Scan Tool Data Displays - IPC

IPDO1: This code displays the value (A/D count) for the dimming potentiometer on the headlamp switch. This value ranges from 0-155 under normal operation. Higher values (200 and above) may indicate a malfunction in the circuit.

IPDO2: BATTERY VOLTS is displayed in volts between 8.7-18.0 on IPC connector C1 terminal A1 and terminal B1 (Controlled Power).

IPDO3: The VEHICLE SPEED is shown in miles per hour between 0-255.

IPDO4: The LOW BRAKE FLUID signal is shown in volts between 0-5 V.
^ Approximately 2.5 V indicates that the brake fluid level is correct.
^ Less than 1 V indicates a low brake fluid condition or a short to ground in the low brake fluid switch circuit.
^ More than 4 V indicates an open in the low brake fluid switch circuit.

IPDO5: This code displays the value (A/D count) of the steering wheel control switches at IPC connector C2 terminal B11. Refer to Entertainment in order to decode which one of the 8 functions is requested. The value may range from 0-255. Radio/Stereo

IPDO6: The code displays the current PASSKey(R) II pellet value (A/D count) being detected at IPC connector C1 terminal A10. The value may range from 0-255. A display of 0 indicates that an invalid key code is present.

IPDO7: The TWILIGHT DELAY POTENTIOMETER displays the current value (A/D count) being detected at connector C1 terminal C9. The value may range from 0-255. This count value represents the 0-180 second twilight delay.

IPDO8: The TWILIGHT PHOTOCELL displays the current value (A/D count) being detected at connector C1 terminal C12. This value is used in order to determine the exterior light/dark status. Dark is normally a value above 143. Light is normally a value below 123.

IPDO9 to IPD13: These codes display the current EEPROM data values for options A-E. The values reflect the decimal equivalent of an 8-bit binary code. The values may range from 0-255. No units are associated with these numbers. In order to decode these values, refer to IPC Output Overrides - overrides IPS01-IPS05.

IPD14: The IGNITION CYCLE COUNTER displays a value that is the number of times that the IPC was turned OFF since an IPC DTC was last detected. After 50 ignition cycles without any malfunctions being detected, all IPC DTCs are cleared.

IPD98: The DCP SOFTWARE VERSION is the software ID for an IPC microprocessor.

IPD99: The CPM SOFTWARE VERSION is the software ID for an IPC microprocessor.
