Ranger Mods

Hey team. I’ve got a 2015 PX MK2 XLT (MY16) that has just decided to throw up an orange spanner on the dash (with see manual - that tells me power train fault) I’ve been to the mechanic who services the car and he said it was a code telling him it was due service, which has been done, but he can’t reset it.
I am wondering if anyone in forscan land has experience with this and is able to assist me at all? I’m located in Redcliffe (north of Brisbane) and am desperate to get it sorted! Happy to reimburse anyone who is able to help out for their time.
I’m hoping it’s just a simple reset, but just in case I’d rather someone with more knowledge than me to be playing with it!
Any help is appreciated!

Best I can organise is the Gold Coast. Basically your codes need to be read and it will give you the answer. Find a local auto elect or mechanic with a good scantool is another option and post the DTCs.
