Low Tire Pressure Indicator Does Not Come on, and No DTCs Are Stored

Low tire pressure indicator does not come on, and no DTCs are stored
1. Turn the ignition switch ON (II).
2. Check the low tire pressure indicator for several seconds when the ignition switch is turned ON (II).

Did the indicator come on and then go off?

YES - Go to step 3.

NO - Do the troubleshooting for the gauge control module. If necessary, substitute a known-good gauge control module, and recheck.

3. Lower the pressure in any tire until the low tire pressure indicator comes on tires.

NOTE: If 5 minutes has passed since the ignition switch has been turned on, turn the ignition switch off and wait 2 minutes, then turn back on again.

Does the indicator come on when the pressure drops below: Front 175 kPa (1.8 kgf/cm2, 25 psi), rear 168 kPa (1.7 kgf/cm2, 24 psi) or less?

YES - The system is OK at this time.

NO - Go to step 4.

4. Check the TIRE PRESSURE in the TPMS DATA LIST with the HDS, and compare with measured actual tire pressure.

NOTE: If the HDS screen shows UNDEFINED for sensor status, turn the ignition switch OFF, rotate the appropriate tire 1/4 turn, then turn the ignition switch ON (II), and try again. If UNDEFINED is still shown, repeat the procedure in the previous sentence until NORMAL is shown.

Is the indicated tire pressure on the HDS within 40 kPa (0.4 kgf/cm2, 6 psi) of the actual tire pressure?

YES - Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit, and recheck.

NO - Replace the tire pressure sensor.
