DIAGNOSE THE CAUSE
More than reading fault codes.
A diagnostic trouble code is a starting point, not a complete diagnosis. The same code can be triggered by wiring, power supply, sensors, actuators, communication faults or a mechanical problem. Replacing the component named in a code without testing can waste time and money.
At SHED 31 we use scan data together with electrical testing and real-world fault finding. Where required, this can include live data, power and ground checks, continuity and voltage-drop testing, sensor and actuator testing and CAN/LIN network investigation.
Warning lights & fault codes
Engine, ABS, airbag, transmission and other control-system faults investigated using scan data and targeted testing.
No-start diagnostics
Testing power supply, communication, sensors, starting systems and other causes of crank/no-start or no-crank conditions.
CAN/LIN network faults
Investigation of lost communication, modules that disappear from the network and wiring or supply problems affecting vehicle networks.
Battery drain & charging faults
Parasitic drain, charging issues, power distribution and electrical problems that can repeatedly flatten a battery.
Auto electrical fault finding in Cork.
Modern vehicles rely on interconnected electronic systems. A single damaged wire, poor ground, water ingress or power-supply problem can create multiple warning lights and seemingly unrelated fault codes. We trace electrical faults methodically instead of replacing parts until the symptom disappears.
Diagnostic equipment is only part of the job.
Professional scanners can identify stored faults, live values and communication status, but they do not automatically tell you which component is bad. Effective diagnostics means interpreting the data, checking the circuit and confirming the cause. That approach is particularly important on modern vehicles where one electrical fault can affect several control modules.
Diagnostics for modern petrol, diesel, hybrid and EV vehicles.
SHED 31 works across modern petrol and diesel vehicles as well as suitable hybrid and electric vehicle systems. Hybrid and EV work is accepted by appointment, including diagnostic investigation and high-voltage battery diagnosis where appropriate.
Car diagnostics in Cork and surrounding areas.
Our workshop is based in Aherla, Co. Cork, convenient for Ballincollig, Macroom, Bandon, Coachford and the wider Cork area. If you have a warning light, electrical problem or difficult fault, send the registration, make/model, year and symptoms on WhatsApp before travelling.
