Troubleshooting tips

Troubleshooting tips when activating a TPMS sensor on a Mercedes-Benz

• Try deflating the tire by 10 PSI. On some models for the Mercedes-Benz, manufacture years 2000-2006, TPMS sensors may not activate unless pressure drops at least 10 PSI.
• Be sure to hold to the tool above the valve stem on the sidewall of the tire for the most accurate signal reading. Note that some oversized aftermarket wheels may cause signal interference. 
• If there are issues activating the sensor, with an error “no signal detected”, the wrong frequency may have been selected on the tool, or the wrong sensor frequency was installed in the wheel.
