Calibrating (Adaptation) Without Diagnostic Tools
A special test drive can be carried out as an alternative to using VIDA (Volvo scan tool) for calibration. Two basic requirements needed in order to carry out the calibration is that the lateral acceleration whilst driving must not be too high (no sharp turns) and the road surface must be even, smooth (no potholes, grooves etc) and not slippery.
- Erase diagnostic trouble codes (DTCs). Certain diagnostic trouble codes (DTCs) corresponding to calibration cannot be erased until calibration has been successfully carried out
- Drive the car a distance of 30 km (18.64 miles) with regard to the above requirements. Calibration (adaptation)has been carried out 100% after driving the recommended distance. Driving a distance of 10 km (6.21 miles) gives a calibration of up to 75-80%. Calibration is not cancelled if diagnostic trouble codes (DTCs) are stored, which means that the test drive can continue
- Return to the workshop and read off the diagnostic trouble codes (DTCs). Calibration has been successful if no diagnostic trouble codes (DTCs) have been stored
- If diagnostic trouble codes (DTCs) have been stored again, erase the diagnostic trouble codes (DTCs) and test drive again.
