Detail: My F150 2005 truck will not show my millage/trip millage. This has been an intermittant problem in the recent past, but always came back after a short time. But now I have lost the millage indicator all together, and it fails to return. What can cause this problem?
Solution: Change the instrument cluster or have your's repaired . The instrument cluster is a configurable, hybrid electronic cluster (HEC) that contains a microprocessor, gauges, indicator lamps, and internal circuitry. The instrument cluster is non-repairable with the exception of the instrument cluster lens and indicator bulbs. The instrument cluster uses hardwired circuitry, the controller area network (CAN) and the universal asynchronous receiver transmitter (UART)-based protocol (UBP) communication networks. Communication using the CAN transmits and receives data between the instrument cluster and the powertrain control module (PCM), and the anti-lock brake system (ABS) module. Communication using the UBP network uses data transmitted and received by the instrument cluster, and the electronic automatic temperature control (EATC), vehicle security module, and the driver seat module. The restraint control module (RCM) and the parking aid module communication is on the international standards organization (ISO) network. For additional information regarding the CAN, UBP and ISO communication networks, refer to Section 418-00 . It is very important to understand: where the input originates from. all the information necessary in order for a feature to operate. which module(s) receive(s) the input or command message. whether the module which received the input controls the output of the feature, or whether it outputs a message over the communication network to another module. which module controls the output of the feature. Instrument Cluster Module Configuration When installing a new instrument cluster, the instrument cluster must be configured. For additional information, refer to Section 418-01 . The instrument cluster is a configurable, hybrid electronic cluster (HEC) that contains a microprocessor, gauges, indicator lamps, and internal circuitry. The following items must be configured when installing a new instrument cluster: vehicle security module outside air temperature outside air temperature settings (°C/°F) compass climate control (manual or electronic) belt minder speedometer overspeed warning your best bet , take it to a qualified repair shop.

Please visit my website for complete repair information. www.kincerservice.com Thanks Mike , Are you sure the coolant isn't heating up? I had the same issue once and the problem was i hadn't opened the high point vent on the cooling system. there for no liquid was getting to the sensor ie. it wasn't reading the true temp of the coolant. If that's not it try pulling the sensor out get enough slack in the wiring so you can get the sensor into a small pan of water. put scalding hot/boiling water in the pan have someone watch the guage put the business end of the sensor into the water and see if your temp rises. If not you were ether given the wrong sensor or a defective one. , Sounds like there is a bad connection, (positive or negative) From battery, Check and clean all connections. If wires and connections are good check for loose wires or fuses at fuse block.
