Tire Pressure Monitoring System (TPMS)

The central electronic module (CEM) can store diagnostic trouble codes (DTCs) if there is a fault in the receiver or a fault in any of the sensors. In order to carry out a correct evaluation of the function, the vehicle must have traveled faster than 40 km/h (25 mph) for longer than 570 seconds (approximately 9.5 minutes). This time is accumulated time, i. e. the time is interrupted if the vehicle drops below 40 km/h (25 mph), if stopping at traffic lights for example. Counting continues as soon as the vehicle exceeds 40 km/h (25 mph) again.

The central electronic module (CEM) can store two diagnostic trouble codes (DTCs) per sensor. A diagnostic trouble code (DTC) for lost communication when traveling, a diagnostic trouble code (DTC) for low battery voltage and a diagnostic trouble code (DTC) when a learned sensor is not obtained during the current operating cycle. Diagnostic trouble codes (DTCs) are also stored if the configuration of the system is not carried out, fails or is interrupted.

When a diagnostic trouble code (DTC) is stored, the ID number of the sensor that applies to the diagnostic trouble code (DTC) is also stored. When a diagnostic trouble code (DTC) is stored, a message is shown in the driver information module (DIM).
