1-15 UNIT CHECK
WARNING

Driving a vehicle with SST (EFI computer check sub-harness, etc.) being connected might
cause an error operation to occur, which is extremely dangerous. Make sure that SST has
been disconnected before driving the vehicle.
1-15-1 FUEL PRESSURE CHECKING
WARNING

Never use fire during the work.
Place cloth, etc. to prevent fuel from splashing.
1. Connect DS-.
2. Disconnect the fuel hose from the fuel delivery pipe inlet and attach the fuel pressure gage to the
pipe via a 3 way.
3. Set the ignition switch to "ON".
4. Carry out the active test [fuel pump] by using the DS-.
5. Measure the fuel pressure when the fuel pump is driven.
SPECIFIED VALUE: 3245 kPa {3.3 0.05 kgf/cm2
No significant variation taking place.
