Creeper Clutch Solenoid Circuit Failed Open Or Shorted To Ground
Possible failure mode:
1. The creeper clutch solenoid coil failed open.
2. Creeper clutch solenoid wiring failed open or shorted to ground.
Solution:
The transmission controller measures the current draw from the creeper clutch solenoid circuit. If the current draw
is lower than a limit, it means the circuit is open or shorted to ground. If the problem is temperature sensitive, the
solenoid coil may be starting to fail.
1. Remove the controller cover from the rear of the tractor. Visually inspect the wiring harness from the
transmission controller towards the solenoids under the cab. Check the wiring harness for damage.
2. Disconnect connector C350 and C353 from the transmission controller. Measure the resistance between cavity
11 of connector C350 and cavity 3 of connector C353 on the wiring harness side. The resistance should be
around 10 ohms.
If the resistance is dramatically higher than specified, there is an open in the circuit. Check the harness first for
the open. If the harness is okay, check the creeper clutch solenoid for the open.
If the resistance is around 10 ohms, go to next step.
3. Measure the resistance between cavity 11 of connector C350 and the chassis ground. If the resistance is less
than a few ohms, there is a short from the wire to ground. Check the wire for damage between the creeper
clutch solenoid and the transmission controller.
Measure the resistance between cavity 3 of connector C353 and the chassis ground. If the resistance is less
than a few ohms, there is a short from the wire to ground. Check the wire for damage between the creeper
clutch solenoid and the transmission controller.
If the harness is okay check the creeper clutch solenoid.
4. Lift the cab. Disconnect the creeper clutch solenoid connector (C039).
Measure the resistance between pin 1 and pin 2 of the solenoid.
The resistance should be around 10 ohms.
If the resistance is dramatically higher than specified, the creeper clutch solenoid coil is failed open. Replace
the creeper clutch solenoid.
If the resistance is as specified above, check to see if the coil is internally shorted to solenoid case.
5. If no problem is found in above test, check both male and female pins in the cavity 11 of connector C350 and
cavity 3 of connector C353.
Check for loose, bent, or any damaged pins.
