Symptom Related Diagnostic Procedures

The Transmission Range Sensor (TRS) 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 Body Control Module (BCM) via the Chrysler Collision Detection (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 chart above for diagnostic information. If the malfunction cannot be corrected using the chart, refer to Transmission Control Systems/System Diagnosis.
