B7 31 O2M

No valid COx signal from PLL52

CRC fault of a parameter page

Reset the unit

Attention!
If fault occurred during parameterization:
Check the parameters changed last.
If fault cannot be rectified by the reset:
Restore parameters from AZL5.
Otherwise, replace the O2 module

B7 32 O2M

No valid COx signal from PLL52

Page too long open

Reset the unit

Attention!
If fault occurred during parameterization:
Check the parameters changed last.
If fault cannot be rectified by the reset:
Restore parameters from AZL5.
Otherwise, replace the O2 module

B7 33 O2M

No valid COx signal from PLL52

Page disrupted

Reset the unit

Attention!
If fault occurred during parameterization:
Check the parameters changed last.
If fault cannot be rectified by the reset:
Restore parameters from AZL5.
Otherwise, replace the O2 module

B7 34 O2M

No valid COx signal from PLL52

Invalid access to parameters

Reset the unit

Attention!
If fault occurred during parameterization:
Check the parameters changed last.
If fault cannot be rectified by the reset:
Restore parameters from AZL5.
Otherwise, replace the O2 module
