Checking the Pressure of the Air bags

You can find the pressure leakage of the Air bags by this checking.
Remove the Under cover and the Side cover.
Connect the Air pressure gauge (WEP000S8908) and the
Hose (WEP000K8917) to the Hose from the Under box,
which you want to check the air pressure.
1. Push the Off/On button on the Controller and push the buttons of the operations (shoulder, hand/arm, lower back, and leg/
foot) that you check.
2. Push the AIR INTENSITY button on the Controller, and check the air pressure. If the values are within the tolerance, there is
nothing wrong with Air bags, Pump, and Air hoses. If not, the following reasons are assumed:
• Hoses between Air bags and Pump are bent and loose.
• Operation failure of each Electromagnetic valves
• Operation failure of Pump and decrease of the output voltage of the Sub PCB
• Rupture of each Air bags
