Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Overhead Console: Troubleshooting: Temperature
The CMTC receives PCI bus messages from the BCM for all displayed information except the compass display. If a dash (-) is displayed, the CMTC is not receiving a PCI bus message from the BCM. To diagnose the PCI bus line and the BCM, see BODY CONTROL MODULES - CONCORDE, INTREPID & 300M article.
If the CMTC displays a temperature more than 130°F (54°C), check for a short circuit between the temperature sensor and the BCM. If the CMTC displays a temperature less than -67°F (-40°C), check for an open circuit between the temperature sensor and the BCM.
