Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the ether injection system.
Check the allen head screw on each ECM connector for the proper torque. Also check the allen head screw on the customer connector for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the harness and the wiring for abrasion and for pinch points from the ether injection solenoid to the ECM. 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 appear to be OK. Proceed to Test Step 2.
Not OK - The connectors and/or wiring are not OK.Repair: Repair the connectors and/or the wiring. Replace parts, if necessary. Verify that the problem is resolved.STOPTest Step 2. Check the Ether Canister for Starting Fluid
Remove electrical power from the ECM.
Remove the ether canister from the ether valve. Determine if the canister contains fluid. Expected Result:The ether canister is not empty.Results:
OK - The ether canister is not empty. Do not install the ether canister. Proceed to Test Step 3.
Not OK - The ether canister is empty.Repair: Replace the empty ether canister with a full ether canister. Verify that the original problem is resolved.Repair CompleteTest Step 3. Check for Active Diagnostic CodesNote: The ether canister must be removed prior to performing this procedure.
Connect Cat ET to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools".
Restore electrical power to the engine ECM.
Proceed to the "Diagnostic Overrides" screen on Cat ET.
Activate the ether injection system. The system will activate for ten seconds.
Monitor the active diagnostic code screen on Cat ET. Check and record any active diagnostic codes. Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Look for a 05 diagnostic code or a 06 diagnostic code.
Remove electrical power from the engine ECM. Expected Result:No diagnostic codes are active.Results:
No active codes - Neither diagnostic code is active.Repair: The problem seems to be resolved. The problem may have been caused by a poor electrical connection. Carefully reinspect the connectors and the wiring. Refer to Troubleshooting, "Electrical Connectors - Inspect".STOP
Not OK - A 05 code is active at this time. The ECM is detecting a low current condition in the circuit. Proceed to Test Step 5.
Not OK - A 06 code is active at this time. The ECM is detecting excessive current in the circuit. Proceed to Test Step 4.Test Step 4. Create an Open at the H
