### Conditions for Running the DTC

The IPC must have normal operationg battery voltage.

### Conditions for Setting the DTC

The IPC detects that the trip reset switch input is low (grounded) for greater than 60 seconds.

### Action Taken When the DTC Sets

The IPC will disable (ignore) the trip reset switch.

### Conditions for Clearing the DTC

• | A current DTC B2823 will clear after a complete ignition cycle.

• | A scan tool may be used to clear the DTC.
