Shift Position Indicator

The transmission range sensor (on the valve body) sends a signal to the Transmission Control Module (TCM) on the position of the transaxle manual valve lever. The TCM receives the switch signal and processes the data. The TCM sends the Shift Lever Position (SLP) information to the BCM via the CCD bus. The BCM then outlines the appropriate shifter position indicator in the instrument cluster.
If a problem arises with the shifter position indicator, consult the following chart for diagnostic information. If the malfunction cannot be corrected using the chart, consult the proper diagnostic procedures.
To replace the shifter position indicator, refer to Instrument Panel, Gauges and Warning Indicators.
