INSPECTION
1. INSPECT AIR SWITCHING VALVE ASSEMBLY
(a) Measure the resistance according to the value(s) in the table
below.
Standard Resistance:
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
1 - 5
20°C (68°F)*
4.5 to 5.5 Ω
1 - Body ground
Always
1 MΩ or higher
5 - Body ground
HINT:
*: Make sure that the air switching valve is at ambient
temperature before measuring the resistance.
NOTICE:
When applying voltage, do not touch terminals 2, 3 and 4.
If the result is not as specified, replace the air switching valve
assembly.
NOTICE:
Make sure the applied pressure is 30 kPa (0.3 kgf/cm
2
, 4.4 psi) or less
If the result is not as specified, replace the air switching valve assembly.
