U1011

What does U1011 mean?

U-code U1011 means "SCP (J1850) Invalid or Missing Data for Engine Air Intake". It is a manufacturer-specific diagnostic trouble code (DTC) in the vehicle network (CAN/LIN bus). A fault has been detected in the scp (j1850) invalid or missing data for engine air intake — the control module has logged this condition during self-diagnostics. This code can be monitored, but service is recommended to prevent escalation. This code applies to OBD-II compliant electric and hybrid vehicles.

Possible Causes

• Damaged CAN or LIN bus wiring
• Faulty or non-responsive control module
• Software or firmware corruption in the module
• Power supply or ground issue at the module

Recommended Actions

1. 1 Note the alert and schedule a diagnostic appointment when convenient
2. 2 Scan for all DTCs with an OBD-II scanner — note any related codes stored alongside U1011
3. 3 Inspect the vehicle network (CAN/LIN bus) component and its wiring for visible damage
4. 4 Check for water intrusion in connector areas and clean contacts if corroded
5. 5 Clear the DTC, road-test the vehicle, and re-scan to confirm whether the fault returns
6. 6 If the fault persists after inspection and clearing, consult an EV-certified technician for component replacement
