Cluster Switches

The odometer/trip odometer display is mounted on a separate board attached to the main display board. The odometer displays the total vehicle mileage up to 999,999 miles in the English mode. If the mileage exceeds this, the display flashes ERROR. In the Metric mode, the display will flash ERROR when it exceeds 999,999 kilometers. The English display will still show the normal display.

The display can be switched from total odometer to trip odometer by pushing the TRIP button. When the switch is open, the total mileage is displayed. When the TRIP switch is closed, the trip mileage is displayed. This signal is sent to the cluster through the LT GRN (226) wire. When the TRIP switch is closed (trip mileage) the LT GRN (226) wire is connected to ground through the BLK (150) wire at the switch assembly.

The trip odometer can be reset to 0 by pushing the RESET button. This momentarily connects the LT GRN/BLK (376) wire to the BLK (150) wire at the switch assembly. The display must be in the TRIP mode to be reset.

The accumulated mileages of the two displays are stored in a non-volatile memory chip to prevent losing this data if the battery or cluster is disconnected.

If the cluster is replaced, the Odometer Display can be transferred to the new cluster.

The entire cluster is replaced as a unit. There are no dealer replaceable parts within the cluster. If there is a condition in the Digital Cluster, the whole cluster is removed and exchanged.
