(23) Data link +
(24) Data link - Test Step 1. Inspect Electrical Connectors and Wiring
Thoroughly inspect the following electrical connectors:
P1/J1 ECM connector
Pin D for the data link connector
Pin E for the data link connector
Connectors for the electronic service toolRefer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connectors that are associated with the data link.
Check the screw for the ECM connectors for correct torque of 5.0 N m (44 lb in).
Check the harness for abrasion and pinch points from the wires that connect the diagnostic connector to the ECM. Expected Result:All connectors, pins and sockets should be completely coupled and/or inserted. The harness should be free of corrosion, abrasion and/or pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - 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 in place and ensure that the connectors are completely coupled.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 2. Determine the Type of Fault in the Data Link
Connect the electronic service tool to the diagnostic connector.
Turn the keyswitch to the ON position. Expected Result:The power lamp should illuminate on the communications adapter. The power lamp on the communications adapter may illuminate when the keyswitch is in any position.Results:
OK - The communications adapter is currently receiving the correct voltage.Repair: If you are redirected to this step from "Check the wiring of the Diagnostic Connector"and if a jumper wire has been installed between pin "A" on the diagnostic connector and the positive terminal on the battery and if a jumper wire has been installed between pin "B" on the diagnostic connector and the negative terminal on the battery, remove the jumper wires and then repair the harness. If the harness cannot be repaired, replace the harness.Proceed to Test Step 5.
Not OK - The communications adapter is not receiving the correct voltage. Proceed to Test Step 3.Test Step 3. Check the Wiring of the Diagnostic Connector

If the communications adapter is connected to the diagnostic connector on the engine, ensure that pin "A" and pin "B" are wired on the engine harness side of the connector. Expected Result:The pins are wired.Results:
OK - The harness is fully wired. Proceed to Test Step 4.
Not OK - The data link connector power connections are not wired.Repair: Fabricate a jumper wire in order to connect pin "A" of the diagnostic connector to +battery and pin "B" to the -battery.Proceed to Test Step 2.Test Step 4. Check the Battery Voltage at the Diagnostic Connector
Turn the keyswitch to the ON position.
Use a multimeter in order to measure the voltage from pin A (+battery) and pin B (ground) of the diagnostic connector. Expected Result:The voltage is between 22.0 Volts DC and 27.0 Volts DC.Results:
OK - The diagnostic connector is currently receiving the correct voltage. Proceed to Test Step 5.
Not OK - The diagnostic connector is not receiving the correct voltage.Repair: Refer to Troubleshooting, "Engine Wiring Information"..Proceed to Test Step 2.Test Step 5. Check the Data Link Connections
Turn the keyswitch to the OFF position.
Disconnect the communications adapter from the diagnostic connector.
Disconnect connector P1 from the ECM. Check the resistance between P1:23 and diagnostic pin "D".
Check the resistance between P1:24 and diagnostic pin "E". Expected Result:The resistance that is measured is less than 10 Ohms.Results:
OK - The resistance is less than 10 Ohms. Proceed to Test Step 6.
Not OK - The resistance is greater than 10 Ohms.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 in place and ensure that the connectors are completely coupled.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 6. Change the Electronic Service Tool Components
If another electronic engine is available, connect the electronic service tool to the other engine. Ensure that the same cables are used.
Turn the keyswitch to the ON position. Determine if the electronic service tool operates correctly on the other engine.
If another engine is not available, obtain a replacement communications adapter and a replacement set of cables. Ensure that the set of cables for the electronic service tool are a complete set.
Install the replacement communications adapter and the set of cables for the electronic service tool and connect to the diagnostic connector.
Turn the keyswitch to the ON position.
If changing the communications adapter or the cables allows the electronic service tool to operate correctly, use the following procedure:
Replace the components from the new set of cables with components from the oldset of cables. Replace one component at a time.
Apply power to the electronic service tool after each of the components is replaced. Use this method to find the faulty component.
If changing the cables does not allow the electronic service tool to operate correctly, connect another electronic service tool.
Turn the keyswitch to the ON position. Expected Result:Result 1 The original electronic service tool works on another engine.Result 2 A different electronic service tool works on the original engine while the engine is being tested.Results:
Result 1 - Proceed to Test Step 7.
Result 2 - Repair: Send the faulty electronic service tool for repairs.STOPTest Step 7. Connect an Electronic Service Tool and the ECM to another Battery
