Tell us which warning light came on and what your car was doing at the time. We’ll confirm which scanner checks your vehicle supports, explain the findings and agree on the next step with you.
Diagnostic information updated 29 October 2026 · Independent multi-brand workshop
Tell us the vehicle’s year of manufacture, variant, engine or fuel type, and the exact warning message. Different versions of the SEAL may have different control units and require different diagnostic access.

This is a model-specific enquiry page. The workshop can confirm which checks your model year and control system support.
CarTech Hub uses LAUNCH Scan Plus X and XTOOL Compass for scanner-assisted fault finding in Sawkuchi, Guwahati. Share your car’s make, model, year, fuel type and warning message so we can confirm the relevant scanner coverage before your visit.
Ask about a Scan Plus X check when reporting a warning light, starting problem or electronic-system concern. We first confirm communication with the relevant control unit and the diagnostic functions available for your vehicle.
The installed software, vehicle year, engine and control unit determine which checks are possible. Code reading, live-data checks and service functions are confirmed for the job before work begins.
LAUNCH official vehicle-coverage resource ↗XTOOL’s Compass information lists fault-code reading and clearing, live data, freeze-frame information, actuator tests and reports from scans before and after work. Availability depends on the vehicle and supported system.
We use the relevant information to investigate your complaint and explain the next check. XTOOL lists Compass and Compass Master configurations separately, so optional hardware and programming access are confirmed for each task.
XTOOL official Compass product information ↗We accept scanning enquiries for Indian, Japanese, Korean, European and other car brands. A brand or model listing does not confirm access to every control unit. The vehicle’s ECU, software version, licence, security access and any required accessories affect the work we can accept.
Ask separately about service resets, adaptations, coding, programming, ADAS calibration or EV high-voltage work. These need the right equipment and procedures; they are not automatically part of a basic scan. A fault code helps direct an investigation and does not by itself prove which part needs replacing.

CarTech Hub first records the warning and the driving conditions in which it appeared. On supported vehicles, the technician reads the engine, ABS or airbag control module and checks whether its fault codes are current or stored. For an engine complaint, freeze-frame data and sensor readings can show the engine’s operating conditions when the fault occurred. For ABS, individual wheel-speed readings can help isolate an inconsistent signal. An airbag warning calls for a restraint-system assessment using the manufacturer’s procedures. The technician explains any further tests and discusses the repair estimate with you before you approve the work.
A fault code is one clue. The technician compares it with the symptoms you describe and the condition of the vehicle before recommending further checks.
Share the vehicle details, warning message, recent work and the conditions in which the issue appears.
We check whether the scanner supports the system you want tested and agree with you on what the initial assessment will cover.
Available codes and data guide further electrical or mechanical checks. A stored code alone does not justify replacing a part.
Discuss what is confirmed, what still needs testing and the estimate before approving further work.
Where appropriate, repeat relevant checks and review the original complaint. Clearing the warning light alone is not a completed diagnosis.
The directory has 765 model entries across 36 brands, including earlier generations and variants. Choose your car and tell us its model year, fuel type, variant and warning message. The workshop will confirm which control units it can check and which repairs it can undertake.

Coverage depends on the model year, control unit, software and access requirements. Tell us the symptoms or warning message so we can check whether the relevant function is supported before you visit.
A code records a condition detected by the car. A technician may need to inspect wiring, power supply, mechanical components or operating conditions before recommending a replacement.
Programming and calibration are separate jobs. Before booking, ask what hardware and software access the work requires, whether a trained technician is available and what the work would cost for your vehicle.
Bring your vehicle details, a description of the symptoms, relevant service records and any earlier scan report. Tell us about recent battery work and whether anyone cleared the fault codes.
For periodic care, assess elapsed time, mileage, previous work and the manufacturer's requirements rather than giving every SEAL the same interval. Record long standing periods, daily short use and a recent wheel impact or monsoon event. Before an outstation journey, review tyre condition, wipers, lighting, brake concerns and low-voltage battery health through supported checks. A routine workshop inspection does not certify battery condition, complete a manufacturer campaign or guarantee that every electronic system is fault-free.
A DC-DC converter supplies the lower-voltage electrical system, and an onboard charger is involved when the car receives suitable AC charging. The external charge point and the vehicle's charging components perform different jobs. These explanations help an owner describe a complaint; they do not establish which assembly has failed. Integrated EV technology also means a symptom may involve more than one system, so unsupported trial replacement or high-voltage disassembly is not a sensible first step.
If a brake or stability warning appears, suitable diagnostic support is needed to interpret it. Wheel-speed information, wiring or other systems may be involved, so replacing pads alone may not address the cause. A significant pedal change, serious pull or damaged wheel warrants a decision about safe transport before a road test. Brake fluid and relevant maintenance tasks should follow the correct vehicle guidance and an accepted workshop procedure.
Wiper blades, cabin filters, interior airflow and suitable low-voltage lighting checks are practical ownership topics. A filter restriction can reduce airflow without establishing an electric compressor failure. AC and thermal systems may contain high-voltage equipment, so supported local checks must stop at the confirmed scope. Parts availability, technical compatibility, price and delivery time are established after identification and supplier confirmation, particularly where an assembly includes model-specific electronics.
The smaller electrical battery supports control and convenience systems; it is not the traction battery. Its chemistry and replacement requirements must be identified for the car. A ready-state or low-voltage warning needs an appropriate assessment, while repeated resets or an unverified battery substitution may obscure the original concern. CarTech Hub can discuss the supported inspection route and direct specialist concerns appropriately.
For charging problems, save the message and identify the charge facility and whether the session was AC or DC. Avoid probing connectors or working around exposed or damaged charging equipment. Cabin cooling concerns, abnormal warnings or suspected underbody damage may require qualified EV support before service proceeds. The owner does not need to identify the inverter, charger or battery as the failed part in order to request useful assistance.
