Hybrid warning after aftermarket electrical accessories were fitted

Dash cameras, audio equipment and other additions can change the information a workshop needs when investigating a new warning. The installation date is a useful starting point, not proof of responsibility.

How to approach the assessment

Provide the accessory and installation details and explain whether functions fail together. Do not move power connections or bypass protection devices as an experiment. The assessor can review the installation alongside the vehicle’s existing faults.

Useful details to send

  • Accessory model and installer.
  • Power connection details if documented.
  • Timeline between installation and first symptom.

Arrange the right assessment

This is enquiry guidance, not a high-voltage repair procedure. Do not open battery packs or work on high-voltage equipment. Agree the vehicle assessment and transport arrangements with the receiving workshop first.

Ask AXION about your repair or read our EV and hybrid assessment information. Workshop visits are by appointment in Didcot. Confirm suitability before posting any removed module.
