Normal Operation and Fault Conditions
The SASM requires an operating voltage between 8 and 17 volts. The SASM receives fused ignition voltage from the BCM run-start bus and fused battery voltage from the BJB. The SASM has a single ground circuit. The SASM sets this DTC if there is excessive resistance or an open in one or more of these circuits, a discharged battery or an inoperative charging system.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U3003:1C | Battery Voltage: Circuit Voltage Out of Range | This DTC sets in continuous memory if the voltage supplied to the SASM is below 8 volts for more than one-half second. |
Possible Causes
- Fuses
- Wiring, terminals or connectors
- SASM-clockspring assembly
