IDLER SOLENOID TEST PROCEDURE (CONTINUED)
TEST PROCEDURE
1. Turn the engine off.
2. Unlatch, lift, and secure the right side engine ser-
vice access door.
3. Locate and separate J55/P55 connector that
attaches the idler solenoid leads to the wiring har-
ness leads (#226, #227 and #232L). See Figure
F.4 and the Wiring Diagram. Remove and replace
necessary wire wraps.
4. Check the pull-in coil resistance (White to Black
#227 to #232L). The normal resistance is approx-
imately 0.2 ohms.
Check the hold-in coil resistance (Red to Black
#226A to #232S). Normal coil resistance is
approximately 11 ohms.
If either coil resistance is not correct, the solenoid
may be faulty. Replace.
5. Using the external 12VDC supply, apply 12VDC to
the pull coil terminals (#227 to #232L +). The sole-
noid should activate.
When the solenoid activates, remove the voltage sup-
ply immediately. Leaving the external supply con-
nected to terminals #232M and #265 for longer than
three seconds will damage the coil.
• The solenoid should deactivate when the 12VDC is
removed.
6. If the solenoid does not operate properly, check for a
mechanical restriction in the linkage.
7.
Using the external 12VDC supply, apply 12VDC to the
hold idler solenoid terminals for the hold-in coil (#226
to #232 +). Push in the solenoid plunger. With 12
VDC applied to the hold-in coil, the plunger should
stay in until the 12 VDC is removed.
8. If the linkage is intact and the solenoid does not oper-
ate correctly when the 12VDC is applied, the solenoid
may be faulty. Replace.
9. Replace harness connectors. See Figure F.4 and
the Wiring Diagram. Replace any previously
removed wire wraps.
10. Close and secure the right side engine service access
door.
