Coolant Temp Gauge
The PCM controls the coolant temperature gauge by sending gauge position messages to the
BCM over the Class II link based on ECT sensor readings. The BCM averages the temperature over time allowing the gauge to move slowly and remain in a relatively stable position as temperature varies. The BCM then sends the averaged information to the I/P cluster over the link to position the gauge.
