Go to the DTC 85 troubleshooting See: 85.?
NO -
Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit See:

8. Turn the ignition switch to LOCK (0).
9. Turn the ignition switch to ON (II).
10. Check TPMS DATA LIST for RF, LF, RR, or LR TIRE PRESSURE SENSOR SIGNAL STATUS changing to NORMAL with the HDS.
NOTE: If the HDS screen shows UNDEFINED for sensor status, turn the ignition switch to LOCK (0), rotate the tire 1/4 turn, then turn the ignition
switch to ON (II), and try again. If the status does not change to normal, repeat this procedure until NORMAL is shown.
Is NORMAL indicated within one full turn of the tire?
YES -
The system is OK at this time. Clear the DTC with the HDS.?
NO -
Go to step 11.
11. Turn the ignition switch to LOCK (0).
12. Substitute a wheel with a known-good tire pressure sensor on the vehicle.
13. To memorize the sensor ID, drive the vehicle above 15 mph (24 km/h) for 40 continuous seconds, or memorize the ID with the HDS See:
Instrument Panel, Gauges and Warning Indicators/Tire Monitoring System/Tire Pressure Sensor/Testing and Inspection.
14. Turn the ignition switch to LOCK (0).
15. Turn the ignition switch to ON (II).
16. Check TPMS DATA LIST for RF, LF, RR, and LR TIRE PRESSURE SENSOR SIGNAL STATUS changing to NORMAL with the HDS.
NOTE: If the HDS screen shows UNDEFINED for sensor status, turn the ignition switch to LOCK (0), rotate the tire 1/4 turn, then turn the ignition
switch to ON (II), and try again. If UNDEFINED is still displayed, repeat this procedure until NORMAL is shown.
Is NORMAL indicated within one full turn of the tire?
YES -
Replace the tire pressure sensor on the client's wheel See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring System/Tire Pressure
Sensor/Service and Repair.?
NO -
Go to step 17.
17. Turn the ignition switch to LOCK (0).
18. Replace the appropriate initiator with a known-good initiator See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring
