>> Diagnostics of All Available Systems

With TOPDON CarPal, you no longer have to wonder what the glowing error light on the dashboard means. It is like a personal doctor for your car! It will give your car a full check-up. You can use the diagnostic information to identify the specific problem areas and make necessary repairs.

• [System Coverage] Engine, Transmission, Airbag, ABS, ESP，TPMS, Immobilizer, Gateway, Steering, Radio, Air Conditioning ... depending on the vehicle’s make/model/year.
• [For Maintenance] Read Diagnostic Trouble Codes (DTCs) in target systems to locate the trouble area precisely; and support clearing all DTCs with a single touch.
• [For Analysis] Monitor the real-time Live Data Stream displayed in diverse modes (text / waveform graph / analog gauge). PIDs are such as Vehicle Speed (km/h), Engine RPM (rpm), Mass Air Flow Rate (g/s), etc.
• [Vehicle Health Score] After every system scanning, CarPal will evaluate how healthy your car’s systems are and give it a score. You can turn this scanning result into a diagnostic report and keep it as vehicle health logs for future analysis.

>> 6 Most-Common Maintenance Services

• Oil Reset, the #1 Service Car Drivers Need in U.K.

Oil reset (oil change reset, or oil life reset) is crucial for car drivers because regular oil changes are essential to maintain a vehicle’s performance and prolong the engine life.

With TOPDON CarPal, you can easily reset the oil change indicator after an oil change or maintenance service; turn off the “check engine” light and the reminder that appears on the dashboard.

By doing this common service on your own, you can only pay for the materials used for the oil change, saving 10~30 bucks around.

• Throttle Adaptation, Calibrate Throttle Control System

Throttle adaptation can relearn the throttle’s operating parameters and restore optimal performance, because over time the throttle system can develop issues like throttle lag, poor acceleration response, or rough idling.

By doing this reset service independently, you may save from 50 to 200 bucks instead of asking for a mechanic’s help.

• EPB Reset (Save 50~150 Bucks)

Struggled to service cars with electronic parking brakes? It can be quite a hassle without a scan tool that helps you retract electric parking brake calipers. With this feature, you can easily reset the brake pad position after replacement.

• BMS Reset (Save 45~250 Bucks)

Notice your car system still treating the new battery like the old one? It’s time to assess the battery charge state and register the replacement. Use this code scanner car diagnostic tool to ensure your new battery gets recognized by your car system.

• TPMS Reset (Save 70~150 Bucks)

Had the tire pressure fault indicator light up on your car? This function can reset the tire pressure and turn off the indicator.

Usually most tire shops will charge you between 70 to 150 bucks for a TPMS replacement per single wheel. But with TOPDON CarPal, if you have the skills to replace the tire yourself, you can save that amount of money.

• DPF Regeneration (Save 100~500 Bucks)

Ever had issues with your DPF system, like excessive soot buildup or perf0rmance issues? This diagnostic scanner is here to save your day. It efficiently manages DPF regeneration by burning captured particulates in the filter, effectively clearing blockages.

>> Check Engine Status with DTCs Analysis

>> Quick I/M Readiness Check: PASS or FAIL

Upon a single touch, TOPDON CarPal will verify your car’s I/M readiness status, and determine if it would pass the state’s annual inspection (also known as emis*ion inspection).

The test results are very clear and easy to understand: a green “PASS” indicates a pass, while a red “FAIL” would be a failure.

If a particular part is not working correctly, CarPal will give it a “Not Ready” mark in red.

>>AutoVIN Rapidly Identify VIN for 2006+ Cars

This advanced car scanner also allows rapidly identifying most cars made after 2006, to get detailed information like “manufacturer, make, model, type, fuel type, engine info, etc.”, then instantly scanning all diagnosable ECUs and executing testing with only one tap.

This will save you much time and effort rather than going through various steps.

 FAQ: Why this function doesn’t work?

• Make sure the car is made after the year 2006.
• Make sure there is a stable network connection.
• AutoVIN recognition isn’t 100% available. You may go with manual input for a precise scan.

>> Accurate Battery Check for 12V Lead-acid

A weak or failing battery could lead to issues with the vehicle’s electrical systems, including the lights, which can compromise safety on the road. So a regular battery check is essential before potential battery issues cause unexpected situations.

TOPDON CarPal has got your back with an accurate battery check:

• Give you real-time voltage readings for reference.
• Track the battery voltage changes in real-time for analysis.
• Record battery startup data: 1) the total startup time; 2) the voltage before, during, and after startup.

• This function works only with cars that have a 12V lead-acid battery.
• To get the most accurate results, run the test when the battery is fully-charged, or wait about 3 minutes after you turn on the engine.
• Turn off the engine before the test.
• If you’re doing several tests in a row, have an interval of at least 3 minutes.
• If you get bad results repeatedly, get a retest done at a repair workshop for confirmation.

>> 0~100km/h Acceleration Car Performance Test

This is one of the most important tests that most similar scan tools don’t offer. With this test, you can measure the time it takes for a vehicle to accelerate from a standstill to 100 kilometers per hour.

This can be used for various purposes:

• To provide a benchmark for the vehicle’s acceleration performance, which is an important aspect of a car’s overall power and speed capabilities.
• To determine which vehicle offers better driving quality by comparing their acceleration times.
• To avoid dangerous situations when overtaking or merging onto highways, with the knowledge of how quickly your car can accelerate.
