An app that uses real-time sensor data and machine learning to diagnose cooling system overpressure and unexplained coolant loss. It provides step-by-step diagnostic procedures for intermittent pressure problems that scanners miss.
“Vehicle owner experiences unexplained coolant loss when towing heavy loads over mountain passes, requiring frequent topping up and raising concerns about underlying cooling system issues.”
“Unable to refill coolant system completely after engine rebuild; only 2 of 6.5 liters goes in, preventing circulation.”
Addressing physical incompatibility of OBD2 connectors across vehicles, especially heavy-duty trucks, by providing a visual adapter guide and diagnostic workflow to prevent issues like engine shutdown when plugging sensors.
“Cannot diagnose P0420 code on Volvo XC90 without replacing expensive catalytic converter to confirm root cause.”
“OBD2 connector physically incompatible with vehicle's DLC port despite both having 16 pins.”
An app that aggregates model-specific TSBs, common failure patterns, and guided diagnostic workflows for Hyundai Elantra and similar vehicles, helping owners and technicians quickly pinpoint interrelated issues like parasitic drain and vacuum leaks.
“Technician needs to identify the cause of a parasitic battery drain on a 2017 Hyundai Elantra, requiring access to known TSBs, common module failures, and fuse test priorities.”
“Car owner cannot get mechanics to diagnose interrelated hissing, surging, and stalling issues in a 2014 Hyundai Elantra.”
A mobile app that guides users through brake bleeding and diagnoses hydraulic issues by leveraging vehicle-specific procedures and sensor data. It solves the persistent soft pedal problem caused by air trapped in ABS or rusted bleeder screws.
“Car owner cannot visually inspect brake pad life and rotor condition on the inside of the wheel without removing the tire and caliper.”
“Brake pressure fades in a vehicle with code RSC, requiring diagnosis and repair.”
An app that interprets OBD scanner data in real-time and guides users through a structured diagnostic workflow. It reduces guesswork and unnecessary part replacements by providing plain-language explanations and step-by-step troubleshooting.
“Vehicle battery keeps dying due to unidentified parasitic electrical draw.”
“Car loses power under heavy load at low RPM with concurrent voltage drops, causing conflicting diagnoses between transmission and electrical issues.”
An affordable smartphone-based app that guides home mechanics through accurate wheel alignment using the phone's sensors. It provides step-by-step instructions, records measurements, and verifies results without expensive equipment.
“Vehicle owner is unsure if wheel alignment is correct after a second attempt, concerned caster is not adjustable.”
“New car owner cannot determine if paint defect is a clear coat failure or external damage, and faces costly repairs without clear responsibility.”
A mechanic needs to confirm whether intermittent misfire and dash light issues on a 2018 Honda CRV 1.5T are caused by a head gasket leak between cylinders 2 and 3, lacking experience with this engine pattern.
Mechanics lack a structured diagnostic process leading to guesswork and unnecessary part replacements
Intermittent ESC light, early indicator cancellation, and trip computer glitches after steering angle sensor recalibration, leading to uncertainty about which steering column part to replace.
Unable to permanently diagnose and fix intermittent P0087 and P0088 fault codes causing limp mode on a Skoda Octavia 1.6 TDI after replacing injectors, rail pressure sensor, rail, and metering valve multiple times.
A car owner is unable to identify the source of a vibration/noise after an engine replacement, despite multiple checks, and the dealer provided no effective solution.
A car owner with a persistent tick/misfire at cruising speed cannot diagnose the root cause despite extensive testing, risking the vehicle's long-term reliability.
A 1994 F-150 with E4OD transmission has erratic shifting after replacing the MLPS sensor, with codes indicating shift solenoid and trans temp issues, and the owner needs diagnostic guidance to avoid replacing parts unnecessarily.
Intermittent electrical issues in vehicles are difficult to diagnose because they don't always present when testing, requiring extensive manual checks.
Vehicle mechanic struggles to diagnose a no-start condition after replacing fuel tank and pump on a 1988 Ford E150, with fuel not reaching the high-pressure pump.
Vehicle no-start after fuel tank and pump replacement on a 1988 Ford E150, with unresolved diagnostics despite filter replacement.
Difficulty diagnosing and sourcing parts for a misfiring engine with low RPM, due to obsolete distributor components.
Intermittent brake caliper seizure is hard to diagnose because it only happens under certain conditions and is not detectable by visual inspection.
After a transmission replacement, the user cannot fill the full 9.9L capacity through the fill bung; only 3L fits, and they fear damaging the transmission by running it dry to circulate fluid.
Diagnosing a persistent ABS wheel speed sensor code (C0050-06) on a 2012 Chevy Cruze, after replacing sensor and wheel bearing, needing to trace wiring upstream without schematics.
Need to diagnose whether a 2019 Nissan Kicks alternator is faulty, but unsure how to test a clutched alternator on a modern vehicle.
Paint color matching is frequently inaccurate, requiring manual tinting on almost every job because the color camera is unreliable.
A DIY car mechanic needs a bidirectional diagnostic tool under $400, but is confused by similar-looking options, hidden subscription costs, and uncertain which tool offers better capability for mixed fleet repairs.
A Subaru WRX owner with a tuned car cannot diagnose a persistent CEL (random misfire, excessive E85) and fuel tank whistle because his Accessport (AP) was stolen, and the replacement cost is prohibitive ($800+), his tune is locked to the stolen AP, and the tuner refuses to work without an AP.
User cannot identify a transmission part and needs a thread repair tool recommendation.
Unable to synchronize windshield wiper motor after replacement, causing wipers to rotate into the cowl instead of up the windshield.
