VACUUM HOSE ROUTING


NOTE: The vacuum source hose at the intake manifold may be kinked or collapsed. Check this before continuing with the test!

1. Place the transaxle in FIFTH (5th) gear.
2. Using an ohm meter, check for continuity between the select switch terminals (Connector M12 - 2wht) located on top of the transaxle.

Continuity
Should exist
Replace the switch if it fails the above test.

3. Place the transaxle in REVERSE gear.
4. Using an ohm meter, check for continuity between the reverse switch wires RED - RED/BLU (Connector M13 - 4wht) located on top of the transaxle.

Continuity
Should exist
Replace the switch if it fails the above test.

5. Turn the key to the ON position.
6. Using a volt meter, check for battery voltage between the BLK/WHT wire at the select switch harness connector and ground.

Voltage
Should exist
Check for an open circuit between the ignition switch and the component if the above test fails.

7. Using a volt meter, check for battery voltage between the RED/BLU wire at the reverse switch harness connector and ground.

Voltage
Should exist
Check for an open circuit between the ignition switch and the component if the above test fails.

8. Turn the key to the OFF position and disconnect the vacuum hoses on the select control valve (solenoid).
9. Connect a hand vacuum pump to the fitting that the "B" hose was removed from and apply vacuum.

Vacuum
Should be present at the fitting that the "C" hose was disconnected.
Replace the select control valve if it fails the above test.

10. Apply power to the solenoid and apply vacuum to the fitting once more.

Vacuum
Should be present at the fitting that the "A" hose was disconnected.
Replace the select control valve if it fails the above test.

11. Disconnect the hoses from the selector actuator.
12. Using a vacuum pump, apply vacuum to the fittings on the actuator.

Vacuum
Should hold at both fittings.
Replace the select actuator if it fails the above test.

13. Start the engine and connect a hand vacuum pump to the fitting that the "B" hose was disconnected.

Vacuum
Should exist
Check the vacuum hoses for splits, kinks or mis-routing if the above test fails.

NOTE: If all of the above tests reveal no faults, the relay (located behind the L.H. side of the dash) will need to be replaced. The relay is solid state and it can not be tested.
