Information:
Use this procedure for the following diagnostic trouble codes:
Table 1
Diagnostic Codes
CDL Code and Description Comments
791-5
Compression Brake Low/High Solenoid #1 : Current Below Normal The code is logged when there is an electrical or wiring problem with the brake assemble positioned over cylinder 3 and cylinder 4.
791-6
Compression Brake Low/High Solenoid #1 : Current Above Normal The code is logged when there is an electrical or wiring problem with the brake assemble positioned over cylinder 3 and cylinder 4.
792-5
Compression Brake Medium/High Solenoid #1 : Current Below Normal The code is logged when there is an electrical or wiring problem with the brake assembles positioned over cylinders 1 and 2 or cylinders 5 and 6.
792-6
Compression Brake Medium/High Solenoid #1 : Current Above Normal The code is logged when there is an electrical or wiring problem with the brake assembles positioned over cylinders 1 and 2 or cylinders 5 and 6.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Turn the keyswitch to ON.
C. Access the diagnostic overrides under the "Diagnostics" menu.
D. Start the "Compression Brake Low/High Override".
E. Once Cat ET displays the status of the compression brake solenoid, stop the "Compression Brake Low/High Override".
F. Monitor the "Active Diagnostic Code" screen on Cat ET. Record any active diagnostic codes.
G. Start the "Compression Brake Med/High Override".
H. Once Cat ET displays the status of the compression brake solenoid, stop the "Compression Brake Med/High Override".
I. Monitor the "Active Diagnostic Code" screen on Cat ET. Record any active diagnostic codes.
Codes
Result: A 791-5, or 792-5 diagnostic code is active.
Proceed to Test Step 2.
Result: A 791-6, or 792-6 diagnostic code is active.
Proceed to Test Step 4.
2. Create a Short Between the Wires of the Suspect Compression Brake Solenoid at the Valve Cover Connector
Note: To troubleshoot a 791-5 diagnostic code, use the "Compression Brake Low/High Override" in Cat ET. To troubleshoot a 792-5 diagnostic code, use the "Compression Brake Med/High Override" in Cat ET.
A. Turn the keyswitch to OFF.
B. Disconnect the harness at the valve cover connector.
C. Fabricate a jumper wire to create a short between the supply wire for the suspect compression brake solenoid and engine ground.
D. Turn the keyswitch to ON.
E. Access the diagnostic overrides under the "Diagnostics" menu.
F. Start the override for the compression brake.
G. Once Cat ET displays the status of the compression brake solenoid, stop the override.
H. Monitor the "Active Diagnostic Code" screen in Cat ET. Record any active diagnostic codes.
I. Turn the keyswitch to OFF. Remove the jumper wire.
Note: A -5 open circuit diagnostic code will be active for the other compression brake solenoid. Ignore the diagnostic codes for the other compression brake solenoid. Ignore any diagnostic codes for the injector solenoids.
Short circuit
Result: A 791-6, or 792-6 diagnostic code is active. The harness wiring is OK.
Proceed to Test Step 3.
Result: A 791-5, or 792-5 diagnostic code is active.
Repair: Repair the harness or replace the harness.
