Diagnostic Engineer · iCarsoft · Electrical & electronics
Brian is a diagnostic engineer on the iCarsoft team who lives on the electrical side of the car — control circuits and wiring, relays and solenoid drivers, charging and starting systems, and body electronics.
What I cover
- Control circuits, wiring and connectors.
- Relays and solenoid control circuits.
- Charging and starting systems.
- Body and comfort electronics.
How I write these guides
Electrical faults live in the wiring as often as the part, so every guide I write walks the circuit — voltage, ground, and the connector in between — instead of jumping to the component. Checked against the SAE J2012 definition and public OBD references, and updated as new failure patterns turn up.
A bad solenoid is so often a bad connector — these guides use the live circuit data an iCarsoft tool reads so you fix the actual break, not the symptom. Browse the full library on the OBD-II Codes blog.
