Pinpoint Test K : U3003:62 - SASM (Steering Angle Sensor Module): Notes
Refer to Cruise Control for schematic and connector information.
Normal Operation and Fault Conditions
The SASM receives battery voltage from the BCM and has a single ground circuit located in the instrument panel wiring harness. Excessive resistance or an open in one or both of these circuits, a discharged battery, an inoperative charging system or an overcharging condition in the charging system results in the SASM setting a DTC.
This DTC may also set in the SASM due to battery charging or vehicle jump starting events.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U3003:62 | Battery Voltage: Signal Compare Failure | This DTC sets when the voltage received by the SASM falls below 6 volts or raises above 21 volts. |
