2. REPLACE TRANSMITTER
1. Check low tire pressure warning lamp again for flashing, replace malfunctioning transmitter.
2. Carry out ID registration of all transmitters.
Can ID registration of all transmitters be completed?
YES >> GO TO 3.
NO >> GO TO Inspection 1. Refer to WT-24, "
Inspection 1: Transmitter or Control Unit (BCM)" .
3. VEHICLE DRIVING
Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for 10
minutes. Then check all tire pressures with CONSULT-II “DATA MONITOR ITEM” within 5 minutes.
Does
“DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?
