For starting-authorisation problems, first investigate the key, power supply, communication and control-unit identification. Requests are accepted only from verifiably authorised owners or workshops. Describe the fault and any unit replacement. No bypass instructions are provided.
A fault code starts a diagnosis; it does not prove a software fault. Send vehicle details, the complete fault code and your findings. We assess the available readout and the options for the specific ECU or TCU.
What do we need?
- Record make, model, year, engine, ECU/TCU identification, complete fault codes and previous work.
- Use a suitable programming tool and retain the current or original readout. Specify Master or Slave configuration and the reading method.
- We assess the file information and discuss options, costs and required activations. You carry out the work and final checks.
