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 looses power the IPC will failsoft to the last voltage level.
Conditions for Running the DTC
| • | The key is in the ON position. |
| • | The engine is running. |
Conditions for Setting the DTC
This DTC will be set as current when the voltage is greater than 16.2 volts for 30 seconds with the engine running.
Action Taken When the DTC Sets
The charging system telltale and driver warning message will be set in the drivers information center (DIC).
Conditions for Clearing the MIL/DTC
The DTC clears as a current status when the voltage falls below 16.2 volts for 30 seconds with the engine running.
Step | Action | Values | Yes | No |
|---|---|---|---|---|
1 | Did you perform the Engine Electrical Diagnostic System Check? | -- | Go to Step 2 | |
2 |
Does the scan tool indicate that the volts parameter is within the specified range? | 10.5-16.2 V | Go to Step 3 | Go to Charging System Test |
3 | Replace the IPC. Refer to Instrument Cluster Replacement in Instrument Panel, Gages, and Console. Did you complete the replacement? | -- | Go to Step 4 | -- |
