BEARING-SLEEVE 8S6511 - Caterpillar

Test Step 1. INSPECT THE ELECTRICAL CONNECTORS AND WIRING.
Turn the keyswitch to the OFF position.
Check the connectors and wiring for the following conditions: damage, corrosion, abrasion, pinch points and incorrect attachment. Expected Result:None of these conditions are present.Results:
OK - None of these conditions are present. Go to Test Step 2.
NOT OK - Repair the connector or replace the connector.STOPTest Step 2. VERIFY THAT TERMINATION RESISTORS ARE INSTALLED ON THE ENDS OF THE DATA LINK.
The keyswitch remains in the OFF position.
Disconnect the J1 connector from the ECM.
Disconnect the power train control processor (PCP) from the data link. Remove the PCP by disconnecting the drop to the PCP from the TEE connector.
Disconnect the ETP from the data link. Remove the ETP by disconnecting the drop to the ETP from the TEE connector.
Disconnect the marine power displays from the J1939 data link.
Measure the resistance between the J1939 + pin and the J1939 − pin on the J1 connector for the ECM. Refer to table 1 for the pin numbers.

J1-15 J1939 shield Expected Result:The resistance is between 57 and 63 Ohms.Results:
OK - The resistance is between 57 and 63 Ohms. Go to Test Step 5.
NOT OK - The resistance is between 38 Ohms and 42 Ohms. There appear to be 3 terminating resistors in the data link or there is a short circuit.Repair: Verify that there are only 2 terminating resistors in the circuit. Recheck in order to ensure the resistance is between 57 and 63 Ohms.STOP
NOT OK - The resistance is between 43 Ohms and 56 Ohms. Verify the resistance reading. If the reading is the same, go to Test Step 7
NOT OK - The resistance is between 57 Ohms and 63 Ohms. The data link appears to be properly connected. Go to Test Step 5.
NOT OK - The resistance is between 64 Ohms and 113 Ohms. Verify the resistance reading. If the reading is the same, go to Test Step 7.
NOT OK - The resistance is 114 Ohms to 126 Ohms. There is only one resistor in the data link or the data link has an open circuit in the data wire. If the connectors are properly connected and there are two terminating resistors, go to Test Step 3.
NOT OK - The resistance is greater than or equal to 127 Ohms. Go to Test Step 3.
NOT OK - The resistance is less than or equal to 37 Ohms. There is a short circuit in the data link. Go to Test Step 7.Test Step 3. MEASURE THE RESISTANCE IN THE J3 HARNESS BETWEEN THE MARINE JUNCTION BOX AND THE ECM.
The ECM and the ETP remain disconnected.
Disconnect the terminating resistor from the engine harness.
Disconnect the J3 cable for the customer connector from the MJB.
Install a jumper between the J1939 data + contact on the ECM and the J1939 data − contact on
