Data byte B displays all the sub-systems which are monitored continuously, i.e. at least twice per second.
Bit 0 Misfire detection
Bit 1 Fuel system
Bit 2 Other components
Bit 3 Not used
Bit 4 Not used
Bit 5 Not used
Bit 6 Not used
Bit 7 Not used

Data D:
In data byte D, the readiness codes of the sub-systems from data byte C are displayed.
Bits 0 to 7
0 - Sub-system check completed or sub-system not installed.
1 - Sub-system check not yet complete.
NOTE:
- After the fault memory has been erased, the bits of the installed sub-systems are set to 1.
- The bits are reset to 0:
- in the case of a fault-free check after 1 driving cycle
- in the case of a detected fault after 2 driving cycles
