P006E

P006E-TURBOCHARGER BOOST CONTROL MODULE SUPPLY VOLTAGE CIRCUIT LOW





For a complete wiring diagram Refer to Diagrams/Electrical.

Theory of Operation


The variable geometry turbocharger (VGT) is electronically activated by the VGT actuator. The VGT actuator is a smart device and receives information via the J1939 datalink from the ECM. The VGT actuator performs its own diagnostics and reports failures back to the ECM using the J1939 datalink. The ECM then decodes the error message and converts it to a fault code. The ECM will not light a MIL lamp for this fault. When this fault is active the VGT will still continue to respond to commands from the ECM.

- When Monitored:
Ignition on.

- Set Condition:
Supplied voltage to the VGT actuator dropped below 10 volts.







Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Initial Inspection and Diagnostic Overview


Diagnostic Test


1. INFORMATION ONLY
Turn the ignition on.
With the scan tool, read DTC's.
Is P006E active?

Yes


- The VGT actuator power supply has dropped below 10 volts. This fault code is for information only and will not light the MIL lamp. Erase DTC.


No


- Repair complete, erase DTC's.
