Equinox AWD V6-3.4L VIN F (2006)
Odometer: Description and Operation
ODOMETER
The odometer shows how far the vehicle has been driven, in either miles (domestic) or kilometers (export). The odometer is shown on display when any
of the following occur:
-
Ignition is in ACC
-
Ignition is in RUN, with no messages on
-
The trip reset stem is pressed with the ignition OFF
Odometer readings are displayed in the IPC based on a class 2 message from the BCM. The PCM calculates the distance traveled from the vehicle speed
sensor (VSS) input. The BCM receives a CAN serial data message from the PCM and stores the current mileage.
The IPC stores the last valid odometer reading from the BCM in non-volatile memory. When a new valid odometer reading is received from the BCM,
the IPC will update the display and store the new reading.
The IPC also receives class 2 messages from the BCM regarding VIN and Vehicle content information. Valid information is stored in non-volatile
memory at the first key-up with a new IPC. If the VIN or option content do not match the stored information, the odometer will display ERROR.
TRIP ODOMETER
Trip odometer readings are calculated by the IPC based on the odometer reading received through a class 2 message from the BCM. The trip odometer is
shown when selected with the odometer trip reset stem. To reset the trip odometer, press and hold the trip reset stem for about two seconds, until the trip
odometer shows zero.
