More specifically, the C1627 problem is a CAN comm error between the HECU (Hydraulic and Electronic Control Unit) for the brakes and the the ECU on an AWD vehicle. Either one of these units, or the wiring between them, is faulty.

Bad news ... when this happens, you have no ABS or ESC, and that's what is lighting the dash lights. They MUST fix this for you.

Hi,

DTC C1627 is a manufacturer specific code for the chassis, this according to the first letter :
  • B = Body,
  • C = Chassis,
  • P = Powertrain and
  • U = Network.
The 6 stands for some computer output circuit or missing/wrong signal similar to what Canderson wrote about.

You wrote this C1627 doesn't exist on Hyundai's GDS... it could be worth checking on the carbon copy car of Hyundai's subsidiary KIA, i.e. the Kia Sorento :
  • With this DTC C1627, a technical service bulletin (KIA TRA 034) recommends replacing the transfer case motor.
It could be wise to have a special look on this area, connectors and harness going to the transfer case.

BTW, as far as I know directly from Continental Teves and BOSCH, if the ESP light is on or blinking, there is no more ESP, no more ESC or other optional functions (Overroll protection, emergency braking, trailer programm a.s.o.).
The ABS which is the basic function, should still be working !

It's only if the ABS light is ON, alone or with the ESP light, that you only have the brakes working without any electronic helper... like 40 years ago

Anyway, your dealer have to solve and fix this issue a.s.a.p. it's a safety one !

Hope this could help you little bit further on.

Regards
Roland

Actually, the detail I provided came directly from Hyundai, and applies to the CM Santa Fe owned by the OP.

Not a good to try to cross Kia DTCs to a Hyundai. These manufacturer specific codes don't all have the same meaning across these vehicles, similar though some of the components may be.
