Sensor Signal Missing Alert
When the vehicle is running in speeds between 40 kmph and 120
kmph then the TPMS system should always keep receiving the
signals from all of the running tyres.
• On account of any issue in signal reception or TPMS sensor
damage or tyres changed with out performing manual learning
then the signal will not be received
• Under such condition if the vehicle was driven for more than 15
mins without signal being received at least once, then
‘Communication error’ will be set for respective tyre position on
the infotainment screen. The TPMS cluster telltale is also
illuminated to indicate the same.
• When the TPMS communication error is set then perform
manual learning once. If manual learning is not done successfully
then the corresponding position tyres sensor needs to be
checked by carefully opening the tyre
• If the sensor is found to be damaged then it should be replaced
with a new one and manual learning should be done
Sensor Faulty/ Low Battery Alert
The TPMS sensor in the vehicle tyres has an individual battery
internal to each sensor fixed. If the battery level is too low or the
sensor by itself is malfunctioning then the TPMS system shall give
this alert.
• If the TPMS sensor low battery/faulty is set then the
corresponding position tyres sensor needs to be removed by
carefully opening the tyre and replacing it with a new sensor
• Post replacing the new sensor, manual learning should be done
12.6.6 TPMS Learning
After tyre rotation or TPMS sensor replacement, the receiver must
be learnt, else the TPMS warning lamp indicates a malfunction.
Mandate Points
Manual learning is the process by which the identities of 5 sensors
installed inside the tyres are learnt and programmed in to the
memory of the receiver module.
1. Manual learning should be compulsorily performed on any of
the following conditions or operations done
• Any of the old TPMS sensors are damaged or sensors are
replaced
• Any of the tyres are replaced
• If any of the tyres or set of tyres are shuffled or swapped in
position
• If tyre rotation operation is performed
