Tire Pressure System Test
STANDARD PROCEDURE - TIRE PRESSURE SYSTEM TESTThe following test can be used to verify two functions. One, that the tire pressure sensors are transmitting properly and two, the EVIC module is receiving these transmissions accordingly
1. Retrain the tire sensors. The tire sensors must be retrained in order to set the proper transmitting time cycle (twice a minute), failure to retrain the sensors will cause a much slower transmitting time cycle (once a hour).
2. Using the STEP button on the overhead console, scroll to the blank display, then press the RESET button for five seconds, a beep will sound indicating the start of this test. The vehicle icon and transmission counters will now be displayed, (same display as individual tire pressure except counters replace tire pressure values).
3. Upon entering the test mode, the EVIC will clear the sensor counter and each time a sensor signal for a road tire is received, the EVIC will update the counter value (vehicle must be driven at 25 mph to transmit). The counter values should all read the same value. If any of the road tires indicate a different value than another tire sensor, this is a sign of a problem. Replace the appropriate tire sensor and retest the system. This test will continue until any of the overhead console buttons are pressed or the ignition is turned off.
NOTE: Pressing the RESET button during the test will sound a beep and reset all the counter values back to zero.
