SEAL KIT- 1469860 - Caterpillar

Use this procedure to solve communication problems between the electronic service tool and the Electronic Control Module (ECM). The electronic service tool must communicate with the ECM on the Cat data link and the J1939 data link.Indicators on the communication adapter indicate that communication is occurring on a particular data link. The "J1939 / DeviceNet" indicator indicates that the communication adapter is communicating on the J1939 data link. The "J1708" indicator indicates that the communication adapter is communicating on the Cat data link. The electronic service tool displays a message during the connection if the electronic service tool cannot communicate on both data links.The following conditions can cause a communication problem:
Incorrect communication adapter
Incorrect version of the electronic service tool
Incorrect firmware in the communication adapter
Incorrect configuration of the electronic service tool
A fault in the electrical power to the communication adapter
A fault in the electrical power to the engine ECM
A fault in the wiring for a data link
A fault in the electrical cables between the PC and the machine

Troubleshooting Test Steps Values Results
1. Determine the Fault
A. If an indicator other than the "POWER" indicator is illuminated when the electronic service tool is not communicating with an ECM, disconnect and reconnect the communication adapter. Communication problem Result: Both indicators on the communication adapter are not flashing.
Proceed to Test Step 2.
Result: The electronic service tool indicates that the engine is serviced on both links.
Proceed to Test Step 2.
Result: The electronic service tool displays a message that indicates the firmware in the communication adapter does not support communication on both data links.
Proceed to Test Step 3.
Result: The electronic service tool displays an Error" #142 The interface hardware is not responding" message.
Proceed to Test Step 3.
Result: The electronic service tool indicates that the electronic service tool cannot find an exact match for the software version in the ECM.
Repair: Update the electronic service tool to the latest available version.
Result: The power indicator is not illuminated.
Proceed to Test Step 5.
2. Verify that the Correct Communication Adapter is Being Used
A. A 317-7484 Communication Adapter Gp must be used to with a 370-4617 Cable As (USB) and a 457-6114 Cable As (Datalink Cable CA3) to communicate.
The following communication adapters cannot be used because the communication adapters do not communicate over both data links:
1. Wireless communication adapter
2. 7X-1701 Communication Adapter As
B. Determine the communication adapter that is being used.
Communication Adapter Result: An incorrect communication adapter is being used.
Repair: Connect a correct communication adapter. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
Attempt to establish communication. Continue with this procedure if the communication adapter does not communicate on both data links.
Result: A correct communication adapter is being used. However, the "Power" indicator is not illuminated.
Proceed to Test Step 5.
Result: A correct communication adapter is being used. The "Power" indicator is illuminated.
Proceed to Test Step 4.
3. Check the Version of the Firmware for the Communication Adapter
The version of the firmware for the communication adapter must be "1.18.47" or higher.
A. Electronically disconnect the electronic service tool. Verify that
