3 Theory of Operation The Variable Geometry Turbocharger (VGT) is electronically controlled by the Electronic Turbo Actuator. The Electronic Turbo Actuator is a smart device; it communicates information with the Powertrain Control Module (PCM) over the J99 BUS. The Electronic Turbo Actuator performs its own internal diagnostics and reports failures back to the PCM. The PCM then decodes the error message and converts it to a fault code. The PCM lights the Malfunction Indicator Lamp (MIL) after the diagnostic runs and fails in two consecutive drive cycles. The PCM will turn off the MIL immediately after this diagnostic runs and passes in four consecutive drive cycles. When Monitored: With the ignition on. Set Condition: The Electronic Turbo Actuator does not receive a valid J99 BUS message from the Powertrain Control Module (PCM) for five seconds. Possible Causes VOLT ELECTRONIC TURBO POWERTRAIN CONTROL MODULE (PCM) Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 8 - DTC-Based Diagnostics/ Diagnostic Test. OTHER DTCs. Ignition on, engine not running.. With the scan tool, read DTCs. Is U00C active? Yes Perform the Diagnostics for U00C first. No Go To. POWERTRAIN CONTROL MODULE. Disconnect the Electronic Turbo Actuator harness connector. NOTE: Check connectors - Clean/repair as necessary.

4 . Ignition on, engine not running.. After 75 seconds, monitor the system response with the scan tool. Is U00C active? Yes Go To No Replace the Powertrain Control Module in accordance with the Service Information.. INTERMITTENT CONNECTION. Reconnect the Electronic Turbo Actuator harness connector.. Ignition on, engine not running.. After 75 seconds, monitor the system response with the scan tool. Is P006 active? Yes Go To No Perform the INTERMITTENT CONDITION - 6.7L diagnostic procedure. (Refer to 8 - DTC-Based Diagnostics/. PCM CONNECTION. Disconnect the PCM harness connector. NOTE: Check connectors - Clean/repair as necessary. Were their any dirty or damaged terminals? Yes Repair/Replace as necessary. No Go To 5 5. INTERMITTENT CONNECTION. Reconnect the Electronic Turbo Actuator harness connector.. Reconnect the PCM harness connector.. Ignition on, engine not running. 5. After 75 seconds, monitor the system response with the scan tool. Is P006 active? Yes Replace the Electronic Turbo Actuator in accordance with the Service Information.(Refer to 09 - Engine, 6.7L Diesel/Turbocharger System/, Turbocharger/Removal)

5 No Perform the INTERMITTENT CONDITION - 6.7L diagnostic procedure. (Refer to 8 - DTC-Based Diagnostics/ 5
