DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION

With CONSULT

1.

Turn the ignition switch ON.

CAUTION:

Never start the engine.

2.

Check the tire pressure for all wheels and adjust to the specified value. Refer to

WT-51, "Tire Air Pres-

sure"

.

CAUTION:

If the tire pressure before adjustment is close to the standard, reduce the tire pressure, and then
with the ignition switch ON, adjust the tire pressure again so that it is within the standard.

3.

Perform self-diagnosis 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 ignition 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

>> After erase DTC, INSPECTION END.

NO

>> Leave the ignition switch ON and proceed to

WT-29, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009653436

1.

PERFORM TIRE PRESSURE SENSOR ID REGISTRATION

Perform tire pressure sensor ID registration for all wheels. Refer to

WT-23, "Work Procedure"

.

Is tire pressure sensor ID registration completed?

YES

>> GO TO 2.

NO

>> Replace tire pressure sensor. Refer to

WT-48, "Removal and Installation"

.

2.

CHECK TIRE PRESSURE SIGNAL

With CONSULT

1.

Check the tire pressure for all wheels and adjust to the specified value. Refer to

WT-51, "Tire Air Pres-

sure"

.

2.

Stop the vehicle.

3.

Select “DATA MONITOR” in “AIR PRESSURE MONITOR” of “BCM”.

4.

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”.

Which tire pressures is displayed as 438.60 kPa (4.47 kg/cm

2

, 63.60 psi)?

DTC

Display Item
