ŚredniCode U1245 indicates incorrect or missing data for the vehicle interior environment transmitted via the SCP (J1850) bus (Ford).
OBD-II (EN): Invalid or missing interior environment data via SCP (J1850) bus
Code U1245 appears in Fords when one of the modules does not receive correct data about interior temperature or humidity via the SCP (J1850) network. This can cause problems with the air conditioning, heating, or temperature display. Diagnosis requires checking the wires and communication modules – we recommend a visit to a workshop specializing in Ford electrics.
Symptoms
• Incorrect operation of the air conditioning or heating. • Display of incorrect interior temperature values. • Airflow control may operate irregularly. • The check engine light may illuminate.
Possible causes
• Damaged or corroded connectors on the SCP (J1850) bus. • Broken or shorted communication network wires. • Failure of the air conditioning control module (ACM) or interior module. • Fault in the BCM (body control module).
