Typical engine components for the Cat Data Link (1) J61 customer connector (2) J60 connector for the electronic service tool (3) J1/P1 connectors
Thoroughly inspect connectors (1), (2) and (3). Inspect all of the other connectors that are associated with the circuit for the Cat Data Link. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Verify that the wiring for the Cat Data Link is installed correctly. Refer to Special Instruction, REHS1187, "Electronic Installation Guide" for additional information.
Check the following components for abrasion, for corrosion, or for incorrect attachment.
Global Positioning System Interface Module (GPSIM)
Engine Vision Interface Module (EVIM)
Engine Vision Display
EMCP 3 (GSC)Ensure that the 163-3973 Cable is securely connected to the EVIM and to the Engine Vision Display.
Verify that each individual ECM is programmed to the proper engine location.

Perform a 45 N (10 lb) pull test on each of the wires that are associated with the Cat Data Link.
Check the allen head screw on each ECM connector for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the allen head screw on the customer connector for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the wiring harnesses for abrasion, for corrosion and for pinch points.Expected Result:All connectors, pins and sockets are completely coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - The harness and wiring appear to be okay. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or the wiring.Repair: Repair the connectors and/or the wiring. Replace parts, if necessary. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled. Verify that the problem is resolved.STOPTest Step 2. Check the Wiring at each Module
Turn the keyswitch to the ON position.
Measure the supply voltage between terminals B+ and B− at each interface module in order to verify that the modules are receiving the correct operating voltage.
Verify that each wire of the Cat Data Link is connected to the correct terminal on each interface module.Expected Result:The voltage measurement at each interface module is between 11.0 VDC and 13.5 VDC for a 12 volt system and between 22.0 VDC and 27.0 VDC for a 24 volt system. The wires for the Cat Data Link are connected correctly.Results:
OK - The wiring at each module is installed correctly. Proceed to Test Step 3.
Not OK - The wiring at a module is not installed correctly.Repair: Make the necessary repairs. Verify that the repair eliminates the problem.STOPTest Step 3. Check for a Short Circuit
Turn the keyswitch to the OFF position.
Disconnect the wiring for the Cat Data Link from the EVIM the GSC,and the GPSIM.
Disconnect the P1 and P2 connectors from the ECM.
Measure the resistance between the points that are listed in Table 1. Be sure to wiggle the wires in the harnesses as you make each resistance measurement.
Table 1
Resistance Measurements for the Wiring Harness    
Connector and Terminal    Terminal    
P1-8 (Cat Data Link +)     All of the other terminals on the P1 connector    
All of the terminals on the P2 connector
Engine ground
P1-9 (Cat Data Link −)     All of the other terminals on the P1 connector    
All of the terminals on the P2 connector
Engine ground Expected Result:All of the resistance measurements indicate an open circuit.Results:
OK - All of the resistance measurements indicate an open circuit. Proceed to Test Step 4.
Not OK - At least one resistance measurement does not indicate an open circuit. There is a problem with a wiring harness. There may be a problem with a connector.Repair: Repair the wiring and/or the connector. Replace parts, if necessary. Verify that the problem is resolved.STOPTest Step 4. Check for an Open Circuit
Turn the keyswitch to the OFF position.
Disconnect the P1 ECM connector.
Use a jumper wire to create a short circuit between terminals P1-8 a
