1. No Power, Charging Failures, and Battery Issues

On-Site Symptoms: The equipment may fail to power on or experience intermittent power issues, fail to charge when connected to the charging cradle, or exhibit faults, damage, or looseness at the AC/DC charging adapter connection (DC jack). Other symptoms include a faulty rechargeable battery, heat at the left-side 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 cradle, visually inspect the charging terminals that connect to the cradle for recessed or displaced contacts and foreign material that could cause poor electrical contact.
2. Check Battery Installation and Test with a Spare Battery: Verify that the battery and battery cover are securely attached. 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: Inspect the AC/DC charging adapter and DC jack connection for damage or looseness. The left-side terminal may generate heat within its normal operating range during charging. Distinguish this normal heating from severe battery overheating.

When to Request Repair Service:

• Power issues persist even with a known-good spare battery installed. (The internal charging board, battery connector board, or mainboard requires inspection or replacement.)
• The charging cradle connection terminals are recessed, displaced, or damaged, or the charging adapter connection (DC jack) is faulty or damaged.
• The battery severely overheats, or abnormal operation caused by excessive current input is suspected. (If the equipment is sent for repair for a condition that is not a defect, such as normal heat at the left-side terminal during charging, and no fault is found, inspection and shipping fees may apply.)

2. Boot Failures, Impact-Induced Shutdowns, and Program Errors

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

On-Site Checks Before Requesting Repair:

1. Restart the Equipment and Check Whether the Error Recurs: If a temporary slowdown or error message occurs, shut down and restart the equipment. Check whether Low Memory Warning or System Coding Error VCI INIT ERROR appears repeatedly.
2. Check Battery Retention for Impact-Induced Shutdowns: If the equipment shuts down when subjected to impact, first check that the battery cover and battery are securely attached without movement. If impact-induced shutdowns continue despite secure battery retention, submit a repair request for internal component inspection.

When to Request Repair Service:

• 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. (Corrupted internal firmware requires reprogramming or recovery, or the VCI board requires inspection or replacement.)
• Boot failures persist after power-on, or impact-induced shutdowns recur. (The internal MCP board, CPU, SSD storage, VCI board connector, or barcode module requires inspection and replacement.)

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

On-Site Symptoms: The display malfunctions or exhibits intermittent visual noise or abnormal colors. Other symptoms include a cracked LCD, touchscreen malfunction, localized impact or indentation damage to the screen, 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 Recognized: During on-site testing, an apparent failure to recognize 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 localized impact marks, indentations, or other damage. If display faults, touch input failures, or indentation damage are identified, submit an official repair service request for LCD module replacement.
3. Check Physical Button Operation: If button presses are not registered 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:

• The display malfunctions or exhibits intermittent visual noise or abnormal colors. (LCD module replacement is required.)
• Touchscreen input failure, screen indentation damage, or breakage is confirmed. (LCD module replacement is required.)
• Input failures persist for 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. Occasionally, abnormal behavior may occur in which the equipment automatically reads a VIN even though the DLC cable is not connected to a vehicle. Other symptoms include wireless network (WLAN / LAN) connection failures 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 failures can be caused by a faulty external DLC cable as well as 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 isolate a cable fault from an internal VCI board fault.
2. Also Check Vehicle Communication (VCI) When a Wireless Connection Issue Is Suspected: Some cases initially identified on-site as wireless connection recognition failures are actually caused by vehicle communication (VCI board) or DLC faults. In addition to checking wireless network signal conditions, verify wired vehicle communication and confirm that the VCI self-test passes.

When to Request Repair Service:

• Vehicle communication remains unavailable 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. (The internal integrated VCI board requires inspection, replacement, or corrosion-removal cleaning. If a cable fault is suspected, include the DLC cable currently in use when shipping the equipment for repair.)
• Network (WLAN / LAN) connection failures with NG displayed, intermittent disconnections, or BA Tool Pairing Failure persist even under normal wireless network conditions. (The wireless module and antenna require inspection or replacement.)

Quick Reference Table

Symptom Category	On-Site Checks Before Requesting Repair	When to Request Repair Service
Power issues / Cradle or adapter charging failures / Severe battery overheating	Visually inspect cradle connection terminals for recessed or displaced contacts and foreign material; check battery and battery cover attachment; test with a known-good spare battery; check the DC jack for looseness.	Power issues persist with a spare battery, or charging terminals or the DC jack are faulty or damaged. If the battery severely overheats, immediately disconnect charging connections and remove the battery, then arrange repair.
Boot failures / Impact-induced shutdowns / Low Memory Warning / VCI INIT ERROR	Restart the equipment and check whether the same error recurs. For impact-induced shutdowns, check that the battery and battery cover are securely attached.	Low Memory Warning, VCI INIT ERROR, or slow performance persists after restarting (recovery or firmware reprogramming required), or boot failures and impact-induced shutdowns recur.
Display faults or visual noise / Touch input failures or screen indentations / Green button or power button failures	If the vehicle VIN cannot be recognized, touch other screen areas to determine whether touch input is unresponsive. Check for surface indentations and inspect physical button operation.	Display abnormalities, touch input failures, or indentation damage are confirmed (LCD module replacement required), or physical button failures persist (keypad board or button replacement required).
Vehicle communication failures (High-Speed CAN (CAN-High) Communication Failure, Test NG) / Wireless LAN failures (NG) / BA Tool Pairing Failure	Inspect the external DLC cable and test with a known-good spare DLC cable. Check both wireless signal conditions and VCI self-test results.	Communication failures or Test NG persist with a spare cable (VCI board inspection or replacement required), or wireless connection failures or disconnections persist (wireless module or antenna replacement required).
Damage to the battery cover / Damper or damper holder / Housing / DLC cover / Equipment support hardware	Visually inspect exterior damage. Do not disassemble the equipment yourself or leave damage unaddressed.	Submit an official repair request promptly when exterior component damage is identified to prevent board corrosion from foreign material ingress and avoid an unrepairable condition.
