My odometer, temp and direction dont display. The baclight comes on when headlamos are on but I have no display day or night. When this started I also noticed that my door locks seem to keep locking usually as I start from a stopped position
Do you
have the same problem?

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 utilizes 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 the powertrain control module (PCM), 4x4 control module, and the anti-lock brake system (ABS) module. Communication using the UBP network utilizes 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 MODULE COMMUNICATIONS NETWORK.
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 CAN or UBP communication network to another module.
Which module controls the output of the feature.

The autolock feature locks all the doors when all the doors are closed, the brake pedal is pressed with the key in the ON position, and vehicle speed then exceeds 8 km/h (5 mph) or higher. This feature relocks the doors (if any doors were open) after the brake pedal is pressed, once all the doors are read as closed and vehicle speed then exceeds 8 km/h (5 mph). Door ajar switches are wired directly to the vehicle security module. The autolock feature can be enabled/disabled through module configuration, the ignition switch, and the keyless entry keypad. The auto-lock feature also uses inputs from the key position, the brake pedal position (BPP) switch and vehicle speed through the universal asynchronous receiver-transmitter (UART)- based protocol (UBP) network.
