Tools
The checks for a job. The first four are the usual ones. The rest are there when you need them.
- 1VehiclesOne card each. Tick the checks, and that is the list for that vehicle.
- 2Fuel trimsIn the bay. Idle, then 2,500 rpm. Put the result on the visit you have selected.
- 3Battery and chargingKey-on, crank, then idle. Use it when the car is a no-start or the battery is in doubt.
- 4Volumetric efficiencyThe road pull. Once when it comes in, again after the repair.
When you need them
BHP
Same sort of pull, if you want a power figure. An estimate, not a hub dyno.
VE and BHP together
One pull, both graphs, when the job needs both.
Relative compression
A long crank. A low slot is worth a gauge.
DPF pressure
Warm diesel. Idle, then 2,500 rpm. Pressure, temperature and a restriction index. Not the dealer soot percentage.
Freeze frame
What the ECU stored when the fault set.
Mode 06
Catalyst, O2 and EVAP, pass or fail against that ECU.
Min / max
Uses the live list (Road test). Start it, wiggle the connector, then stop.
