Hi there,
First post, hopefully I add all needed info...
It has been really cold around here lately (-20 Celsius). A couple of days ago I was waiting in the car for the kids to come out and tried to enable the preconditioning (parking heater), which had been working without an issue till that moment. Long story short, the parking heater did not turn on, and a message came on in the dash stating that it needed service.
Connected the car and read DTCs, and got the following:
CCM-B15B693 Combustion preheater module CPM. Component Failures. No operation.
CCM-B1D2993 No start, even after restart attempt. Component Failures. No operation.
Also had a message in VDash stating that the battery voltage was low (<12 volt).
After clearing DTCs, CCM-B15B693 will always come back and no parking heater operation.
Reading around about the Webasto units in these cars, it seems that low voltage is one of the conditions to prevent heater start up and repeated attempts to start the heater unsuccessfully will lead to a soft-lock of the heater requiring a reset via VIDA or tapping directly into the Webasto control line and using Webasto's Thermo Test PC application.
So simple question: is VDASH able to perform the reset of the stored errors in the parking heater through CCM functions? If so, does it require a subscription?
As said before, it is -20 Celsius outside and I don't have a closed garage to work in, so I just read the codes and reset DTCs, did not look around the functions available in the CCM (and hadn't read about the code either, to understand what could have cause the issue).
Thanks in advance!
Best regards,
JP
