Hi all just want to ask if someone have similar issue

On my A-Class randomly show this DTC in HVAC AC memory

Climate (Climate control - HVAC246 (Climate control ) - MT/AT)
DTC Description
A17E - LIN bus power supply
  • Open circuit
  • Intermittent


No effect to work AC working fine all time in Auto / Eco mode

Google doesnt give much about this DTC

Just wondering if anyone of you had any issue with HVAC module?
