System Faults

There are four conditions which will cause a Tire Pressure Monitoring System fault to be set. All fault codes are associated with a specific wheel location.

1. If the EVIC detects a non-transmitting Sensor/Transmitter in a road wheel for ten consecutive minutes with vehicle speed above 25 MPH (40 kph), it will:
   1. Store an active fault code.
   2. Request a chime.
   3. Display "TIRE SENSOR BAD/MISSING".
   4. Display a dashed line at the wheel location on the graphic display if the display is activated.

   When the EVIC detects:

2. A low pressure sensor battery status,
3. All five sensors transmitting at a shorter than expected interval,
4. Or no valid pressure sensor ID from the spare tire for 20 consecutive ignition cycles spaced at least one hour apart, it will:
   1. Store an active fault code.
   2. Request a chime
   3. Display "TIRE SENSOR BAD/MISSING".

Use the DRBIII® Input/Output function to further isolate the specific concern.

The DRBIII® can be queried to determine the Sensor/Transmitter status:

• "Invalid Pressure" - The Sensor/Transmitter is reporting a negative pressure or a pressure above 434 kPa (63 psi).
• "Low Batt" - The Sensor/Transmitter has reported a low battery status for seven consecutive ignition cycles.
• "Trained" - The Sensor/Transmitter ID code is recognized by the EVIC.
• "Active" - The vehicle is moving at 40 km/h (25 mph) and/or the Sensor/Transmitter is "awake" and transmitting as expected by the EVIC.
