Vehicle Speed Sensor (VSS) Adaption (As Of 2/98)
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2000 Mercedes-Benz ML320, 2000 Mercedes-Benz E320, 2000 Mercedes-Benz CLK320, 2000 Mercedes-Benz C280, and 1999 Mercedes-Benz ML320. 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 3, increase engine speed to approximately 2100 RPM, then hold a 50 percent engine load for approximately 30 seconds. Using scan tool, verify VSS adaptation has occurred.
