HOW TO PROCEED WITH
TROUBLESHOOTING
HINT:
• Use the following procedures to troubleshoot the tire
pressure warning system.
• *: Use the intelligent tester.
NEXT
(a) Interview the customer to confirm the trouble.
HINT:
It is important to collect as much specific information as
possible from the customer to allow for a quick repair.
NEXT
(a) Adjust all tire pressures to the standard values.

INITIALIZATION
1. DESCRIPTION OF INITIALIZATION
(a) Perform initialization in the following cases:
• Before delivery of a new vehicle.
• After replacement of the tire pressure warning
ECU*.
• After replacement of the tire pressure warning
valve and transmitter.
• Specified tire pressure changes depending on
the size or type of the tire.
*: Perform initialization after the transmitter ID
registration is completed (See page TW-20).
(b) Before initialization
(1) Set the air pressure of all tires to the specified
value.
Cold tire inflation pressure
NOTICE:
Perform the tire pressure adjustment after
the vehicle has sufficiently cooled down. If
the vehicle is not sufficiently cooled down,
increase the air pressure by 20 to 30 kPa (0.2
to 0.3 kgf/cm
2, 2.9 to 4.3 psi) above the
specified value.

2. INITIALIZATION PROCEDURE
(a) Make sure that the ignition switch is off.
(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Select "TIREPRESS" by following the prompts
displayed on the intelligent tester.
(e) Press the tire pressure warning reset switch within
30 seconds after turning the ignition switch ON.
Keep the tire pressure warning reset switch pressed
for 3 seconds or more with the ignition switch ON.
(f) Check that the tire pressure warning light blinks 3
times (1 second ON, 1 second OFF).
HINT:
Initialization will be completed if signals are received
from all the wheels.
(g) Wait for 5 to 6 minutes with the ignition switch ON.
NOTICE:
• The initialization is normally completed
within 5 to 6 minutes.
• If the initialization has not been completed
successfully, DTC C2177/77 is set after the
vehicle is driven for 20 minutes or more.
• The initialization can be terminated by
connecting terminals TC and CG of the DLC3
connector.
3. CHECK THAT INITIALIZATION HAS BEEN
COMPLETED
(a) Confirm that the data of tire pressure of all tires are
displayed on the intelligent tester screen.
