Automobile Diagnosis can be tagged as a strange word some years back in Nigeria. But today almost everyone know that Vehicle Fix are made easier and faster and more precise by Diagnosis. I'll prove with several scenerio I have witnessed:

1. 2005 Volkswagen Touareg that will Crank but not start; the owner was told to replace Engine Control Module (ECM) and Tranmission Control Module (TCM). MechoMedics ran Diagnosis and fixed it with a piece of Wire.

2. 2008 Toyota Sienna 2GR-FE 3.5L V6 Engine fails to start several time and when you Throttle to Start it runs rough with black smoke/carbon soot. MechoMedics Diagnosed and simply dried the Mass Air Flow (MAF) Sensor Connector and erased DTCs. That was all.

3. 2006 Lexus RX330 with Malfunction Indicator Light (MIL) ON and Transmission harsh shift. Would have been told to replace Transmission but MechoMedics ran Diagnosis and fixed a open circuit in a Transmission Intermediate Shaft Speed Sensor.

4. 2014 RAV4 came to MechoMedics with Malfunction Indicator Light (MIL) ON and poor fuel economy, the owner was ready to replace Oxygen Sensor. Our Diagnosis revealed a fault Engine Control Module (ECM) as the Heated Oxygen Sensor (HO2S) and Air Fuel Ratio (A/F) Sensor Tested.

5. 2015 Toyota Highlander 2GR-FE 3.5L V6 Engine had poor Fuel economy with MIL and 'CAUTION', VSC TRAC, 'SLIP' warning Light ON in a dealership franchise. MechoMedics was called and Diagnosis revealed a DTC relating to Heated Oxygen Sensor (HO2S) fault only. We supplied a Sensor with a lower Resistance to this Workshop and the job was a fix to them.

6. 2014 Lexus GX460 that had a slight rear impart with no airbag deployed but had Airbag Warning Light and Restraint Warning Light on due to Occupant Classification System (OCS) fault. MechoMedics ran Diagnosis and recalibrated the OCS and all warning lights were gone.

7. 2013 Toyota Corolla with 2ZR-FE Engine bought brand new but off Dealership warranty, it had a single cylinder misfire and several suggestions of Fuel Pump, Fuel filter, Spark Plug, Ignition Coil and even Engine Replacement were in view as a fix. We ran Diagnosis and a Mechanical fault in the Valve Timing system for the misfiring cylinder was detected.

8. 2012 Toyota Hilux that has issues with transmission selection and we were vontacont for Diagnosis. We Diagnosed and discove a ECM Mismatch and we supplied the right ECM and the TranmTransmission worked fine.

9. 2008 Ford Mondeo 2.3L DURATEC 4 Cylinder Engine with poor idle and no acceleration was a case on our clients car and we ran DIAGNOSIS and we had Throttle to ECM communication Diagnostic Trouble Codes (DTCs), with suggestions from other Technicians recommending ECM replacement, we knew better with our Pin-point Testing which revealed faulty Throttle Assembly and this was supplied and the Car runs fine.

10. 2009 Corolla S/A spec. 2ZR-FE Engine with Inoperative Speedometer, MIL, Electronic Power Steering (P/S) and ABS Warning Light and Messages. Our Diagnosis revealed a faulty and Open Circuit in FR and FL Wheel Speed Sensor. We fixed this and all faults and warning lights were gone.

There are still more but I realise you now understand the benefit of Automobile Diagnosis, be it that you wanna have MechoMedics Diagnose and supply your Mechanic guide in fixing your vehicle fault, or you want us to Diagnose and supply you the right Spare Parts or you want us to Check out the numerous warning lights and Fix the vehicle and fix its Electrical and Mechanical faults for you or you want to calibrate or reprogramme the ECM or find out if your ECM is faulty, we will always be there to give your Automobile a longer service life.

In summary, DIAGNOSIS helps you address the following issues on your Vehicle:
1. Drop in Engine Performance
2. Drop in Fuel Economy
3. Reoccurring faults
4. Degrade and quick failure of vehicle systems
5. Expensive and recurrent vehicle repairs
6. Developing vehicle faults
7. Display of several warning lights
8. Wrong wiring and use of wrong parts on vehicle
9. Driveability faults and Transmission issues
10. Shortage of Manufacturer Technical information to Mechanic and Automobile Technicians.
