CDL Code J1939 Code Code Description
(code descriptions may vary) Comments
E1123 (1) 5276-7 Engine Exhaust Manifold Bank #1 Flow Balance Valve Not Responding to Command The engine ECM determines when conditions are adequate to open the exhaust balance valve. Also, the engine ECM determines when conditions are adequate to close the exhaust balance valve. The engine ECM monitors the NRS gas flow to determine if the exhaust balance valve reacted as commanded. If the NRS gas flow does not match the desired rate, the fault is logged.
E1123 (2) 5276-7 Engine Exhaust Manifold Bank #1 Flow Balance Valve Not Responding to Command The engine ECM determines when conditions are adequate to open the exhaust balance valve. Also, the engine ECM determines when conditions are adequate to close the exhaust balance valve. The engine ECM monitors the NRS gas flow to determine if the exhaust balance valve reacted as commanded. If the NRS gas flow does not match the desired rate, the fault is logged. Engine power is derated.
Follow the troubleshooting procedure in order to identify the root cause of the problem.

Troubleshooting Test Steps Values Results
1. Check for Diagnostic Trouble Codes
A. Establish communication between Caterpillar Electronic Technician (ET) and the Electronic Control Module (ECM) . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Determine if a code is active or logged.
Diagnostic Trouble code
Result: An E1123 or 5276-7 code is active or logged.
Proceed to Test Step 2.

2. Inspect the Air Lines from the Exhaust Balance Valve Solenoid to the Exhaust Balance Valve Actuator
Inspection of the air lines is difficult in some applications. Test Step 6 will provide further testing procedures.
A. Inspect the air lines from the outlet of the exhaust balance valve solenoid to the inlet of the exhaust balance valve actuator. Inspect the lines for any signs of leakage.
Damaged air line
Result: A line is damaged.
Repair the line or replace the line. Return the unit to service.
Result: A line is not damaged.
Proceed to Test Step 3.

Troubleshooting Test Steps Values Results
3. Inspect the Linkage to the Exhaust Balance Valve
A. Inspect the linkage to the exhaust balance valve from the canister to the housing. Also, inspect the connection point from the linkage to the valve. Inspect the linkage for the following issues:
1. Bending
2. Breakage
Damaged or broken linkage
Result: The linkage is damaged.
Replace the turbocharger. Return the unit to service.
Result: A linkage is not damaged.
Proceed to Test Step 4.
