Circuit/System Description
The instrument cluster displays the travelled distance based on the information from the engine control module (ECM). The ECM converts the data from the vehicle speed sensor to a distance signal. The ECM sends the distance information via a High Speed CAN-Bus signal to the body control module (BCM). The BCM then sends the information via a Low Speed CAN-Bus signal to the instrument cluster to display the vehicle odometer and trip odometer. The instrument cluster detects the activation of the trip reset switch and a press and hold of the trip reset switch resets the trip odometer information to zero.

Circuit/System Verification
Ignition ON, verify the odometer trip reset switch resets the trip odometer display when the switch is pressed.
| ⇒ | If the odometer trip reset switch does not reset the trip odometer, replace the P16 Instrument Cluster. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
