Car Chip Vehicle Conflicts & Exclusions

Car Chip has been carefully designed and tested to comply with OBDII protocols J1850-41.6, J1850-10.4, ISO9141, KWP2000 (ISO14320), and CAN (ISO 11898), which are used on most cars and light trucks sold in the USA, model-year 1996 or later. However, some vehicle models are not in full compliance with these protocols. In addition, the computer control systems on a given vehicle may be malfunctioning or out of spec, as may be the sensors used by these systems.

Before installing Car Chip, be sure to review the list of known exclusions, conflicts, and anomalies below. Unless specified otherwise, the list applies to all versions of the Car Chip.

This list is current to the best of our knowledge as of the time of publication. However, given the thousands of vehicle models produced since 1996, no list can be completely comprehensive.

While our testing and the experience of thousands of Car Chip users have shown the unit to be safe and reliable, there is an inherent risk in adding any aftermarket product that may potentially affect the operation or drivability of your vehicle. Should you be concerned about the operation of your vehicle at any time while using Car Chip, you should pull over off the roadway immediately or as soon as it is safe to do so. Remove Car Chip from the OBDII port and consult a licensed mechanic or automobile service center.

List of Conflicts & Exclusions

Tiptronic ® Transmissions – Car Chip may cause vehicle hesitation or stuttering when used in 2003 or earlier model-year vehicles with Tiptronic transmissions. Developed by Audi and included on many of their vehicles, a Tiptronic transmission is one in which the driver may switch from a manual transmission to an automatic transmission while driving. Please check your vehicle’s owner’s manual to see if your vehicle has a Tiptronic transmission. We have not resolved this issue, and we recommend that you not use Car Chip in vehicles with Tiptronic transmissions.

Using Car Chip with Other Aftermarket Products – Car Chip may not operate properly or may cause unexpected vehicle behavior if it is used in conjunction with other aftermarket products that also use the ODBII port or communicate with the vehicle’s on-board computers. Examples of these include remote starters, keyless entry systems, and some alarm systems. If you are using any of these aftermarket products, we recommend that you remove them from your vehicle before using Car Chip.

Vehicles Manufactured for Sale Outside the US & Canada – While vehicles manufactured for sale outside the US and Canada may appear to have an ODBII port, they may not use the same protocols, and thus may not be compatible with Car Chip. For vehicles manufactured for sale in Europe, some 1996–1999 vehicles may be compatible; most 2000 and later vehicles should be compatible. Since requirements vary by country, vehicles manufactured for sale elsewhere in the world may or may not be compatible.
