Air Switching Valve -- Inspection

1. INSPECT AIR SWITCHING VALVE ASSEMBLY

Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection
Condition
Specified Condition
1 - 2
20°C (68°F)
4.5 to 5.5 Ω
1 - Body ground
Always
1 MΩ or higher
2 - Body ground
HINT:
When measuring the resistance, make sure that the surface temperature of the air switching valve is 20°C (68°F).
If the result is not as specified, replace the air switching valve assembly.
