1. What does Stop safely and switch off – suspension fault detected mean?

For certain 2022–2023 US Land Rover Range Rover vehicles, this alert has been documented with a suspension warning lamp and stored DTCs including U3000-49. JLR identifies an EESM software calibration error as the cause in the cited service communication.

2. Technical explanation

The verified manufacturer communications describe an instrument-cluster message: “Stop safely and switch off – suspension fault detected.” During diagnosis, U3000-49 may be stored in the Electrical Energy Storage Module (EESM) and Electric Power Inverter Converter Control Module ‘E’ (EPICE). B1646-01 may be stored in the Gateway Module (GWM), and C508D-01 is also reported in the Chassis Control Module B in some cited communications. JLR’s verified cause statement is: EESM software calibration error.

3. What system is affected?

Suspension system / air-suspension warning, with diagnostic references to the EESM, EPICE, GWM, and Chassis Control Module B.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Suspension warning lamp illuminated.
  • Instrument-cluster message: “Stop safely and switch off – suspension fault detected.”
  • U3000-49 stored in the EESM and EPICE during TOPIx Cloud diagnosis.
  • B1646-01 stored in the GWM.
  • C508D-01 stored in Chassis Control Module B, as reported in some cited communications.

6. Possible causes

  • EESM software calibration error, according to JLR’s SSM75970 manufacturer communication.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?
