Test harness for low oil pressure (A) Socket A of 8T-8730 Connector Socket. (B) Socket B of 8T-8730 Connector Socket . (C) Socket C of 8T-8730 Connector Socket . (R) 1000 Ohm ten turn potentiometer.Note: Socket C of 8T-8730 Connector Socket (C) connects to the wiper of the potentiometer (R) .This procedure enables the service personnel to verify that the protection for low engine oil pressure is functioning. This procedure controls the oil pressure signal to the module for pressure and temperature without affecting the engine lubrication system. Engine shutdown and the alarm are verified at idle speed and rated speed.Note: If equipped, the fault indicator for low oil pressure and the horn on an alarm module will activate at 34 kPa (5 psi) above the value for engine shutdown.The trip conditions for a shutdown that is caused by low oil pressure at idle speed are listed below.
The engine speed is less than the value for oil step speed.
The engine oil pressure is less than the value which will cause a shutdown for oil pressure at idle speed.The trip conditions for a shutdown that is caused by low oil pressure at rated speed are listed below:
The engine speed is greater than the value for oil step speed.
The engine oil pressure is less than the value which will cause a shutdown for oil pressure at rated speed.
Determine the programmed Status Control Module (SCM) setpoint for: oil step speed, shutdown for oil pressure at idle speed and shutdown for oil pressure at rated speed
Turn the Engine Control Switch (ECS) to the OFF/RESET position.
Disconnect the connector for the engine oil pressure sensor from the engine harness. Connect the test harness
