Typical exampleTest Step 1. Check for Connector Damage
Verify that the circuit breakers are not tripped.
Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Refer to the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connectors that are associated with the circuit.
Check the allen head screw on each ECM connector for the proper torque. Refer to Troubleshooting, "Inspecting Electrical Connectors" for the correct torque values.
Check the harness and the wiring for abrasion and for pinch points.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted, and the harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The connectors and wiring are OK. Proceed to Test Step 2.
Not OK - The connectors and/or wiring are not OK.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 2. Test the Air Shutoff System
Turn the circuit breaker for the battery to the ON position.
Turn the ECS to the STOP position. The engine should be off.
Activate the customer's emergency stop switch.
Monitor the air shutoff solenoids.
Deactivate the customer's emergency stop switch.Expected Result:The air shutoff solenoids activated.Results:
OK - The air shutoff solenoids activated correctly.Repair: The problem may be intermittent. If the problem is intermittent, refer to the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors".STOP
Not OK - The air shutoff solenoids failed to activate. Proceed to Test Step 3.Test Step 3. Check for the Signal from the "ASOS" Switch at the Connector P-C1 for the Power Distribution Panel
Turn the ECS to the STOP position. The engine should be off.
Activate the customer's emergency stop switch.
Monitor the voltage on wire G708 on pin I at connector P-C1 of the rigid harness.
Deactivate the customer's emergency stop switch.Expected Result:The voltage measures 24 3 VDC for approximately 2.5 seconds.Results:
OK - The voltage measures 24 3 VDC for approximately 2.5 seconds. The circuit is operating correctly to this point. Proceed to Test Step 7.
Not OK - The voltage did not measure 24 3 VDC for approximately 2.5 seconds. Proceed to Test Step 4.Test Step 4. Test for Voltage to the Coil of the "ASOS" Switch at the Connector P-C1 for the Power Distribution Panel
Turn the ECS to the STOP position. The engine should be off.
Activate the customer's emergency stop switch.
Monitor the voltage on wire F708 on pin G at connector P-C1 of the rigid harness.
Deactivate the customer's emergency stop switch.Expected Result:The voltage measures 24 3 VDC for approximately one second.Results:
OK - The voltage measures 24 3 VDC for approximately one second. The circuit is operating correctly to this point. Proceed to Test Step 5.
Not OK - No voltage was measured. Proceed to Test Step 14.Test Step 5. Test for Voltage to the Coil of the "ASOS" Switch
Turn the ECS to the OFF/RESET position.
The input to the coil of the "ASOS" switch is wire T708 from the diode assembly. Connect a voltmeter between wire T708 on the "ASOS" switch and the engine ground.Note: The "ASOS" switch is turned on for one second by the ECM. The timer keeps the "ASOS" switch energized for approximately 2.5 seconds.
Turn the ECS to the STOP position. The engine should be off.
Activate the customer's emergency stop switch.
Monitor the voltage on the voltmeter.
Deactivate the customer's emergency stop switch.Expected Result:The voltage measures 24 3 VDC for approximately 2.5 seconds.Results:
OK - The voltage measures 24 3 VDC for approximately 2.5 seconds. The circuit is operating correctly to this point. Proceed to Test Step 6.
Not OK - No voltage was measure
