Display information for the Global Positioning System Interface Module (GPSIM).
(1) Cat Data Link Receive Active
(2) Transmit to ECM.
(3) Receive a Signal from the Global Positioning System (GPS Receiver). Test Step 1. Inspect the Electrical Connectors and the Wiring
Turn the keyswitch to the OFF position.
Check the connections to the Electronic Control Module (ECM). Check the ECM connectors, the customer connector, and the wiring for damage or for incorrect attachment.
Check for the correct installation of the wires for the Cat Data Link. Refer to Installation Guide, "Wiring the Cat Data Link" for additional information.
Check the following components for abrasion, corrosion, or incorrect attachment:
Module for the global positioning system
Global Positioning System Interface Module (GPSIM)
Wiring
Verify that each individual ECM is programmed to the proper engine location.
Verify that the negative battery connections at the bus bar are secure and free from corrosion. Expected Result:All connectors, pins and sockets should be completely coupled and/or inserted and the harness and wiring should be free of corrosion, of abrasion, and of pinch points.Results:
OK - The connectors and the harnesses appear to be in good repair. Proceed to Test Step 2.
Not OK - A problem has been found with the harness or with a connector.Repair: Perform the following repair:Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check the Display for Messages
Turn the keyswitch to the ON position.
Verify that each engine ECM is powered up.
Check the display for the GPSIM. Expected Result:The display for the GPSIM illuminates specific segments of the Light Emitting Diodes (LED) in order to display "GPS". Refer to Illustration 1 for the correct display output.Results:
OK - The "GPS" message is displayed correctly. Proceed to Test Step 3.
Not OK - The "GPS" message is not displayed correctly.Repair: The GPSIM is not working properly.Replace the GPSIM.Verify that the repair eliminates the problem.STOPTest Step 3. Check the display on the GPSIM for the Receive Indicator
Turn the keyswitch to the ON position.
Check if the receive indicator is illuminated on the display for the GPSIM. Refer to Illustration 1 . Expected Result:The Cat Data Link's receive indicator on the display for the GPSIM is illuminated.Results:
OK - The receive indicator on the display for the GPSIM is illuminated. The GPSIM is receiving communications from the Cat Data Link. Proceed to Test Step 4.
No - The receive indicator on the display for the GPSIM is not illuminated. The GPSIM is not receiving communications from the Cat Data Link. Proceed to Test Step 5.Test Step 4. Check for Proper Engine OperationUse the keyswitch to start the engine.Expected Result:The engine starts.Results:
OK - The engine started. The engine ECM is receiving power. Proceed to Test Step 7.
Not OK - The engine did not start.Repair: The engine ECM may not be receiving power. Check for battery power to the ECM.
