Schematic diagram of the output for the warning lampThe engine is equipped with a remote control panel.Test Step 1. Inspect the Electrical Connectors and the Wiring
Set the engine control to the OFF/RESET mode. Remove the electrical power from the engine.Note: For the following steps, refer to Troubleshooting, "Inspecting Electrical Connectors".
Thoroughly inspect each of the following connectors:
EIS connectors on the control module
Connections for the equipment that is connected to the output for the warning lamp
Illustration 3 g01047061
Harness side of the EIS connector (EISC-C) Output for the warning lamp
Perform a 45 N (10 lb) pull test on each of the wires that are associated with the output for the warning lamp.
Check the terminal strips for corrosion and for mechanical failure.
If the engine is equipped for CSA, check the harnesses and the wiring for abrasion and for pinch points between the device that is connected to the output and the control module.Expected Result:The connectors, pins, and sockets are connected properly. The terminal strips do not have corrosion or mechanical failure. The connectors and the wiring do not have corrosion, abrasion, or pinch points.Results:
OK - The components are in good condition with proper connections.
Not OK - The components are not in good condition and/or at least one connection is improper.Repair: Perform the necessary repairs and/or replace parts, if necessary.STOPTest Step 2. Check for an Open Circuit
Disconnect the EIS connector.
At the output device, identify the wire that runs to the EIS control module. Disconnect the end of the wire from the device. This will isolate the wire.
Check the continuity of the wiring between terminal EISC-C and the end of the wire that was removed from the output device.Expected Result:The wiring has continuity.Results:
OK - The wiring has continuity.Repair: Perform the following procedure:
Check the continuity of the output device. If the output device does not have continuity, replace the output device. STOP.
Check the continuity of the wiring between the output device and +Battery. If the wiring does not have continuity, repair the wiring or replace the wiring. STOP.
Reconnect the end of the wire to the output device. Restore electrical power to the engine and check the operation of the output for the warning lamp. If the output operates correctly, the problem is resolved. STOP. If the output does not operate correctly, proceed to Test Step 3.
Not OK - The wiring does not have continuity.Repair: Repair the connection and/or the wire, when possible. Replace parts, if necessary. Verify that the problem is resolved.STOPTest Step 3. Check for a Short Circuit
Verify that electrical power is removed from the engine.
Verify that the EIS connector is disconnected.
At the output device, identify the wire that runs to the EIS control module. Disconnect the end of the wire from the device. This will isolate the wire.
Measure the resistance between terminal EISC-C and all of the other terminals on the EIS connector.Expected Result:All of the measurements indicate an open circuit.Results:
OK - All of the measurements indicate an open circuit.Repair: Perform the following procedure:
Check the output device for a short circuit. If the output device has a short circuit, replace the output device. STOP.
If the output device does not have a short circuit, reconnect all of the wiring and the connectors.
Restore the electrical power to the engine. Determine if the problem is resolved. If the problem is resolved, STOP. If the problem is not resolved, proceed to Test Step 4.Test Step 4. Perform a Self Test of the EIS Control Module
Perform the self test for the EIS control module. Refer to Troubleshooting, "Control Module Self Test".Expected Result:The self test was successful.Results:
OK - The self test was successful.Repair: If the problem persists, refer to Troubleshooting, "Inspecting Electrical Connectors".STOP
Not OK - The self test was not successful.Repair: Perform the corrective action that is appropriate for the fault. Refer to Troubleshooting, "Control Module Self Test". Verify that the original problem is resolved.STOP
