5276-5
Engine Exhaust Manifold Bank #1 Flow Balance Valve Actuator Control : Current Below Normal 3409-5
Engine Exhaust Manifold Bank #1 Flow Balance Valve Solenoid : Current Below Normal The Electronic Control Module (ECM) detects a low current in the circuit for the balance valve solenoid.
5276-6
Engine Exhaust Manifold Bank #1 Flow Balance Valve Actuator Control : Current Above Normal 3409-6
Engine Exhaust Manifold Bank #1 Flow Balance Valve Solenoid : Current Above Normal The ECM detects a high current in the circuit for the balance valve solenoid.
5276-7
Engine Exhaust Manifold Bank #1 Flow Balance Valve Actuator Control : Not Responding Properly E1123 (1)
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. The balance valve actuator and balance valve solenoid are integral components. The valve is designed with a normally open position. As the solenoid is energized, the valve is closed. Air flow to the diaphragms of the balance valves at the turbochargers is restricted. The valve vents residual air pressure that is in the air lines to the atmosphere.To test the balance valve actuator, a test apparatus that consists of the following tooling will be required:

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Determine if a code is active or logged.
Codes
Result: Codes E1123 (1) or 5276-7 are active or logged. Or no codes are active for the balance valve solenoid currently, but operation of the balance valve actuator is suspect.
Proceed to Test Step 2.
Result: A 3409-5 is active or logged. There is a low current in the circuit for the balance valve solenoid.
Proceed to Test Step 9.
Result: A 3409-6 is active or logged. There is a high current in the circuit for the balance valve solenoid.
Proceed to Test Step 8.

Troubleshooting Test Steps Values Results
2. Inspect the Air Lines from the Balance Valve Actuator to the Balance Valves at the Turbochargers
A. Inspect the air lines from the outlet of the balance valve actuator to the inlet of each of the balance valves. Check the lines for any signs of leakage.
Leakage
Result: The lines are not damaged. All the line fittings are clean and tight.
Proceed to Test Step 3.
Result: Damage to the lines is discovered.
Repair: Repair the line or replace the line. Return the unit to service.
Verify that the repair eliminated the problem.

3. Inspect the External Linkage for the Balance Valves at each Turbocharger
A. Inspect the balance valve linkage from each of the canisters to the housing. Also, inspect the connection point from the canister to the valve. Inspect the linkage for the following issues.
Dirt buildup
Rubbing
Damage
External Linkage
Result: The linkage is not damaged.
Proceed to Test Step 4.
Result: The linkage is damaged.
Repair: Replace the turbocharger. Return the unit to service.
If the problem is not resolved, proceed to Test Step 4.
