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 Circuit for the Customer's Remote Emergency Stop
Turn the circuit breaker for the battery to the ON position.
Turn the ECS to the STOP position.
Activate the customer's remote emergency stop switch.
Monitor the air shutoff solenoids.
Deactivate the remote 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 Power Distribution Panel
Turn the ECS to the STOP position.
Activate the remote emergency stop switch.
Monitor the voltage on wire G708 on pin I at connector P-C1 of the rigid harness.
Deactivate the remote 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 Relay "R4A" at the Power Distribution Panel
Turn the ECS to the STOP position.
Activate the remote emergency stop switch.
Monitor the voltage on wire 354 on pin B at connector P-C2 of the rigid harness.
Deactivate the remote emergency stop switch.Expected Result:The voltage measures 24 3 VDC.Results:
OK - The voltage measures 24 3 VDC. The circuit is operating correctly to this point. Proceed to Test Step 5.
Not OK - No voltage was measured. Proceed to Test Step 11.Test Step 5. Test for Voltage at 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 terminal 6 of the timer. Connect a voltmeter between wire T708 on the "ASOS" switch and the engine ground.
Turn the ECS to the STOP position.
Activate the remote emergency stop switch.
Monitor the voltage on the voltmeter.
Deactivate the remote 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 - The voltage did not measure 24 3 VDC. Proceed to Test Step 8.Test Step 6. Check for Voltage from the "ASOS" Switch to the Air Shutoff Solenoids
Turn the ECS to the OFF/RESET position.
Disconnect wire G708 from the "ASOS" switch.
Connect a voltmeter to the empty terminal on the "ASOS" switch. Connect the other lead from the voltmeter to engine ground.
Turn the ECS to the STOP position.
Activate the remote emergency stop switch.
Monitor the voltage on the voltmeter.
Deactivate the remote emergency stop switch.
Reconnect wire G708 to the "ASOS" 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.Repair: Repair the wire G708 between the "ASOS" switch and wire G708 on pin I at connector P-C1 of the rigid harness.STOP
Not OK - The voltage did not measure 24 3 VDC for approximately 2.5 seconds.Repair: Verify that 24 3 VDC is present on wire K708 at the normally open contacts of the "ASOS" switch. If voltage is not present on wire K708, check the wire K708 and the circuit breaker for the air shutoff for problems. If voltage is present on the wire K708, check wire 220 on the coil of the "ASOS" switch for continuity to the −Battery. If necessary, repair the wire or replace the wire. If wire 220 is OK and voltage is present on wire K708, replace the "ASOS" switch.STOPTest Step 7. Check the Voltage at the Connector for the Air Shutoff Solenoids
Turn the ECS to the OFF/RESET position.
Disconnect the connector for the air shutoff solenoids. Disconnect the connector for the right and left sides of the engine.
Connect a voltmeter between wire G708 on the connector for the air shutoff solenoid and the engine ground.
Turn the ECS to the STOP position.
Activate the remote emergency stop switch.
Monitor the voltage on the voltmeter.
Deactivate the remote emergency stop switch.
Reconnect the connectors for the air shutoff solenoids.Expected Result:The voltage measures 24 &plus
