F-scan2 (M-SCAN2) Troubleshooting and Official Repair (A/S) Service Guide

Overview

This guide provides on-site inspection procedures and repair service (A/S) submission criteria for F-scan2 (M-SCAN2) vehicle diagnostic equipment used in vehicle assembly plants. It covers power, charging and battery faults; boot and software errors; display (LCD), touchscreen and button faults; vehicle communication (VCI) and wireless network (WLAN) connection failures; and physical damage.

It distinguishes between checks that on-site personnel can perform on external terminals, batteries and connection cables before requesting repair, and conditions that require inspection at an official repair centre.

Applicable Equipment:

• Applicable Models: F-scan2 / M-SCAN2 (Kia vehicle assembly plant set and Main Module)
• Primary Serial Number (S/N) Format: Includes serial numbers beginning with PM2

If symptoms persist after on-site checks and hardware inspection or component replacement is required, submit a repair request in accordance with the official Inquiry about Product Repair and After-Sales Service Costs guide and the official repair service (A/S) procedure at the end of this article.

1. Failure to Power On, Charging Faults and Battery Issues

On-Site Symptoms: The equipment may fail to power on or exhibit intermittent power faults, fail to charge when connected to the charging cradle, or have a faulty, damaged or loose AC/DC charging adapter connection (DC jack). Other symptoms include a faulty rechargeable battery, heat at the left-hand terminal during charging, or severe battery overheating.

On-Site Checks Before Requesting Repair:

1. Inspect the Charging Cradle Connection Terminals: If the equipment does not charge when connected to the charging cradle, visually inspect the charging terminals that connect to the cradle for terminals pushed out of position or poor contact caused by foreign matter.
2. Check Battery Installation and Test with a Spare Battery: Check that the battery and battery cover are securely fitted. If a known-good spare battery is available, install it and compare whether the equipment powers on normally.
3. Check the Charging Adapter Connection (DC Jack) for Looseness and Assess Heat Levels: Inspect the AC/DC charging adapter and DC jack connection for damage or looseness. The left-hand terminal area may generate heat within the normal operating range during charging. Distinguish this from severe battery overheating.

When to Request Repair Service (A/S):

• Power faults persist even with a known-good spare battery installed (inspection or replacement of the internal charging board, battery connector board or mainboard is required).
• The charging cradle connection terminals are pushed out of position or damaged, or the charging adapter connection (DC jack) is faulty or damaged.
• The battery severely overheats, or abnormal operation caused by excessive input current is suspected. (However, inspection and shipping charges may apply if the equipment is sent for repair due to a condition that is not a fault, such as normal operating heat at the left-hand terminal during charging, and no fault is found.)

2. Boot Failures, Shutdown on Impact and Software Errors

On-Site Symptoms: The equipment fails to boot after power-on or shuts down when subjected to impact. Overall performance may also slow down, or the messages Low Memory Warning and System Coding Error VCI INIT ERROR may appear while the software is running.

On-Site Checks Before Requesting Repair:

1. Check Whether the Same Error Recurs After Restarting: If the equipment temporarily responds slowly or displays an error message, shut it down and restart it. Check whether Low Memory Warning or System Coding Error VCI INIT ERROR appears repeatedly.
2. Check Battery Retention if the Equipment Shuts Down on Impact: First check that the battery cover and battery are securely fitted without movement. If shutdown on impact continues despite secure battery retention, submit a repair request for inspection of the internal components.

When to Request Repair Service (A/S):

• The Low Memory Warning pop-up appears repeatedly or overall performance remains slow (system recovery and software reinstallation are required).
• The message System Coding Error VCI INIT ERROR continues to appear after restarting (reprogramming or recovery of corrupted internal firmware, or inspection and replacement of the VCI board, is required).
• Boot failure after power-on persists, or shutdown on impact recurs (inspection and replacement of the internal MCP board, CPU, SSD storage, VCI board connector or barcode module is required).

3. Display (LCD) Faults, Touchscreen Malfunctions and Physical Button Failures

On-Site Symptoms: The display may be faulty or show intermittent visual noise or abnormal colours. Other symptoms include a damaged LCD, a faulty touchscreen, screen indentation damage, or failure of physical buttons on the main unit, such as the green button or power button.

On-Site Checks Before Requesting Repair:

1. Check for Touch Input Failure if the Vehicle VIN Cannot Be Recognised: During on-site testing, an apparent failure to recognise the vehicle VIN during vehicle selection or an Auto VIN search may actually be caused by a touchscreen or LCD fault. First touch other menus or areas of the screen to determine whether touch input itself is unresponsive.
2. Visually Inspect the Screen Surface for Indentations and Damage: Check the screen surface for indentation damage or breakage. If display faults, touch input faults or indentation damage are found, submit an official repair service (A/S) request for LCD module replacement.
3. Check Physical Button Operation: If button inputs are not recognised correctly due to a faulty physical switch, such as the green button or power button, the internal keypad board or button components require inspection.

When to Request Repair Service (A/S):

• The display is faulty or shows intermittent visual noise or abnormal colours (LCD module replacement is required).
• Touch input failure, screen indentation damage or breakage is confirmed (LCD module replacement is required).
• Input faults persist with the green button, power button or other buttons (keypad board or button replacement is required).

4. Vehicle Communication (VCI) Failures, External DLC Cable Faults and Wireless Network (WLAN) Connection Failures

On-Site Symptoms: A DLC connection cannot be established or vehicle diagnostic communication fails, and High-Speed CAN (CAN-High) Communication Failure and Test NG appear during the VCI self-test. Abnormal behaviour may occasionally occur, such as the equipment automatically reading a VIN when the DLC cable is not connected to the vehicle. Other symptoms include wireless network (WLAN / LAN) connection failure with NG displayed, intermittent disconnections, and BA Tool Pairing Failure.

On-Site Checks Before Requesting Repair:

1. Inspect the External DLC Cable and Test with a Spare Cable: Vehicle communication faults may be caused by a faulty external DLC cable rather than an internal fault in the main unit. Inspect the condition and connections of the DLC cable in use, then test with a known-good spare DLC cable to distinguish a cable fault from an internal VCI board fault.
2. Also Check Vehicle Communication (VCI) if a Wireless Connection Detection Fault Is Suspected: Some issues initially identified on-site as wireless connection detection faults are actually vehicle communication (VCI board) or DLC faults. Alongside checking wireless network signal conditions, verify wired vehicle communication and confirm that the VCI self-test passes.

When to Request Repair Service (A/S):

• Vehicle communication still fails after testing with a known-good spare DLC cable, or the VCI self-test displays High-Speed CAN (CAN-High) Communication Failure or Test NG (inspection or replacement of the internal integrated VCI board, or cleaning to remove corrosion, is required; if a cable fault is suspected, include the DLC cable currently in use when sending the equipment for repair).
• Network (WLAN / LAN) connection failure with NG displayed, intermittent disconnections or BA Tool Pairing Failure persists even under normal wireless network conditions (inspection and replacement of the wireless module and wireless antenna is required).

Quick Reference Table

Symptom Category	On-Site Checks Before Requesting Repair	When to Request Repair Service (A/S)
Power faults / Cradle or adapter charging faults / Severe battery overheating	Visually inspect charging cradle connection terminals for displacement and foreign matter; check that the battery and battery cover are securely fitted; test with a known-good spare battery; check the DC jack for looseness.	Power faults persist with a spare battery installed, or charging terminals or the DC jack are faulty or damaged. If severe battery overheating occurs, immediately disconnect the charging connections and remove the battery, then send the equipment for repair.
Boot failure / Shutdown on impact / Low Memory Warning / VCI INIT ERROR	Restart the equipment and check whether the same error messages recur. If shutdown on impact occurs, check that the battery and battery cover are securely retained.	Low Memory Warning, VCI INIT ERROR or slow performance persists after restarting (recovery or firmware reprogramming is required), or boot failure and shutdown on impact recur.
Display faults or visual noise / Touch input failure or screen indentation damage / Green or power button failure	If the vehicle VIN cannot be recognised, touch other screen areas to determine whether touch input is unresponsive. Check for surface indentations and inspect the physical buttons.	Display abnormalities, touch input faults or indentation damage are confirmed (LCD module replacement is required), or physical button faults persist (keypad board or button replacement is required).
Vehicle communication faults (High-Speed CAN (CAN-High) Communication Failure, Test NG) / Wireless LAN faults (NG) / BA Tool Pairing Failure	Visually inspect the external DLC cable and test with a known-good spare DLC cable. Check both wireless signal conditions and the VCI self-test result.	Communication failure or Test NG persists with a spare cable connected (VCI board inspection or replacement is required), or wireless connection failures or disconnections persist (wireless module or antenna replacement is required).
Damage to the battery cover / Damper or damper holder / Housing / DLC cover / Equipment holder	Visually inspect external damage. Do not attempt unauthorised disassembly or leave damaged components unrepaired.	Submit an official repair request promptly when external mechanical component damage is found, to prevent foreign matter ingress from causing board corrosion or rendering the equipment unrepairable.
