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.

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. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
