System Self-test
The MRS 5 performs a system self-test as from terminal R "ON". The airbag warning lamp is actuated for 3 - 5 s during the system self-test.
When the system self-test is concluded and no fault has been found, the airbag warning lamp goes out and the system is ready for operation.
Fault Output (diagnosis)
With the aid of the diagnostic tools (DIS plus, GT1), the fault code memory can be read out via the diagnosis interface.
After rectifying the faults, the fault code memory can be cleared by means of the "clear fault code memory" diagnosis command.
