High Pressure Monitoring
High pressure monitoring is to indicate high pressure alert. Please note the following
points.
• High pressure alert will be set only when the tyre pressure value goes beyond 48
psi
• High pressure alert in the main alert screen will pop up once for driver notification
when the alert is set and the vehicle is in running condition. Otherwise the alert
will remain in the tyre-tronics screen
• If high pressure value is observed, air has to be released from the respective tyre
until the pressure reaches the placard value of 32 psi
• The vehicle should be driven above 40 kmph for the new pressure value to be
updated and the alert to be cleared
• Once the high pressure alert is triggered the alert shall not get cleared until the
respective tyre pressure is lower than 40 psi
Pressure Leakage Monitoring
Pressure leakage monitoring is to indicate any pressure leakage in any of the vehicle
tyres. Please note the following points.
• The pressure leakage alert will be set only when the tyre pressure is leaking at a
rate greater than 3 psi/minute
• In the pressure leakage condition if the tyre pressure goes too low beyond 24 psi,
then the low pressure alert will be set
• The pressure leakage alert in the main alert screen will pop up once when the
alert is set for driver notification and will be shown in tyre-tronics screen when the
vehicle is in running condition/ignition ON condition
• Once pressure leakage is observed the respective tyre should be observed for air
leakages and the puncture condition has to be rectified. Proper pla-card value
should be filled after puncture rectification
• If the vehicle is running in an extremely rocky and acute bumpy condition then
fluctuating pressure leakage alert may get set which will get rectified when the
vehicle runs back on a normal road. This happens due to sudden change in
pressure levels due to rocky conditions
Auto Spare Tyre Swap Monitoring
Spare tyre swap feature keeps a monitor on the spare tyre if it has been swapped by
the user for any faulty running tyre.
• If any one of the running tyres goes faulty, spare tyre is swapped with the running
tyre and the vehicle is driven, then;
– the system automatically recognizes the swap
– interchanges the running tyre and spare tyre data
Always rectify the faulty tyre either in the spare tyre position or the running tyre
position.
• If the rectified running tyre is replaced back in to running location and the spare
tyre back in the spare position, then it is mandatory that TPMS manual learning is
performed post the rectification
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 20 mins without
signal being received at least once then ‘Communication error’ will be set for
respective tyre position on the infotainment screen. Also the cluster telltale shall
be blinking for 90 secs and there on will remain continuous on
• 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
