Scan Tool Data Definitions

WARNING: This page is about a different car, the 2003 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

8-Digit GM Part Number: The scan tool displays the 8 digit a numeric module part number.

Battery Voltage: The scan tool displays 0-20 volts. The scan tool displays the voltage as received on the battery positive voltage circuit of the Module or the 72-08 battery voltage message from the dash integration module (DIM) over class 2 line.

Calibration ID: The scan tool displays the Calibration ID number for service identification.

Component Serial No. 8 - 11: The scan tool displays a numeric number. Display indicates digits 8-11 of the component serial number.

Component Serial No. 12: The scan tool displays a numeric number. Display indicates digit 12 of the component serial number.

Component Serial No. 13 - 16: The scan tool displays a numeric number. Display indicates digits 13-16 of the component serial number.

Component Serial No. 17 - 18: The scan tool displays a numeric number. Display indicates digits 17-18 of the component serial number.

Component Serial Number: The scan tool displays an 8 digit a numeric number. Display indicates the first 8 digits of the component serial number.

Ignition 1: The scan tool displays Active/Inactive. Display indicates the status of the discrete ignition positive voltage signal.

Ignition 3: The scan tool displays Active/Inactive. Display indicates the status of the discrete ignition positive voltage signal.

Ignition 3 Input: The scan tool displays Active/Inactive. The scan tool displays Active when the Ignition 3 input (run) circuit of the module receives a battery voltage signal from the ignition switch.

Ignition Accessory: The scan tool displays Active/Inactive. The scan tool displays Active when only the Accessory and unlock circuits of the dash integration module (DIM) receives a battery voltage signal from the ignition switch.

Ignition Counter: The scan tool displays 0-50. The module counts each time the ignition switch is cycled.

Ignition Crank/Run: The scan tool displays Active/Inactive. The scan tool displays Active when the Crank/Run, Run and Unlock circuits of the dash integration module (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 dash integration module (DIM) receives a battery voltage signal from the ignition switch. The scan tool displays Crank when the Crank/Run, 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.

Ignition Unlock: The scan tool displays Active/Inactive. The scan tool displays Active when only the Unlock circuit of the dash integration module (DIM) receives a battery voltage signal from the ignition switch.

Julian Date of Build: The scan tool displays a 3 digit number. An example would be 256. 256 is September 12, which is day 256 based on the Julian Calendar.

Load Reduction Active: The scan tool displays Yes or No. Yes will be displayed when a low battery condition is detected and one or more accessories (blower motor, A/C compressor clutch, etc.) have been disabled in order to reduce the electrical load.

Prom ID: The scan tool displays the PROM ID number for service identification.
