Scan Tool Data Definitions
- 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.
