Diagnosis using KDS

1. 1

   In the body electrical system, faults can be quickly diagnosed using the Korean Diagnostic System (KDS).

   The Diagnostic System (KDS) provides the following information.

   1. Self-Diagnosis: Checks malfunction and Diagnostic Trouble Code (DTC)

   2. Current Data: Check the system input/output status.

   3. Actuation Test: Check the system operating status

   4. Additional function: Control of other functions, including the setting parameter system and zero point adjustment.

2. 2

   Select "Vehicle Model" and "IBU-BCM" to check, to check the vehicle with the tester.

   • Standard: BCM-MFSW

   • R-MDPS : BCM - MFSW (DN8)

3. 3

   Select the "Current Data" menu to view the current input/output data status.

4. 4

   To forcibly activate the input value of the module under test, select the "Activation Test" option.
