The addition of the OEM Calibration Requirements Search to the RTS portal was a big step for the collision industry. While this new feature has been well received, there has been some confusion about what is included in the search tool. OEM Calibration Requirements Search is designed to provide information on the calibration requirements that are needed for vehicles equipped with advanced driver assistance systems (ADAS). This includes systems such as adaptive cruise control, lane keep assist, and collision braking.

It does not include occupant classification systems (OCS), steering angle sensors, battery disconnects, or other calibrations/initializations required, when not related directly to ADAS. Let’s take a look at what additional items may require calibrations/initializations on Toyota and Lexus vehicles.

Toyota and Lexus provide a list of items that require calibrations, when they are required, and what may fail if the calibration is not performed. This list can be found in the vehicle-specific repair manuals, under the General tab. A few of the systems that may require calibrations are as follows:

• Steering sensor
• Sliding moon roof
• Power door windows
• Occupant Classification System
• Parking Assist Monitor System
• Power Door Lock Control System
• Air Conditioning System
• Power Back Door System

(Note this is not a complete list and can vary by model)

Problems with the electrical system may not be obvious. Per Toyota CRIB #191: “Considering the fact that a capable scan tool is the only way to identify some DTCs, Toyota requires that repairers perform a “Health Check” diagnostic scan if a vehicle has sustained damage as a result of a collision that may affect electrical systems.” The CRIB also states that: “Not all DTCs illuminate a MIL (Malfunction Indicator Light).”

There are many more systems that may need to be calibrated after removal or a collision. Always refer to Toyota/Lexus service information for the most up-to-date CRIB information. Make sure to check the repair manual to know what systems may be affected by the repairs that you are performing, to help ensure a complete, safe, and quality repair.
