Pinpoint Test A : U3003:16: Notes
Refer to Vehicle Dynamic Suspension for schematic and connector information.
Normal Operation and Fault Conditions
The VDM requires an operating voltage that is between 9 and 16 volts. The VDM receives this voltage from the BCM. The VDM has a single ground circuit. Excessive resistance or an open in one or more of these circuits, a discharged battery or a inoperative charging system results in the VDM setting a DTC.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U3003:16 | Battery Voltage: Circuit Voltage Below Threshold | This DTC sets in continuous memory and on-demand if the voltage supplied to the VDM falls below 9 volts for more than 5 seconds. |
Possible Sources
- Fuses
- Wiring, terminals or connectors
- VDM
Visual Inspection and Diagnostic Pre-checks
- Make sure the vehicle battery terminals and cables are free of any corrosion and other contaminants.
- Make sure the vehicle battery terminals are tightened to their correct torque specifications.
- Make sure BCM fuse 36 (15A) is OK.
