the suspect compression brake solenoid.
Inspect the terminals on the connector for the compression brake solenoid for damage.
Fabricate a jumper wire in order to short the two wires for the suspect solenoid on the solenoid connector. Crimp a pin to each end of the jumper wire.
Make sure that the solenoid connector securely holds the jumper wire. Note: Worn terminals and/or damaged terminals on the solenoid connector could cause an intermittent "Open".
Turn the keyswitch to the ON position.
Access the diagnostic override under the "Diagnostics" menu.
Start the override for the compression brake.
Once Cat ET displays the status of the compression brake solenoid, stop the override.
Monitor the active diagnostic code screen on Cat ET. Check and record any active diagnostic codes.
Turn the keyswitch to the OFF position. Remove the wire short. Expected Result:A 791-6 diagnostic code or a 792-6 diagnostic code is active at this time.Results:
OK - A 791-6 diagnostic code or a 792-6 diagnostic code is active at this time. The harness wiring between the connector for the compression brake solenoid and the ECM is OK.Repair: Temporarily connect a new compression brake solenoid to the harness, but do not install the new compression brake solenoid in the engine. Retest the circuit for the compression brake solenoid. Verify that there are no active diagnostic codes for the compression brake solenoid. If there are no active diagnostic codes for the compression brake solenoid, permanently install the new compression brake solenoid.STOP
Not OK - A 791-5 diagnostic code or a 792-5 diagnostic code is active at this
