1.CHECK TIRE PRESSURE SIGNAL With CONSULT-III

1. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2. Within 5 minutes, select “DATA MONITOR” for the CONSULT-III “AIR PRESSURE MONITOR”.
3. Read the values that are displayed for “AIR PRESS FL”, “AIR PRESS FR”, “AIR PRESS RR”, and “AIR PRESS RL”.

   Monitor item | condition | Displayed value
   AIR PRESS FL | Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes. | Internal pressure of tires
   AIR PRESS FR
   AIR PRESS RR
   AIR PRESS RL

Is a tire pressure of 0 kPa (Psi) displayed for all wheels?
YES>>GO TO 2.
NO>>GO TO 4.
2.CHECK RECEIVER CIRCUIT

1. Turn the ignition switch OFF.
2. Disconnect the low tire pressure warning control unit harness connector and tire pressure receiver harness connector.
3. Check the continuity between the harness connector terminals of the low tire pressure warning control unit and receiver.

Is the inspection result normal?
YES>>GO TO 3.
NO>>Repair or replace the malfunctioning parts.
3.CHECK TIRE PRESSURE RECEIVER POWER SUPPLY CIRCUIT

1. Connect the low tire pressure warning control unit harness connector.
2. Turn the ignition switch ON.
   ■ CAUTION ■
   Never start the engine.
3. Check the voltage between the tire pressure receiver harness connector and ground.

Tire pressure receiver | — | Voltage
Connector | Terminal
E16 (Front LH) | 1 | Ground | 7 - 16 V
E44 (Front RH)
B58 (Rear LH)
B246 (Rear RH)

Is the inspection result normal?
YES>>GO TO 4.
NO>>Replace the tire pressure receiver.
4.REGISTER THE TRANSMITTER ID
Perform transmitter ID registration. Refer to Transmitter ID Registration Procedure.
Is transmitter ID registration been completed?
YES>>GO TO 5.
NO>>Replace the transmitter.
5.CHECK LOW TIRE PRESSURE WARNING CONTROL UNIT
With CONSULT-III

1. Drive for several minutes at a speed of 40 km/h (25 MPH) or more, then stop the vehicle.
2. Within 15 minutes, use CONSULT-III “DATA MONITOR” to display the tire pressure for all wheels.
3. Check that the displayed tire pressure is the specified value.

   Monitor item | Condition | Displayed value
   AIR PRESS FL | Drive for several minutes at a speed of 40 km/h (25 MPH) or more, then stop the vehicle. | Internal pressure of tires
   AIR PRESS FR
   AIR PRESS RR
   AIR PRESS RL

Is the inspection result normal?
YES>>INSPECTION END
NO>>Replace the low tire pressure warning control unit.
