Normal Operation
DTC B2844 is a continuous memory DTC that sets in the instrument cluster if the instrument cluster senses voltage on the START/RUN input circuit CBP29 (WH/VT) without an interrupt between ignition switch positions or if ignition START or RUN is sensed without a key-in-ignition message from the smart junction box (SJB).

Possible Causes
- Circuitry
- Ignition switch
- Instrument cluster
