BEARING 7R3565 - Caterpillar

Note: Prior to beginning this procedure, inspect the harness connectors that are involved in this circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure, and in good condition. If a problem with a connection is found, correct the problem and verify that the diagnostic code is active before performing a troubleshooting procedure.Possible causes for an FMI 3 Diagnostic Code are:
The energize circuit is shorted to another voltage source.
The switch panel has failed.
The ECM has failed. A failure of the ECM is unlikely.Possible causes for an FMI 6 Diagnostic Code are:
The energize circuit of the module is shorted to a ground source.
The control module has failed.
The switch panel has failed.
The ECM has failed. A failure of the Machine ECM is unlikely.

Schematic for the "Window Wiper Control Module"
Note: The diagram above is a simplified schematic of the Switch Panel connections. The schematic is electrically correct. However, not all of the possible harness connectors are shown. Refer to the latest revision of Electrical Schematic , UENR5374 for machines with sales model numbers 312F or 313F. For machines with sales model number 316F or 318F refer to Electrical Schematic , UENR5345. Diagnostic Trouble Code Procedure

Troubleshooting Test Steps Values Results
1. Identify The Active FMI Code Associated With The Solenoid Circuit
Code present FMI 3 diagnostic code, proceed to Test Step 2.
FMI 6 diagnostic code, proceed to Test Step 5.

2. Check The Energize Circuit Of The Wiper Control For A Short
A. Turn the key start switch and disconnect switch to the OFF position.
B. Disconnect all harness connectors from the "Switch Panel".
C. Disconnect the wiper control module from the machine harness.
D. At the "Switch Panel" identify the wiper intermittent pin locations (refer to the schematic above).
E. Measure the resistance from the wiper intermittent connectors on the "Switch Panel" and all other contacts of the "Switch Panel".
Each reading is greater than 5K Ω. OK - All measurements are greater than 5K Ω.
Proceed to Test Step 3.
NOT OK - Resistance is less than 5 Ω, a short exists in the signal circuit.
Repair: Repair or replace the machine harness.
Note: A resistance greater than 5 Ω but less than 5K Ω indicates a loose or corroded connection in the circuit. A resistance measurement greater than 5K Ω indicates an open in the circuit.
STOP
3. Check The Operation Of The ECM
Note: The disconnect and the key start switch remain in the OFF position. The machine harness connectors for the wiper module and the "Switch Panel" remain disconnected.
A. At the machine harness connector F-C13 for the "Switch Panel", use a 151-6320 Removal Tool to remove the signal wire and socket.
B. Reconnect the machine harness F-C1, F-C13, and F-C2 connectors to the "Switch Panel".
C. Turn the disconnect switch and the key start switch to the ON position.
D. Observe the status of the active diagnostic code.
The diagnostic code is no longer active. OK - The diagnostic code is no longer
