Module recently replaced, or fitted as a used unit, and not yet programmed or configured for the vehicle; Interrupted or failed software update or reprogramming, leaving calibration data incomplete or corrupt; Outdated or incorrect calibration loaded in the module; Low battery voltage or a power supply interruption during programming or start-up corrupting stored data; Poor power, earth or data connections causing the module to reset or fail its self-check; Internal module fault such as memory failure.

5: AreaNetwork area 5
10: FaultThe specific fault in that area

What it means

U3510 means a control module has detected that its calibration data is missing, not programmed or not valid. The module runs a self-check at start-up and found no usable calibration, or the data failed an integrity check. Which module sets the code, and what it affects, depends on the vehicle and the module that stored it.

Symptoms

Warning lamp on, such as engine, airbag, ABS or a general fault light, depending on the module affected
Engine will not start, or runs in a reduced-performance (limp) mode
Function controlled by the affected module is disabled or behaves erratically
Other modules log communication faults with the affected module
Code returns straight after clearing

Possible causes

Module recently replaced, or fitted as a used unit, and not yet programmed or configured for the vehiclelikely
Interrupted or failed software update or reprogramming, leaving calibration data incomplete or corruptlikely
Outdated or incorrect calibration loaded in the modulepossible
Low battery voltage or a power supply interruption during programming or start-up corrupting stored datapossible
Poor power, earth or data connections causing the module to reset or fail its self-checkpossible
Internal module fault such as memory failurerare

How to diagnose

Read all stored codes and freeze frame data, noting which module stored U3510 and whether other codes are present
Find out whether any module has recently been replaced, repaired or reprogrammed, or whether the battery was disconnected or went flat
Check battery condition and charging voltage, as low voltage can corrupt module data and cause false faults
Inspect the affected module's connectors, wiring, fuses and earths for damage, corrosion or looseness
Check for other communication or module fault codes that could point to a wiring or network issue
Check the manufacturer's service information for software or calibration updates and technical bulletins for that model and module
Confirm the module part number and software version match the vehicle's specification
Clear the code and retest to see whether it returns immediately or only after a particular event

How to fix

Programme or flash the module with the correct, current calibration for the vehicle using approved procedures, with a stable power supply during the process
Complete any required configuration, coding or learn procedure after fitting a replacement module
Repair or replace damaged wiring, connectors, fuses or earth connections
Restore the battery or charging system to good condition before reprogramming
Replace the module if it cannot accept a valid calibration or has an internal fault, then programme it to the vehicle

Can I keep driving?

Medium severity

Whether it is safe to drive depends on which module is affected. If the car starts and runs normally with no safety-related warnings, drive carefully and get it checked soon, but stop and seek help if the car goes into limp mode or an ABS, airbag or steering warning is showing.
