You can enter the Diagnostic Display mode using the following procedure:
1. Turn the ignition to the "On" position but don't start the engine.
2. Press the "Reset" button on the Driver Information Center (DIC) to turn off any existing warning messages.
3. Press and hold the "Options" button.
4. While holding the "Options" button, press the "Fuel" button four times within a 10-second period.
The onboard diagnostics system will go into the "Automatic" mode, which shows each module's DTCs in a preset sequence:
1. 10 - PCM (Powertrain Control Module)
2. 28 - TCS (Traction Control System)
3. 38 - RTD (Real Time Damping. Some models do not have this option.)
4. 40 - BCM (Body Control Module)
5. 60 - IPC (Instrument Panel Cluster)
6. 80 - Radio
7. 99 - HVAC (Heater Vent-Air Conditioning)
8. A0 - LDCM (Left Door Control Module)
9. A1 - RDCM (Right Door Control Module)
10. AC - SCM (Seat Control Module)
11. B0 - RFA (Remote Function Actuation)For each module, all existing DTCs will be displayed. If no faults are present in a particular module, you'll see "No More Codes" on the IPC display.

Thank you, Exactly what I was looking for. Also today I reset the DIC and the SERVICE ENGINE NOW stayed off and never came back on in a 40 mile trip! Never know when I'll need this!
