Circuit Description
The Distance Sensing Cruise Control (DSCC) module monitors the ignition 1 voltage circuit to make sure that the voltage stays within the normal operating range.
DTC Descriptor
The diagnostic procedure supports the following DTCs:
DTC C0800 Device Power 1 Circuit Voltage Below Threshold
The vehicle has DTCs including the DTC symptoms. For more information on DTC symptoms, refer to DTC Symptom Description.
DTC Symptom | DTC Symptom Descriptor |
|---|---|
03 | Voltage Below Threshold |
Conditions for Running the DTC
| • | The ignition switch is at RUN. |
| • | The vehicle drives faster than 40.2 km/h (25 mph). |
Conditions for Setting the DTC
| • | The DSCC module detects that the ignition 1 voltage is below 9.2 volts. |
| • | It lasts for 7 seconds. |
Action Taken When the DTC Sets
| • | DSCC fails. |
| • | Cruise Not Ready indicator illuminates in the driver information center (DIC). |
Conditions for Clearing the DTC
| • | The DTC becomes history when the conditions for setting the DTC are no longer present. |
| • | The history DTC clears after 100 ignition cycles without failure. |
| • | The DSCC module receives a clear code command from the scan tool. |
Diagnostic Aids
Refer to Testing for Intermittent Conditions and Poor Connections.
