Frequently asked questions
Choosing a product
How do I choose the correct module?
Start with the exact make, model, generation and production year on the product page. The instrument cluster and connector version also matter. Registration year alone may not identify the correct version.
If you are unsure, email the product link and vehicle details to support@carelectronicslab.com before ordering.
What is the difference between Short and Long versions?
These are physical product variants. Select the version that matches the connector and installation requirements of your vehicle. Do not choose by price alone or assume that one version adds operating modes.
The selected variant’s price is shown on its product page. Confirm the required version with support if the connector is unclear.
Are the same modes available on every vehicle?
No. The number of modes, recording percentages, switching controls and confirmation signals depend on the product and firmware. Use the operating-mode cards on the exact product page as your reference.
Modes and operation
What do FREEZE, LIMITED and BYPASS mean?
FREEZE is described as 0% distance recording. LIMITED records the approximate percentage stated on the product page. BYPASS allows normal distance recording.
For example, a 10% recording mode represents approximately 10 km recorded over a 100 km test. Not every product offers all three mode types.
Will the speedometer show actual speed?
Check the “Speedometer displays” section on the selected product page. Where it states “Actual speed displayed”, the speed display remains at actual speed in the listed modes. Distance recording and speed display are separate specifications.
How do I switch modes and recognise confirmation?
Follow the exact switching sequence on your product page. Some modules use high-beam flashes; others also support a vehicle button. The number of inputs and allowed timing differ.
Read the separate indication description: confirmation may use hazard indicators or another dashboard signal. Do not use another model’s instructions.
Does the module remember its mode after power-up?
Check the product’s “Startup mode” section. A module may start in FREEZE or BYPASS after power-up; you should not assume that the last selected mode is saved.
Is a phone app or Bluetooth required?
Use the controls described on the product page. App control or Bluetooth should only be expected when explicitly listed for that exact product. A vehicle-button switching sequence does not require a phone app.
What is the intended use?
The mileage-control products in this catalogue are presented for controlled off-road and dynamometer testing. Keep accurate records of test distance and do not use a module to misrepresent a vehicle’s mileage or history.
Installation and support
Can I follow a general installation guide for every model?
No. This website’s installation overview explains preparation and checks. Connector position, trim removal and electrical procedures must come from instructions for the exact vehicle and module. Use a qualified installer if you are not familiar with the vehicle’s electrical system.
What should I do if a warning appears or switching does not work?
Stop the test and record the warning, selected mode and switching sequence. Check the product instructions and ask support for help before continuing. Do not keep driving with an unexpected warning or repeatedly clear fault codes without recording them.
See the support checklist for the details to send.
Where can I check delivery, returns and warranty information?
Review the available delivery options and charges at checkout and the terms supplied with your order. For a destination-specific delivery estimate, a return request or a warranty question, email support with the product or order number. Contact support before sending a product back.
Before you order
Ask us to help identify the correct product or physical version. Include your vehicle details and the product link so the request can be checked against the listing.
Ask about compatibilityAfter you order
For installation questions, product behaviour, delivery or a return enquiry, include your order number and describe what you need help with.
Request order supportWhat to include in a technical request
- Product: product link, selected version and order number, if available.
- Vehicle: make, model, generation, production year and cluster type.
- What happened: the selected mode, switching sequence and confirmation signal.
- Evidence: the exact warning text, relevant fault codes and clear photos of the module or connector, where useful.
- Timing: whether the issue appeared on installation, after power-up or during a test.
Keep personal documents, passwords and payment-card details out of your message. Share vehicle or connector photos only where they help explain the issue.
Checks before continuing a test
Mode does not change
Recheck the listed input count and timing for that product. Note whether any confirmation appeared and tell support exactly what sequence you used.
Unexpected dashboard warning
Stop testing and record the warning and any fault codes. Avoid repeated resets or further wiring changes while the cause is unclear.
Different startup behaviour
Compare what happens after power-up with the product’s startup-mode section. Some modules deliberately start in FREEZE; others start in BYPASS.
Connector does not match
Do not force the connection or alter the wiring. Send a clear photo and the selected product version to support.
