TEST PROCEDURE
1. Turn the engine off.
2. Unlatch, lift, and secure the right side
engine service access door.
3. Locate and remove the two in-line connec-
tors that attach the idler solenoid leads to
the wiring harness leads (#226A, #237A).
See Figure F.5 and the Wiring Diagram.
4. Check the coil resistance. The normal
resistance is approximately 4.5 ohms. If the
coil resistance is not correct, the solenoid
may be faulty. Replace.
5. Using the external 12VDC supply, apply
12VDC to the solenoid leads. The solenoid
should activate. The solenoid should deac-
tivate when the 12VDC is removed.
6. If the solenoid does not operate properly,
check for a mechanical restriction in the
linkage.
7. If the linkage is intact and the solenoid does
not operate correctly when the 12VDC is
applied, the solenoid may be faulty.
Replace.
8. Replace leads #226A and #237A to the cor-
rect in-line connectors. See Figure F.5 and
the wiring diagram. Replace any previously
removed wire wraps.
9. Close and secure the right side engine ser-
vice access door.
