4            Expected Result:The actual injection actuation pressure for each step and the desired injection actuation pressure for each step are within 1379 kPa (200 psi).Note: Under some situations, the injection actuation pressure may not change. Use this step to compare the pressure from the pressure gauge to the pressure that is displayed by Cat ET.Results:
OK - The actual injection actuation pressure and the desired injection actuation pressure are within 1379 kPa (200 psi).Repair: Contact your Engine Technical Communicator (TC) for assistance.STOP
Not OK - The actual injection actuation pressure and the desired injection actuation pressure are not within 1379 kPa (200 psi). Proceed to Test Step 12.Test Step 12. Check the Oil Pressure at the Pump (Deadhead Test)
Escaping fluid under pressure, even a pinhole size leak, can penetrate body tissue, causing serious injury, and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.Always use a board or cardboard when checking for a leak.
Disconnect the high pressure oil line from the unit injector hydraulic pump. Install a 8T-0852 Pressure Gauge onto the outlet port of the pump.Note: Ensure that the pump is supplying oil only to the gauge.Note: The pressure readings may vary between gauges.
Install a 224-9282 Adapter Cable As at the J500/P500 connectors. Connect one end of the adapter cable to the IAPCV and connect the other end to the harness connector.Note: There must be a continuous electrical connection between the ECM and the unit injector hydraulic pump. The improper connection or the incomplete connection of the adapter cable may provide incorrect results.
Connect a multimeter that is capable of measuring current that is 0 to 1,000 milliampere in series with the adapter cable. Select the lowest current range for the multimeter that is greater than one amp.Note: If the multimeter is not set to the correct scale, the following measurement may provide misleading results.
Crank the engine and record the following data:________ Observed pressure reading from the pressure gauge________ Observed engine speed from Cat ET________ Observed "Injection Actuation Output Percent" from Cat ET________ Current reading from the ammeterExpected Result:The oil pressure is above 26.5 MPa (3843 psi) and the current is above 400 mA.Results:
OK
