DTC U1096: Class 2 TXD Failure (Failed To Transmit 3 Times): Description

Instrument cluster uses an oscillator to send and interpret data between other components on class 2 serial data line. It sends or receives different bytes of information between instrument cluster and other vehicle components. When vehicle is first turned on, an internal test is performed by instrument cluster to determine if oscillator is operating properly.

DTC U1096 will set when oscillator is disrupted by outside radio frequency interference. When DTC U1096 is set, SERVICE VEHICLE SOON indicator light will illuminate.

Under all fault conditions, a current DTC U1096 requires an ignition cycle to become a history code. If conditions for malfunction no longer exist, history DTC will clear after 100 consecutive ignition cycles. DTC U1096 will also clear when scan tool is used to clear codes.
