(E) Data Link - If the engine has a 31 pin MIC connector, refer to the following illustrations: Illustration 1, Illustration 3, Illustration 4 and Illustration 6.If the engine has a 70 pin MIC connector, refer to the following illustrations: Illustration 2, Illustration 3, Illustration 5 and Illustration 6.
Thoroughly inspect the following electrical connectors.
ECM connector J1/P1
Data link connectors J60 (if equipped), J80 (if equipped) and J20/P20
If equipped, 31 pin Machine Interface Connector J20, pin 15 and pin 16.
If equipped, 70 pin Machine Interface Connector J20, pin 4 and pin 5.Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the data link.
Check the ECM connector (Allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the harness and wiring for abrasion and pinch points from the connector to the ECM. Expected Result:All connectors, pins and sockets should be completely coupled and/or inserted. The harness and wiring should be free of corrosion, abrasion and/or pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - There is a fault in a harness or a connector.Repair: Perform the following repair:Repair the connectors and/or the harness, or replace the connectors and/or the harness. Ensure that all of the seals are correctly installed and ensure that the connectors are completely coupled.Use the electronic service tool to clear any logged diagnostic codes and verify that the repair has eliminated the fault.STOPTest Step 2. Determine the Type of Fault on the Data Link
Connect the electronic service tool to the J60 or J80 diagnostic connector.
Start the engine. Expected Result:Result 1 The engine starts. The electronic service tool powers up and the electronic service tool communicates without error.Result 2 The engine starts. The electronic service tool powers up but an error is displayed.Result 3 The engine cranks but the engine will not start regardless of the condition of the electronic service tool.Result 4 The engine will not crank regardless of the condition of the electronic service tool.Result 5 The engine starts but the electronic service tool does not power up.Results:
Result 1 - There is not a problem with the data link at this time. If an intermittent condition exists, thoroughly inspect all wiring and connectors. Repair: Perform the following diagnostic procedure:Troubleshooting, "Electrical Connectors - Inspect"STOP
Result 2 - The electronic service tool displays an error message. The ECM is receiving battery power. Proceed to Test Step 3.
Result 3 - Repair: Perform the following diagnostic procedure:Troubleshooting, "Engine Will Not Crank"STOP
Result 4 - Repair: Perform the following diagnostic procedure:Troubleshooting, "Engine Cranks But Will Not Start"STOP
Result 5 - The electronic service tool does not power up or the communications adapter does not power up. Ensure that the ECM is receiving the correct battery power. Proceed to Test Step 4.Test Step 3. Check the Battery Voltage at the ECM
Ensure that the electronic service tool is connected to the J60 or J80 diagnostic connector.
Disconnect ECM connector P1 from ECM connector J1.
Turn the keyswitch to the ON position.
Measure the voltage on P1 between sockets P1:56 (Battery +) and P1:68 (Battery -).
On engines with a 70 pin MIC, measure the voltage on P1 between sockets P1:57 (Battery +) and P1:69 (Battery -).
Measure the voltage on P1 between sockets P1:70 (keyswitch) and P1:68 (Battery -). Refer to Illustration 3.Expected Result:The voltage is between 22.0 Volts DC and 27 Volts DC for a 24 Volt system and between 11.0 Volts DC and 13.5 Volts DC for a 12 Volt system when the key
