Built around the actual diagnostic workflow. Input what you have, get ranked causes, follow the path.
Input DTCs and symptoms. Get ranked differentials with platform-specific failure patterns for AU-spec vehicles.
Every diagnostic stays with the vehicle's plate Soft-ID. When that HiLux comes back in 6 months, your notes are right there.
Not generic fault codes. Ranked differentials with reasoning, built around the specific vehicle and scan data you have in front of you.
Ranked Probable Causes
Rail pressure 22,000 kPa vs spec 28,000+ kPa at idle, LTFT +22%. HP4 pump is a known wear item on high-mileage 1GD-FTV units.
High LTFT and low rail pressure can result from injector return exceeding spec. Perform injector return test at idle.
Low supply-side pressure would starve the HP4. Check pre-supply pressure at HP4 inlet (spec: 400–500 kPa).
Known Issue / TSB
1GD-FTV high-pressure fuel pump wear at high mileage — revised HP4 pump kit available from Toyota
Applies to: Toyota HiLux / Prado 2015–2020 with 1GD-FTV
