Scan Tool Data Definitions

8 Digit GM Part Number - The scan tool displays a 8 digit alphanumeric number. This is the modules part number.

Battery Voltage - The scan tool displays 0-30 Volts. The voltage measured between the module's battery positive voltage circuit and ground circuit.

Calibration ID - The scan tool displays a 4 digit alphanumeric number. This number designates the modules calibrations.

Ign. Accessory - The scan tool displays Active/Inactive. The scan tool displays Active when only the Accessory and Unlock circuits of the DIM receives a battery voltage signal from the ignition switch.

Ignition Crank/Run - The scan tool displays Active/Inactive. The scan tool displays Active when the Crank/Run and Unlock circuits of the DIM receives a battery voltage signal from the ignition switch.

Ign. Run - The scan tool displays Active/Inactive. The scan tool displays Active when the Run, Accessory, Run/Crank and Unlock circuits of the DIM receives a battery voltage signal from the ignition switch.

Ignition Switch - The scan tool displays Accy./Crank/Off/RAP/RAP-Unlock/Run/Unlock. The scan tool displays Accy. when the accessory and Unlock circuits of the DIM receives a battery voltage signal from the ignition switch. The scan tool displays Crank when the Crank/Run, and Unlock circuits of the DIM receives a battery voltage signal from the ignition switch. The scan tool displays Off when none of the power moding circuits of the DIM receive a battery voltage signal from the ignition switch. The scan tool displays RAP (Retained Accessory Power) when RAP is active and none of the power moding circuits of the DIM receive a battery voltage signal from the ignition switch. The scan tool displays RAP-Unlock when RAP is active and the Ign. Unlock circuit of the DIM receives a battery voltage signal from the ignition switch. The scan tool displays Run when all of the power moding circuits of the DIM receive a battery voltage signal from the ignition switch. The scan tool displays Unlock when the Unlock circuit of the DIM receives a battery voltage signal from the ignition switch.

Ign. Unlock - The scan tool displays Active/inactive. The scan tool displays Active when only the Unlock circuit of the DIM receives a battery voltage signal from the ignition switch.

Jullian Date of Build - The scan tool displays 3 digit numeric number. This is the day of the year that the module was built.

PROM ID - The scan tool displays a 4 digit alphanumeric number. This is modules internal PROM identification number.
