To help us process your repair accurately and avoid issues:

  • If your part tests good and no fault is found, a $100.00 (for each unit) Bench Test / Diagnostic Fee may apply instead of the repair price.
  • Please select only the issues you are actually experiencing and describe the symptoms in your own words in the “Describe issues with this module” fields.
  • Scan your vehicle for codes before disconnection of battery or removal of unit. If no codes are present, let us know. Any stored or pending codes help confirm the fault and avoid delays in your repair.
  • Selecting the incorrect option here will be corrected on your invoice to the proper amount and will show on your invoice.
