INSPECTION PROCEDURE

NOTICE:

When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.

It is necessary to perform initialization () after registration () of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.

1.CHECK HARNESS AND CONNECTOR (TIRE PRESSURE WARNING ECU AND RECEIVER - TIRE PRESSURE WARNING ANTENNA)

Disconnect the tire pressure warning ECU and receiver L60 connector.

Disconnect the tire pressure warning antenna (for Rear Side) L59 connector.

Disconnect the tire pressure warning antenna (for Front Side) A64 connector.

Measure the resistance according to the value(s) in the table below.

HINT:

Because the coaxial cable that is used for the tire pressure warning antenna consists of a center conductor and an outer shielding layer (-), this measurement should be performed to ensure that there is no malfunction in the coaxial cable.

Standard Resistance:

Tester Connection	Condition	Specified Condition
L60-9 (EC3) - L59-1 (RR1)	Always	Below 1 Ω
L60-8 (EC2) - A64-1 (FR1)	Always	Below 1 Ω
L60-9 (shielded wire) - L59-1 (shielded wire)	Always	Below 1 Ω
L60-8 (shielded wire) - A64-1 (shielded wire)	Always	Below 1 Ω
L60-9 (EC3) - L59-1 (shielded wire)	Always	10 kΩ or higher
L60-8 (EC2) - A64-1 (shielded wire)	Always	10 kΩ or higher
L60-9 (shielded wire) - L59-1 (RR1)	Always	10 kΩ or higher
L60-8 (shielded wire) - A64-1 (FR1)	Always	10 kΩ or higher

REPAIR OR REPLACE HARNESS OR CONNECTOR

OK
