Circuit Description
The voltage level is monitored by the dash integration module (DIM) and is sent as a class 2 data message to the instrument panel cluster (IPC). If the DIM loses power the IPC will default to the last voltage level.
Conditions for Running the DTC
| • | The key is in the ON position. |
| • | The engine is running. |
| • | DTC 1327 is not current. |
Conditions for Setting the DTC
This DTC will be set as current when the voltage falls below 10.5 volts for 30 seconds and the engine is running.
Action Taken When the DTC Sets
The charging system indicator message will be set in the driver information center (DIC) W/U50 only.
Conditions for Clearing the MIL/DTC
The DTC clears as a current status when the voltage is greater than 10.5 volts for 30 seconds with the engine running.
