Troubleshooting Test Steps Values Results
1. 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 5 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 2.

2. 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: The linkage is not damaged.
Proceed to Test Step 3.

3. Test the Exhaust Balance Valve Solenoid to Make Sure that the Valve Is Not Stuck in the Closed Position
A. Disconnect hose (7) from the mixer. Refer to Illustration 4.
B. Connect the 215-2592 Wastegate Kit and necessary adapters between hose (7) and the mixer. The other end of hose (7) must stay connected to the inlet of the balance valve solenoid.
C. Turn the keyswitch to the OFF position.
Only apply 138 kPa (20 psi) air pressure to the exhaust balance valve.
D. With gate valve (5) in the open position, regulate the supply air pressure to 138 kPa (20 psi). Make sure gate valve (10) is closed. Once the pressure is stable, close gate valve (5).
E. Loosen fitting (11) for the line from the exhaust balance valve solenoid to the exhaust balance valve.
Valve stuck closed
Result: Air leaked out of the line from the exhaust balance valve solenoid after the fitting was loosened.
The solenoid is not stuck closed. Proceed to Test Step 4.
Result: Air did not leak out of the line from the exhaust balance valve solenoid after the fitting was loosened.
The exhaust balance valve solenoid is not operating properly. Replace the exhaust balance valve solenoid. Return the unit to service.
4. Test the Exhaust Balance Valve Solenoid to Make Sure that the Valve Is Not Stuck in the Open Position
A. Relieve any residual pressure in the system by using gate valve (10) on the wastegate test kit. Once
