Business Sectors (Suites): Vehicle Fitting
Developed by: IMI
Approved on: 31 Dec 2021


This standard is about recalibrating sensors in Advanced Driver Assistance Systems (ADAS) following removal and replacement of vehicle units/panels to facilitate vehicle fitting activities.

ADAS includes systems for driver safety, pedestrian safety, motion/stability control and collision avoidance systems.

Scope Performance

Scope Knowledge





​This section contains examples and explanations of some of the terms used but does not form part of the standard.

Agreed timescales
Examples include manufacturers’ recommended work times, job times set by the company or a job time agreed with the customer.

Collision avoidance system
For example, forward collision warning, surround view sound, night vision, lane departure warning, AEB (Autonomous emergency braking), adaptive cruise control and stability control.

Driver safety
For example, night vision, glare-free high beam and pixel light, automatic parking, blind spot monitor, driver drowsiness detector, driver monitoring system, traffic sign recognition.
