Vehicle Speed Sensor (VSS) Adaption
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2000 Mercedes-Benz SLK230, 2000 Mercedes-Benz C230, 1999 Mercedes-Benz SLK230, 1999 Mercedes-Benz C230, and 1998 Mercedes-Benz SLK230. However, it is still accessible from the selected car via links, so may be relevant.
After replacing an Engine Control Module (ECM), Crankshaft Position (CKP) sensor, starter ring gear or motor mount, sensor adaptation must be performed. Run engine until coolant temperature is more than 158°F (70°C). Drive vehicle. With gear selector in position 4, increase engine speed to approximately 2500 RPM, then coast until engine speed is less than 1500 RPM. Change gear selector to position 2. Increase engine speed to approximately 6100 RPM, then coast until engine speed is less than 4100 RPM. Again increase engine speed to approximately 6100 RPM, then coast until engine speed is less than 3000 RPM. Using scan tool, verify VSS adaptation has occurred.
