DTC CONFIRMATION PROCEDURE


1. TIRE PRESSURE SENSOR ID REGISTRATION

Perform tire pressure sensor ID registration. Work Procedure.
- GO TO 2.

2. PERFORM DTC CONFIRMATION

With CONSULT
1.Drive the vehicle at 40 km/h (25 MPH) or more for 10 minutes.

CAUTION:
Total time driving at a speed of 40 km/h (25 MPH) or more must be 10 minutes.
NOTE:
Avoid driving in area where radio wave cannot be transmitted/received.
2.Stop the vehicle.
3.Perform self-diagnosis for "AIR PRESSURE MONITOR" of "BCM".
Is DTC "C1708", "C1709", "C1710" or "C1711" detected?
YES- Proceed to .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK TIRE PRESSURE SIGNAL

With CONSULT
1.Select "DATA MONITOR" in "AIR PRESSURE MONITOR" of "BCM".
2.Check the values that are displayed for "AIR PRESS FL", "AIR PRESS FR", "AIR PRESS RR", and "AIR PRESS RL".
Are all tire pressures displayed 0 kPa (psi)?
YES (With intelligent key system)-GO TO 2.
YES (Without intelligent key system)-GO TO 4.
NO- Replace applicable tire pressure sensor. With Intelligent Key (With intelligent key system), Without Intelligent Key (Without intelligent key system).

2. CHECK RECEIVER CIRCUIT

1.Turn the ignition switch OFF.
2.Check 10A fuse (#7).

CAUTION:
Check that the fuse is not blown, that there are no other abnormalities, and that the fuse is of the specified capacity.
3.Disconnect BCM harness connector and tire pressure receiver harness connector.
4.Check the continuity between BCM harness connector and tire pressure receiver harness connector.





5.Check the continuity between BCM harness connector and ground.





Is the inspection result normal?
YES- GO TO 3.
NO- Repair or replace error-detected parts.

3. CHECK TIRE PRESSURE RECEIVER POWER SUPPLY CIRCUIT

1.Connect tire pressure receiver harness connector.
2.Check the voltage between tire pressure receiver harness connector and the ground when the ignition switch is turned ON and OFF.

CAUTION:
Never start the engine.





Is the inspection result normal?
YES- GO TO 6.
NO- Repair or replace error-detected parts.

4. CHECK RECEIVER CIRCUIT

1.Turn the ignition switch OFF.
2.Disconnect BCM harness connector and tire pressure receiver harness connector.
3.Check the continuity between BCM harness connector and tire pressure receiver harness connector.





4.Check the continuity between BCM harness connector and ground.





Is the inspection result normal?
YES- GO TO 5.
NO- Repair or replace error-detected parts.

5. CHECK TIRE PRESSURE RECEIVER POWER SUPPLY CIRCUIT

1.Connect tire pressure receiver harness connector.
2.Check the voltage between tire pressure receiver harness connector and the ground when the ignition switch is turned ON and OFF.

CAUTION:
Never start the engine.





Is the inspection result normal?
YES- GO TO 6.
NO- Replace the BCM.

6. CHECK TIRE PRESSURE SIGNAL

Check the function tire pressure receiver. Remote Keyless Entry Receiver (With intelligent key system), Without Intelligent Key System (Without intelligent key system).
Is the inspection result normal?
YES- Replace the BCM.
NO- Repair or replace error-detected parts.
