Turbocharger Compressor Bypass Valve Actuator : Current Above Normal The applicable Electronic Control Module (ECM) monitors the current flow through the coils of the applicable components.The applicable ECM sets a diagnostic trouble code if the current flow through a coil is incorrect. These codes can be activated only when the applicable ECM is sending a command to the control valves. A -5 code indicates that the current flow through the circuit is low and there is an open in the circuit. A -6 code indicates that the current flow through the circuit is high and there is a short in the circuit.Engine Exhaust Gas Recirculation (EGR) Valve Control refers to the NOx Reduction System (NRS) Valve.Engine Exhaust Gas Recirculation (EGR) Valve 2 Control refers to the Exhaust Restriction Valve (ERV).Electrical Checkouts on the Cat® Electronic Technician (ET)

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: A -5 code is active or logged.
Proceed to Test Step 2.
Result: A -6 code is active or logged.
Proceed to Test Step 3.
2. Check the Wiring for an Open Circuit
A. Verify that the harness connector is free of debris, free of corrosion, and securely connected.
B. Disconnect the solenoid from the harness.
C. Connect a jumper wire between the terminals of the harness connector for the affected coil. The coil is replaced with a short circuit.
Create a Short
Result: A -5 code became active during the electrical checkout. The ECM did not detect the jumper wire. There is an open circuit in the wiring between the coil and the ECM connector. There may be a problem with a connector.
Repair: Repair or replace the connectors or the wiring.
Verify that the repair eliminated the problem.
Result: A -6 code is activated during the electrical checkout. The ECM detected the jumper wire. There is a problem with the solenoid.
Repair: Replace the solenoid.
Verify that the repair eliminated the problem.
3. Check the Wiring for a Short Circuit
A. Disconnect the solenoid from the harness.
Create an Open
Result: A -6 code became active during the electrical checkout. The ECM did not detect the open circuit. There is a short circuit in the wiring between the coil and the ECM conne
