Find the fault.
Find the fault.

Fix the right thing.
Warning light on, running badly or refusing to start? Strive Motors carries out proper vehicle fault diagnosis — using the code as a clue, then testing what is actually happening before recommending parts.
✓ Workshop + suitable mobile appointments
✓ Fault codes, live data and real testing
✓ Clear findings and the next repair step
DIAGNOSIS BEFORE PARTS
A fault code is the start of the diagnosis — not the answer.
A code tells us what a control unit has noticed. It does not automatically prove that the component named in the code has failed.
EXAMPLE SIGNALSensor-related fault codeWhat could actually cause it?
Sensor itselfWiring / connectorPower or groundAnother component affecting the readingMechanical faultAdaptation / system behaviour
The job is to test which explanation fits the vehicle — not just replace the first part mentioned by a scan tool.
WHAT WE INVESTIGATE
Symptoms are where the diagnosis starts.
You do not need to know the technical fault before booking. Tell us what the vehicle is doing, when it happens and what warnings you can see.
Running faults
Misfires, rough running, hesitation, poor starting, loss of power and intermittent behaviour.
Limp mode & emissions
Reduced power, DPF faults, emissions issues, AdBlue/SCR warnings and related drivability problems.
Starting & charging
Non-starts, battery concerns, alternator/charging faults and starter-system problems.
Electrical faults
Electrical symptoms, sensor faults, power/ground problems, wiring concerns and intermittent failures.
Mechanical symptoms
Overheating, unusual system readings and faults where scan data needs checking against the physical vehicle.
THE DIAGNOSTIC PROCESS
From symptom to a sensible next step.
Not every fault needs every test. The process follows the evidence and becomes more targeted as we understand the vehicle.
Tell us what it is doing
Symptoms, history and when the fault occurs give the first useful direction.
Scan the vehicle
Read relevant fault codes, module information and stored fault conditions.
Analyse the data
Use live data, freeze-frame information and system behaviour where relevant.
Test the suspected fault
Carry out appropriate electrical, sensor, mechanical or visual checks.
Confirm the likely cause
Bring the test results together before recommending the repair direction.
Explain what happens next
We explain the findings and can quote for repair where the next step is clear.
PROPER FAULT FINDINGData only becomes useful when it is compared with what the vehicle is actually doing.
MORE THAN A CODE READER
Testing the system, not guessing at the part.
Depending on the fault and vehicle, diagnosis can draw on several types of evidence. We only highlight capabilities that form part of normal automotive fault-finding work.
01Fault-code and control-module information
02Live vehicle data and system behaviour
03Electrical and sensor testing where appropriate
04Wiring, connector and power/ground checks
05Mechanical and visual inspection
06Pressure / temperature readings where the fault requires them
WHAT YOU ARE PAYING FOR
A useful answer — not just a list of codes.
The aim is to leave you with a clearer understanding of the vehicle and a sensible repair direction.
Fault investigation
Time spent following the symptoms and evidence rather than treating the scan result as a parts list.
Explanation of findings
What we found, what the evidence points towards and what still needs proving if the fault is unusually complex.
Recommended next step
A clear repair direction and, where possible, a quotation for Strive Motors to carry out the work.
WORKSHOP + MOBILE
Bring the vehicle to us — or start the investigation where it is.
The right setting depends on the fault. Some symptoms are ideal for an initial mobile investigation; others need workshop equipment or more involved access.
Best when the fault needs more equipment, access or time.
- Vehicle lifts and workshop access
- Longer or more involved testing
- Mechanical strip-down where authorised
- Direct transition from diagnosis into repair
Useful when the vehicle is at home, work or cannot easily come to us.
- Non-start and initial fault investigation
- Warning lights and running faults
- Suitable electrical / charging checks
- Clear direction if workshop follow-up is required
VEHICLE CANNOT COME TO US?
Use the right Strive service for the situation.
Diagnostics, roadside assistance and recovery now connect naturally, so a fault can move from first investigation to workshop repair without the customer having to start again.
Breakdown Assistance
A mobile technician attends the vehicle to diagnose the problem and repair it roadside where practical.

If workshop-level diagnosis is required, Strive can also physically transport a suitable vehicle to the agreed destination.

WHY STRIVE FOR DIAGNOSTICS?
Fault finding that connects directly to the repair.

DIAGNOSTICS FAQ
Useful answers before you book.
What is a vehicle diagnostic test?+
It is a fault investigation. We start with the symptoms and use the appropriate scan information, live data, electrical/mechanical tests and physical checks to work towards the cause.
Is a fault-code scan the same as diagnostics?+
No. A scan is one part of diagnostics. A code is evidence that a control unit has seen something abnormal; it does not automatically prove that the named component is faulty.
How long does diagnostics take?+
The standard diagnostic appointment covers the initial diagnostic hour. Some faults can be identified within that period; intermittent or complex faults can require further authorised investigation.
Can you diagnose a vehicle that won't start?+
Yes. Non-start faults are a common reason for diagnosis. Depending on the fault and location, this may begin as a mobile appointment or require workshop follow-up.
Do you diagnose electrical faults?+
Yes, where the fault is within our normal automotive diagnostic capability. Electrical diagnosis may include power/ground, wiring, connector, charging and sensor checks as appropriate.
Can you diagnose my car at home or work?+
Suitable faults can be investigated through a mobile diagnostic appointment. If the diagnosis needs workshop equipment or more invasive access, we will explain the next step.
Will you repair the vehicle after diagnosing it?+
Where the cause is established and the repair is within our service capability, Strive Motors can quote for and carry out the repair.
What if the fault takes longer than the initial appointment?+
We explain what has been established and what further testing is recommended before carrying out additional diagnostic time. Complex faults are not silently turned into unlimited labour.
Do you work on all makes and models?+
We work across a broad range of makes and models. Diagnostic depth can vary by vehicle/system, so tell us the registration and symptoms when booking.
Can you just clear the warning light?+
Warning lights should be investigated rather than treated as a code-clearing service. Where appropriate, faults can be cleared after diagnosis or repair and the system checked to see whether the fault returns.
