The GPS receiver needs to read a minimum of three satellites to function
correctly. In the event that a valid satellite x is not obtained within two minutes
the following message will be displayed:
“GPS SPEED FAIL
NO AUTO
PRESSURE CHANGE”
Also all four keypad LEDs will ash twice, and the ECU willrevert to manual
operation only.
Should this situation occur, you will need to check the GPS receiver connection
to the ECU, ensure that there is a clear view of the sky (as much as practical)
and that the vehicle is not parked in a building. If this does not rectify the issue,
contact your supplier.
Dual Transducer
TractionAir G5 now incorporates “dual transducer technology”. The dual
transducers work in tandem continuously measuring pressure with each other,
they eectively self diagnose. Should either transducer become out of phase with
its partner, the driver is alerted with the ECU displaying the transducer fault.
