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 Harrier EV 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.
A service estimate should list inspection findings separately from scheduled consumables or replacements. If a concern cannot be reproduced safely, agree what further diagnosis is required. Do not repeatedly drive an unstable vehicle or reconnect charging equipment merely to produce evidence of a warning.
Routine combustion-engine parts such as engine oil filters, diesel injectors, glow plugs, an alternator or a conventional manual clutch do not become Harrier EV service items. The auxiliary 12-volt battery and low-voltage equipment are different from the traction battery and its power system. Lighting, wipers, switches and appropriate low-voltage wiring can be discussed within the confirmed workshop scope.
The fitted motor arrangement, reduction drive, power electronics and charging hardware require configuration-specific identification. Ask CarTech Hub which diagnosis it can accept and where qualified EV or manufacturer-supported involvement is needed; battery opening or high-voltage repair should not be assumed from a scanning enquiry.
Restricted airflow and an electric-compressor or thermal-management fault involve different checks. CarTech Hub should identify the actual cooling arrangement and the accepted scope; work involving high-voltage connections or the electric compressor requires suitable trained personnel rather than an ordinary AC-service assumption.
Body-part enquiries can include the correct front or rear bumper, bonnet, doors, quarter panels, tailgate, grille or trim, lamps, mirrors and windshield. Equipment-dependent fittings, cameras and sensors must retain the specified functions and any required calibration. Denting and painting should follow the decision on mounts and panel condition, with repair, replacement, surface preparation and blending itemised.
If the impact reaches a battery enclosure or high-voltage cable route, qualified EV safety assessment must be completed before energising or charging. Keep clear of exposed conductors, unusual heat, smoke or damaged electrical equipment. Seek emergency and trained EV support when appropriate. Recovery must follow the manufacturer's method for the specific vehicle; an owner should not attempt isolation or internal battery inspection.
