Modern engine systems are more efficient than ever, but that efficiency brings added complexity when diagnosing faults. Boost pressure issues, airflow faults, and sensor-related DTCs can often lead technicians towards incorrect conclusions if components are not properly validated.
With Guided Component Tests (CTM), there is no need for guesswork. You gain access to structured, step-by-step testing procedures and workflows that allow you to verify components quickly and identify the root cause of issues quickly and with confidence.
Traditional diagnostics often leads to:
Replacing components based on fault codes alone
Following lengthy test procedures without direction
Missing mechanical causes behind electrical faults
However, real-world faults are often influenced by:
Airflow restrictions or boost leaks
Known system behaviours and failure patterns
Mechanical faults that affect sensor readings
Guided Component Tests combine accurate data, system knowledge, and structured workflows, helping you move directly to the correct diagnostic path.

Modern diagnostics requires more than reading fault codes, it requires understanding how systems behave in real conditions.
The latest software release expands Guided Component Test (CTM) coverage across key systems, including forced induction and ABS, combining:
These enhancements help technicians move from assumption-based repairs to evidence-based diagnosis, improving efficiency and workshop productivity.
On the Audi A5 2.0L Diesel (2011–2017), ABS warning light faults relating to DTC: C101A-29 (Left Front Wheel Speed Sensor – Range/Performance) can often lead to unnecessary sensor replacement.
Wheel speed signal faults are not always caused by the sensor itself. Intermittent or unstable readings can be influenced by wiring integrity, signal variation under load, or installation conditions, making accurate confirmation essential before component removal.
New in This Software Release: New ABS Troubleshooter Tips highlight known faults and service considerations for this application, supported by enhanced imagery to clearly identify component location and condition. Guided Component Tests can then be used to confirm signal behaviour and circuit integrity, ensuring the fault is correctly identified before any parts are replaced.
A key service consideration on this vehicle is the sensor mounting design. The wheel speed sensor is secured into the hub using a 5mm Allen bolt, and due to corrosion between dissimilar materials, it can become seized in position.
Attempting removal without prior confirmation can result in:
By combining Guided Component Tests with Troubleshooter insight, technicians can confirm the root cause before removal, avoid unnecessary parts replacement, and reduce the risk of additional repair work.
On the Mitsubishi L200 2.4L Diesel (2016–2019), boost pressure faults relating to DTC: P0106 (MAP Sensor/Barometric Pressure Sensor Circuit Range/Performance) can often lead to unnecessary MAP sensor replacement.
Low boost or implausible pressure readings are not always caused by the sensor itself. In many cases, these faults are influenced by airflow and pressure delivery issues within the intake system, where restrictions or blockages can directly affect sensor output.
New in This Software Release: New Engine Troubleshooter Tips highlight known issues within the intake system, supported by enhanced imagery to clearly identify inspection points such as pipework and pressure stubs. Guided Component Tests can then be used to verify sensor output, reference voltage, and ground integrity, ensuring the sensor and circuit are operating correctly before any parts are replaced.
A known consideration on this application is restriction within the intake manifold vacuum pipe or pressure stub, often caused by carbon build-up. This can lead to incorrect pressure readings, triggering limp mode and setting boost-related fault codes.
If these areas are not inspected early in the diagnostic process, the fault may be incorrectly attributed to the sensor itself.
By combining Guided Component Tests with Troubleshooter insight, technicians can identify non-electrical causes of the fault, confirm the true root cause, and avoid unnecessary component replacement.
To fully understand the value of Guided Component Testing, it’s important to see how structured diagnostics apply to real‑world forced induction faults.
Forced Induction Overview and Diagnosis explores:
How turbochargers and superchargers operate within modern engine systems
Why boost- and airflow-related faults often lead to incorrect component replacement
The impact of mechanical issues—such as restrictions, leaks, or carbon build‑up—on sensor readings
How fault codes indicate symptoms, not always the root cause
The article also highlights how Guided Component Tests and Troubleshooter insights support accurate diagnosis by combining known-good data, structured workflows, and real‑world repair intelligence—helping technicians move beyond assumptions and confidently identify the true cause of the fault before replacing components.
