>> GO TO 7 after malfunctioning transmitter replacement.

6.

CHECK TIRE PRESSURE MONITORING SYSTEM

With CONSULT-III

1.

Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.

2.

Check all tire pressure with CONSULT-III “DATA MONITOR” within 15 minutes after vehicle speed
becomes 17 km/h (11 MPH). 

Does “DATA MONITOR” displayed the standardized value without turning low tire pressure warning lamp ON? 

YES

>> INSPECTION END

NO

>> Replace BCM. Refer to 

BCS-79, "Removal and Installation"

.

7.

CHECK ID REGISTRATION

With CONSULT-III

1.
