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 ES 300h 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.
The 2.5-litre petrol engine works with electric motors and an electronically controlled hybrid transmission, driving the front wheels on India-market ES 300h cars. This hybrid e-CVT should not be described as an ordinary belt-type CVT or given a generic clutch-replacement package. The ES 300h is also different from the new-generation ES 350h and the fully electric ES 500e. A newer ES photograph or parts listing should never substitute for the actual car's identification.
For poor running, use the driver's account and available diagnostic information to separate an engine concern from a hybrid warning. Spark plugs, ignition coils, injectors, intake leaks and engine mounts require different checks. Overheating investigation considers coolant loss, radiator condition, hoses, thermostat, cooling fan and water-pump operation before recommending replacement. Do not continue driving after an overheating warning or repeatedly top up an unexplained leak.
The traction battery stores energy for propulsion, the inverter manages electrical power and the low-voltage battery supplies other vehicle systems. None of those functions makes a hybrid battery opening a routine service item. High-voltage diagnosis, traction-battery work, inverter repairs and specialist transmission work require separately confirmed training, equipment and safe procedures. This guide does not advertise those services as universally available. A warning message should be recorded accurately and assessed before codes are erased or components are disturbed.
Headlamp damage involves more than the outer lens. Check the housing, mounting points, connectors, water sealing and applicable electronic functions. The correct lamp depends on the generation and fitted equipment. A radiator or AC condenser behind the bumper should be checked for displaced supports, leaks or contact damage. The radiator manages engine cooling and the condenser belongs to the air-conditioning circuit; replacing one does not automatically solve damage to the other.
Windshield replacement must match the vehicle's glass specification and any camera, sensor or mounting requirements. After a relevant glass, bumper or structural repair, safety equipment may require inspection and calibration under the applicable Lexus procedure. Clearing a warning light is not evidence that a safety system is correctly aligned. Required specialist services and their availability should be stated in the estimate before authorization.
A glass claim still needs the policy, event details and the insurer's required assessment. Ordinary deterioration, a faulty previous installation or unrelated wear is not automatically accident-covered. Describe the damaged glass, mouldings and any required system checks transparently, and obtain approval for the proposed repair scope. A required calibration can be included for assessment, but insurer payment is not promised merely because the item is necessary for a repair.
