If the car has LED headlamps, there are modules on the headlamp units to drive the LEDs, and the adaptive functions. The modules are not ECUs in the car loaded with software, they are just hardware controlled by the CEM through LIN bus communications.
It looks like the HCM was introduce to the SPA for 2017 MY on the LED headlamp equipped models.
Hi, i sent a PM to you asking for help on this,
I have a 2016 UK model XC90 Inscription which i have brought to Spain and we want to keep it, but to meet the Spanish law for registering it legally, the beam pattern requires adjustment and on the car this is not possible, took it to a Volvo dealer in Spain and they stated the headlights require replacing, they gave me the equivilent model numbers and managed to source them used from Poland.
Swapped the modules over from the UK lights etc but when turning the car on it has a list of errors, mainly the daytime running lights no longer work and both front indicators do not work, have downloaded Orbit and these are the errors below:
CEM-B11D013 - DayTime Running Light Left (DRL)- General Electrical Failures- Circuit open
CEM-B11DC13 - DayTime Running Light Right (DRL)- General Electrical Failures- Circuit open
CEM-B123A12 - Left Front Turn Indicator- General Electrical Failures- Circuit short to battery
CEM-B123A13 - Left Front Turn Indicator- General Electrical Failures- Circuit open
CEM-B123B12 - Right Front Turn Indicator- General Electrical Failures- Circuit short to battery
CEM-U100D87 - TPMS Information From HMI / DIM- Bus Signal / Message Failures- Missing message
Any help and suggestions would be highly appreciated.
Thank you.
