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. The SASM sets this DTC if there is excessive resistance or an open in this circuit, including an open fuse.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U3011:13 | Ignition Input Off: Circuit Open | This DTC sets on demand if the ignition voltage supplied to the SASM is below 6 volts for more than one second. |
Possible Causes
- Fuses
- Wiring, terminals or connectors
- SASM-clockspring assembly
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.
