |
---|---|
No fault codes | Control unit participates in data bus communication, no faults are stored in the control unit. |
Fault code stored | Control unit participates in data bus communication, one or several fault codes are stored in the control unit. |
Coded, no communication | Control unit is registered as coded in the car's gateway, but communication is missing. |
Installed, not coded | Control unit participates in the car's communication but is not coded in the car's gateway. |
