INSPECT AIR SWITCHING VALVE ASSEMBLY
Check for an open in the air switching valve assembly circuit.
Using an ohmmeter, measure the resistance between the terminals.
| Standard resistance |
|---|
| 4.5 to 5.5 Ω at 20 °C (68 °F) |
If the resistance is not as specified, replace the air switching valve assembly.
Inspect the air switching valve assembly operation.
Check that air does not flow from the ports.
Apply battery positive voltage across the terminals.
Check that air flows from the ports.
If operation is not as specified, replace the air switching valve assembly.
