OBD-II (EN): Fuel System Data Invalid or Missing on SCP (J1850) Bus
Code U1130 signals a communication problem on the SCP (J1850) network – the system is not receiving correct data regarding the fuel system. The cause could be a damaged wiring harness, connector corrosion, or a faulty control module. Professional diagnosis using a workshop scanner is recommended to precisely locate the source of the fault.
Symptoms
Check engine light (MIL) on; possible engine performance problems (rough running, hard starting); reduced engine power; problems with the fuel management system may occur; in some cases, failure of communication modules (e.g., CD changer).
Possible causes
• Damaged or intermittent SCP (J1850) communication bus – short circuit, open circuit, or corrosion in the wiring harness • Faulty control module (PCM, ECM, or other network node) not responding to requests for fuel system data • Corroded or loose electrical connectors on the CAN/SCP network • Defect of the communication module itself (e.g., CD changer module or other network node) • Power supply or ground disturbances of the network modules (poor grounding, low voltage)
