KIA Niro: Relay Box (Passenger Compartment) Repair procedures

Fuse Inspection

  1. Check that the fuse holders are loosely held and that the fuses are securely fixed by the holders.
  2. Check that each fuse circuit has the exact fuse capacity.
  3. Check the fuses for any damage.

Warning

If a fuse is to be replaced, be sure to use a new fuse of the same capacity. Always identify the cause of the blown fuse and completely eliminate the problem before installing a new fuse.

Diagnosis with KDS

  1. In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (KDS).

    The diagnostic system (KDS) provides the following information.

(1) Self diagnosis : Checking failure and code number (DTC)

(2) Current data : Checking the system input/output data state

(3) Actuation test : Checking the system operation condition

(4) Additional function : Controlling other features including system option setting and zero point adjustment

  1. Select the 'Car model' and the 'Smart Junction Block (SJB)' to be checked in order to check the vehicle with the tester.
  2. Select the 'Current Data' menu to search the current state of the input/output data.
  3. To forcibly actuate the input value of the module to be checked, select option 'Actuation Test'
  4. If you want to change user option, select "user option".
