Im awaiting for my cable to arrive (tomorrow) and will be verified then.

The other day i was swapping the infotainment out for my Pioneer unit with the connect2 infoadapter, everything was going to plan until the epb warning light came on.
I forgot to connect the park cable (green) to the pioneer unit.

I have the fault code :-

32837 - Lamp in Switch for Electronic Parking Brake
C1145 13 [009] - Open Circuit

Have I blown the lamp in the parking brake switch? I connected the 2 cables together after the warning light came on.

Do I need to get a new switch or can i get a replacement lamp, will i need to disconnect the battery first before i do this work?

Is this the correct diagnosis?

Thanks in advance
