Failure Inspection

Diagnosis with diagnostic tool

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

    The diagnostic system (diagnostic tool) provides the following information.

(1) Fault Code Searching : Checking failure and code number (DTC)

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

(3) Actuation test: Checking the system operation condition

(4) S/W Management: Controlling other features including system option setting and zero point adjustment

  1. If diagnose the vehicle by diagnostic tool, select "DTC Analysis" and "Vehicle".

  1. Select the 'Data Analysis'.

  1. Select the 'PTG' to search the current state of the input/output data.

Mode Change (Power Tailgate System)

Mode Change (Power Tailgate System)

  1. After replacing with a new power tailgate module, check for DTC code at all times.

    If DTC code B24B0 exists, perform power tailgate mode change.

  2. After connecting the diagnostic tool. Select the 'S/W Management' and 'Car model'.

  1. Select the "Power Tailgate" and Power Tailgate Mode Configuration" procedure.

  1. Perform the "Power Tailgate Mode Configuration" procedure according to the diagnostic tool screen message.

System Initialization

System initialization is needed to recognize the closing position of the tailgate to power tailgate module.

The initialization process after battery power reset, system initialization is needed to recognize the maximum opening and closing tailgate position exactly.

The power tailgate operates normally after system initialization is completed.

Procedure :Inspection and Test - Power Tailgate System

Inspection and Test - Power Tailgate System

Power Tailgate system is a complex system that consists of several components. To get an accurate test result, the control module of the Power Tailgate must be inspected.

The most trustworthy, effective and accurate method is using diagnostic tool required by power tailgate.

diagnostic tool helps technicians when inspecting a disabled switch, and enables to check the current status record of the switch ofPower Tailgate control module.

The battery must be fully charged before conducting all of the test on power tailgate, and all of the interfering elements of the system must be shown and understood, (refer to the explanation of smart tailgate) Refer to the analysis reference table when inspecting and testing the smart tailgate.
