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 Nano 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.
On a manual Nano, clutch plate, pressure plate and release-related components should be considered only after checking the complaint and compatible assembly. On an automated-manual vehicle, starting and charging condition, fault data and control or adaptation requirements can be relevant to a shift problem. A gear-selection issue is not automatically proof that the whole gearbox is worn out.
Suspension and steering checks can cover struts, arms, bushes, ball joints, tie-rod ends and wheel bearings applicable to the build. Inspect tyre sizes and condition against vehicle information rather than fitting a generic set. For AC-equipped examples, compare airflow, refrigerant-system condition, compressor operation and condenser integrity. Battery, starter, alternator, lighting, earthing and wiring checks help distinguish a poor connection from a major electrical replacement.
Identify whether the Nano has factory CNG equipment or an aftermarket conversion and supply its relevant records. The fitted gas system needs suitable checks, and a gas smell must be reported rather than treated as an ordinary petrol-engine warning or a reason to order a sensor without testing.
A rear collision may involve the powertrain and cooling layout as well as the bumper. Describe the impact and any subsequent temperature or coolant concern, while allowing for front-body checks too; do not open a hot system or repeatedly restart after suspected water ingestion.
The Nano's actual brake hardware must be identified before selecting friction or hydraulic parts. A soft pedal or reduced braking needs safety assessment before further use; assumptions about front disc pads do not establish what is fitted or what caused the complaint.
Testing must support an injector or sensor decision. The investigation should use the Nano's fitted fuel system and engine information, with relevant filtration, ignition, mounts, seals and cooling condition considered according to the symptom rather than replacing a component solely because a warning appeared.
