Information:
ECM did not detect the open.Repair: Replace the ECM. Refer to Troubleshooting, "Replacing the ECM". Verify that the problem is resolved.STOPTest Step 7. Create a Short Circuit at the Engine Retarder Solenoid
Turn the keyswitch to the OFF position.
Connect the valve cover connector.
Remove the valve cover.
Disconnect the connector on the suspect engine retarder solenoid.
Inspect the terminals on the solenoid connector for damage. Worn terminals and/or damaged terminals on the solenoid connector could cause an intermittent "Open".
Use a jumper wire in order to short the two wires for the suspect solenoid on the solenoid harness connector. Make sure that the solenoid connector securely holds the jumper wire.
Turn the keyswitch to the ON position.
Access the "Special Tests" under the "Diagnostics" menu.Note: The "Retarder Brake Test" will not work if the switch in the cab for the retarder is OFF.
Start the "Retarder Brake Test" on Cat ET.
Once Cat ET displays the status of the engine retarder solenoid, stop the "Retarder Brake Test".
Check for active diagnostic codes and/or logged diagnostic codes that are associated with the retarder solenoids.Expected Result:A high current diagnostic code (-6) is logged.Results:
Yes - A high current diagnostic code (-6) is logged at this time. The harness wiring between the solenoid connector for the suspect engine retarder solenoid and ECM connector P2 is OK.Repair: Temporarily connect a new engine retarder solenoid to the harness, but do not install the new engine retarder solenoid in the engine. Test the solenoid.
