here's some copy\paste for you

Computers and Control Systems: Testing and Inspection Procedures Digital Instrument Panel Cluster ENTERING DIAGNOSTICS 1. Turn the ignition switch "ON." 2. Push the "OFF" and "WARM" buttons on the Climate Control Center (CCC) simultaneously and hold until the segment check appears on the Instrument Panel Cluster (IPC). NOTICE: Operating the vehicle in diagnostics for extended time periods without the engine running or without a battery charger will cause the battery to run down and possibly relate false diagnostic information, or cause a "no start" condition. To ensure proper operation, attach a battery charger if vehicle is to be operated in diagnostics without engine running for an extended time period. SEGMENT CHECK The purpose of illuminating the IPC is to verify all segments of the LED displays are working. The turn signal indicators do not light during this check. Further diagnosis should not be attempted unless all segments appear, as this could lead to misdiagnosis. If any portions or segments of the IPC displays are inoperative, the IPC must be replaced. DIAGNOSTIC TROUBLE CODE (DTC) DISPLAY After diagnostics are entered, any DTCs stored in computer memory will be displayed. Each DTC consists of the system abbreviation (P - PCM, IP - IPC, AC - ACM, SD - SIR, TCS -TCS, RS - RSS, PZ - PZM, IR - IRC, RF- RFA, CC - CCP or PH -PHN), a four digit identifier, and the letter C or H. All DTCs for each system are displayed together, in consecutive order by their four digit number (lowest first - i.e. PZ 2016, PZ 2096, etc.). The final digit of the code, a "C" or an "H", is used to indicate whether the DTC is current or history. A "C" means the malfunction was still present the last time the diagnostic test was run, while "H" means the failure was not present the last time the DTC was tested for. If no DTCs are present for a system, a "NO X CODES" message (with X being the system i.e. PCM, IPC, ACM, SIR, TCS, RSS, PZM, IRC, RFA, CCP or PHN) will be displayed. If the communication line to a component is not operating, a "NO X DATA" message will be displayed, indicating that the IPC could not communicate with that system. At any time during the display of DTCs, if the "MODE" button on the IPC is pressed the system will exit "Service Mode" and go back to normal vehicle operation. SELECTING THE SYSTEM After trouble codes have been displayed, a specific vehicle system PCM, IPC, ACP, SIR, TCS, RSS may be selected for testing. The first available system will be automatically displayed (i.e. PCM?). While selecting the system to test, any of the following actions may be taken: 1. Depressing the "HI" button will select the displayed system for testing. 2. Depressing the "LO" button will display the next available system selection. This allows the display to be stepped through all system choices. This list of systems can be repeated following the end of the system list. 3. Depressing the "OFF" button will stop the system selection process and return the display to the beginning of the trouble code sequence. 4. Pressing the "OFF" button twice will return the system to the segment check. SELECTING THE TEST TYPE Having selected a system, the first available test type will be displayed (i.e. PCM DATA?, PCM CLEAR CODES?). While selecting a specific test type, any of the following actions may be taken: 1. Depressing the "HI" button will select the displayed test type. At this point the first of several specific tests will appear. 2. Depressing the "LO" button will display the next available test type for the selected system. This allows the display to be stepped through all available test type choices. This list of test types can be repeated following the display of the last test type. 3. Depressing the "OFF" button will stop the test type selection process and return the display to the next available system selection. CLEAR CODES Selection of "CLEAR CODES?" test will result in the message "CODES CLEARED" being displayed along with the selected systems name. This message will appear for 3 seconds and then return to the next available test type. EXITING DIAGNOSTIC MODE To get out of the diagnostic mode anytime during the test, depress the "MODE" or "DEFOG" button, or turn the ignition switch "OFF." Trouble codes are not erased if this is done prior to selecting "CODES CLEARED."

Im having a problem on my 1997 cutlass supreme v6 3.1L the F flashes 23 times only when i start the car. I used the on-board diagnostic by turning you key to the ON position. With the AC OFF press the "AUTO' and the "OFF" buttons at the same time.
Use the TEMP KNOB to turn through the codes and i got this
-01=09
-02=00
-03=81
-04=00
-05=59
-06=03
-07=-154
-08=01
-09=-154
-10=01
-11=-00
-12=135
-13=00
-14=00
-15=44
-16=-106
-17=196
-18=52
-19=46
-20=-105
-21=88
-22=128

Only thing I could find was the AC is for the ac module, the RF is for the integrated radio, C is current code and H is history code. I couldnt find anything on those specific #s though.
