ENTERING DIAGNOSTICS
1. Turn the ignition switch "ON."
2. Push the "OFF" and "WARMER" buttons on the CCC (Digital IPC) or the "OFF" and "PASSENGER WARMER" buttons on the CCP (analog IPC) simultaneously and hold until the segment check appears on the 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.

STATUS LIGHTS
While in Service Diagnostics, the displays on the CCC (Digital IPC) or CCP (analog IPC) may be used to indicate the status of various inputs and operating conditions. The meaning of each word or symbol on the panel will change depending on which system is selected.

SELECTING THE SYSTEM
After DTCs have been displayed, a specific vehicle system (PCM, IPC, ACM, SIR, TCS, RSS, PZM, IRC, RFA, CCP or PHN) may be selected for testing, although not all systems will Allow more than retrieving DTCs.

The first available system will be automatically displayed (i.e. "IPC? "). While selecting the system to test, any of the following actions may be taken:
^ Pressing the "HI" button will select the displayed system for testing.
^ Pressing 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.
^ Pressing the "OFF" button will stop the system selection process and return the display to the beginning of the trouble code sequence.
^ 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 (e.g. "PZM DATA?"). While selecting a specific test type, any of the following actions may be taken:
^ Depressing the "HI" button will select the displayed test type. At this point the first of several specific tests will appear.
^ 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.
^ Depressing the "OFF" button will stop the test type selection process and return the display to the next available system selection.
