3.Apply battery voltage to the air pump connector.
| 1.Install the air hose to
the differential. |
|
2.Connect a pressure gauge
to the air pump discharge outlet nozzle, via the air hose
and
T-joint. 3.Apply battery voltage to the air pump connector. |
 |
4.Measure the time when the
pump starts and stops operating, and if it stops within 5
seconds,
the pressure switch inside the pump is
normal. 5.Measure the pressure 10 - 20 seconds after the pump has stopped. Standard value: 24.5 - 39 kPa (-30 - 0°C), 24.5 - 34 kPa (0 - 100°C) 6.If the pressure is within the standard value, the release valve inside the pump is normal. 7.Check the pump does not begin operating for 5 minutes after it has stopped. 8.If the inspection for steps 4-7 is normal, the pump is fully operational. |
