DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION 

With CONSULT-III

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-69, "Tire Air Pres-

sure"

. 

3.

Perform self-diagnosis for “AIR PRESSURE MONITOR”.

Is DTC “C1716”, “C1717”, “C1718”, or “C1719” detected?

YES

>> Proceed to 

WT-37, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000006225513

1.

CHECK TIRE PRESSURE

Check the air pressure of all wheels. Refer to 

WT-69, "Tire Air Pressure"

. 

Is the inspection result normal?

YES

>> Replace the DTC-detected malfunctioning transmitter. Refer to 

WT-66, "Removal and Installa-

tion"

.

NO

>> After adjusting the air pressure, GO TO 2.

2.

C1716, C1717, C1718, C1719 TRANSMITTER (PRESSURE DATA)

1.

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

WT-69, "Tire Air Pres-

sure"

.

2.

Perform transmitter ID registration for all wheels. Refer to
