Circuit Description
The instrument panel cluster (IPC) monitors the signal circuit of the internal trip odometer reset switch in order to change odometer displays and to reset the odometer value. The IPC detects a switch activation when the signal circuit is low.
DTC Descriptors
This diagnostic procedure supports the following DTCs:
| • | DTC B2823 Trip Odometer Reset Switch Circuit Low |
| • | DTC B3574 Trip Odometer A or B (trip odometer 1 or 2) Select Switch Circuit Low |
Conditions for Running the DTC
The IPC must have normal operating battery voltage.
Conditions for Setting the DTC
The IPC detects that the trip odometer reset switch signal circuit is low for greater than 60 seconds.
Action Taken When the DTC Sets
The IPC ignores the trip odometer reset switch signal circuit. The IPC sets DTC B2823.
Conditions for Clearing the DTC
| • | A history DTC B2823 will clear after a complete ignition cycle. |
| • | The IPC receives the clear code command from the scan tool. |
Diagnostic Aids
| • | The IPC will store the code as current only as long as the failure exists. An intermittent failure will be stored as a history DTC B2823. |
| • | If DTC B2823 is set only in history, press and release the trip reset switch several times in order to verify the customer concern. |
