Never set the vehicle to READY.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair or replace harness or connectors.
3.
CHECK REMOTE KEYLESS ENTRY RECEIVER SIGNAL CIRCUIT
1. Turn the power switch OFF.
2. Check 10A fuse (No. 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 remote keyless entry receiver harness connector.
4. Check the continuity between BCM harness connector and remote keyless entry receiver harness con-
nector.
5. Check the continuity between BCM harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair or replace malfunctioning components.
4.
CHECK REMOTE KEYLESS ENTRY RECEIVER GROUND CIRCUIT
Check continuity between BCM and remote keyless entry receiver connectors.
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Repair or replace the malfunctioning harness or connector.
5.
CHECK TIRE PRESSURE SIGNAL
With CONSULT
1. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2. Stop the vehicle.
3. On “DATA MONITOR” select “AIR PRESS FL”, “AIR PRESS FR”, “AIR PRESS RR” and “AIR PRESS RL”.
4. Within 5 minutes after vehicle stopped, check that the tire pressures are within specification. Refer to
.

DTC CONFIRMATION PROCEDURE
1.
PERFORM DTC CONFIRMATION
With CONSULT
1. Turn the power switch ON.
CAUTION:
Never set the vehicle to READY.
2. Check the tire pressure for all wheels and adjust to the specified value. Refer to
.
CAUTION:
If the tire pressure before adjustment is close to the standard, reduce the tire pressure, and then
with the power switch ON, adjust the tire pressure again so that it is within the standard.
3. Perform “Self Diagnostic Result“” in “AIR PRESSURE MONITOR” of “BCM”.
Is DTC “C1716”, “C1717”, “C1718”, or “C1719” detected?
YES
>> GO TO 2.
NO
>> Inspection End.
2.
CHECK LOW TIRE PRESSURE WARNING LAMP
Check that after the power switch is turned ON, the low tire pressure warning lamp illuminates for approxi-
mately 1 second and then turns OFF.
Is the inspection result normal?
YES
>> Inspection End.
NO
>> Leave the power switch ON and proceed to
.
Diagnosis Procedure
INFOID:0000000010120194
1.
PERFORM TIRE PRESSURE SENSOR ID REGISTRATION
Perform tire pressure sensor ID registration for all wheels. Refer to
.
Is tire pressure sensor ID registration completed?
YES
>> GO TO 2.
NO
>> Replace applicable tire pressure sensor. Refer to
WT-47, "Removal and Installation"
2.
CHECK TIRE PRESSURE SIGNAL
With CONSULT
1. Check the air pressure for all wheels and adjust to the specified value. Refer to
.
2. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
3. Stop the vehicle.
4. Select in “Data Monitor“ ” in “AIR PRESSURE MONITOR” of “BCM” .
5. Within 15 minutes after vehicle stopped, read the values that are displayed for “AIR PRESS FL”, “AIR
PRESS FR”, “AIR PRESS RR”, and “AIR PRESS RL”.
DTC
Display Item
