Troubleshooting and Valve Stem Pin

Sensor Failure

Failure Code         

Failure Analysis

E-01  

Monitor has lost contact of a sensor for over 20 minutes. The possible
reason is the sensor is damaged or low on battery.

E-02   

Sensor self-monitoring failure.

E-03  

Sensor measurement (pressure or temperature ) range exceeded.

Monitor Failure

If the monitor doesn’t turn on, check if the power cable is connected properly, and the vehicle's cigar
lighter socket power is on. Otherwise, the cable or the monitor itself might be damaged. 

Note: Please contact your dealer for replacement sensor, monitor or cable.

Valve Stem Pin

Be sure to inspect and replace any defective, corroded or cracked valve stems before installing the
sensors. If replacements are necessary we suggest replacing the valve stems with a metal type stem.
This improves the life of the stem due to premature failure from drying out and cracking of inferior
manufactured stems. 
The valve stem pin at each tyre position should now be checked to see if it is in the correct position to
allow the sensors to be activated by the air pressure from the tyres. 

Valve Stem Pin Misalignment:

 If the valve stem pin is set too deep or off centred, the valve stem pin

will not make good contact with the sensor pin plunger, resulting in an incorrect or no resulting pressure
reading. Use a valve stem tool to adjust the pin out far enough to allow the pin tool to release air from the
valve stem. The pin should not be extracted to the point that air is released all the time from the valve
stem. This should be checked with the aid of a small amount of soapy water for air leaks. 

Good Condition

Pin Misalign

Corroded
