rotate the tire 90 to 270锟斤拷. Then rapidly release the tire pressure and recheck the data.

A -- REPLACE TIRE PRESSURE WARNING ECU
From 08/2009
TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: C2165/65-C2169/69: Abnormal Temperature Inside ID1
Tire
DESCRIPTION
Each tire pressure warning valve and transmitter measures the internal temperature of its tire as well as tire pressure, and transmits the information to
the tire pressure warning ECU along with the transmitter ID. If the measured temperature is out of the specified range, the tire pressure warning ECU
recognizes it as a malfunction, outputs DTCs, and the tire pressure warning light blinks for 1 minute and then remains on.
HINT
It is necessary to perform the procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because
it cannot be identified by the output DTC.
INSPECTION PROCEDURE
NOTICE:
- When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using Techstream and note
them down before removal.
- It is necessary to perform initialization See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring
System/Testing and Inspection/Programming and Relearning/Initialization after registration See: Instrument Panel, Gauges
and Warning Indicators/Tire Monitoring System/Testing and Inspection/Programming and Relearning/Registration of the
transmitter IDs into the tire pressure warning ECU if the ECU and/or any of the valve and transmitters have been replaced.
PROCEDURE
1. CHECK TIRES
(a) Check that the tires are not flat, and have no indication of air pressure drop.
OK:
Tires are normal.
HINT
If a tire is damaged, the tire pressure warning valve and transmitter may also have been damaged at the same time.
NG -- REPLACE TIRE AND TIRE PRESSURE WARNING VALVE AND TRANSMITTER See: Instrument Panel, Gauges
and Warning Indicators/Tire Monitoring System/Tire Pressure Sensor/Service and Repair/Removal and Replacement/Removal
OK -- Continue to next step.
2. IDENTIFY TRANSMITTER CORRESPONDING TO DTC
(a) Set the tire pressure to the specified value See: Maintenance/Wheels and Tires/Testing and Inspection/Component Tests and General
Diagnostics.
(b) Turn the engine switch off.
(c) Connect Techstream to the DLC3.
