Shift Position Indicator

The shift position indicator is located in the instrument cluster. It indicates the position of the manual valve lever by illuminating an LED located under the P, R, N, D, 3, or L gear symbol. The Transmission Range Sensor sends a signal to the TCM on the position of the transaxle manual valve lever. For 1997 and previous, the TCM receives the switch signal and processes the data. The TCM sends the Shift Lever Position (SLP) information to the BCM over the communication bus. The BCM then illuminates the proper LED by sending another signal over the communication bus to the instrument cluster. For 1998, the TCM sends the signal to the BCM and the cluster. The BCM does not operate the cluster.
