Inspection 5: “TIRE PRESSURE” Information In Display Unit Does Not Exist.AES000O9
DIAGNOSTIC PROCEDURE
1. SELF-DIAGNOSTIC RESULT CHECK
1. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector.
NOTE:
If “AIR PRESSURE MONITOR” is not indicated, go to GI-40, "
CONSULT-II Data Link Connector (DLC)
Circuit" .
2. Select “AIR PRESSURE MONITOR” on “SELECT SYSTEM” screen.
3. Select “SELF-DIAG RESULTS” on “SELECT DIAG MODE” screen.
4. Check display contents in self-diagnostic results.
Is
“CAN COMM CIRCUIT” displayed in the self-diagnosis display items?
YES >> Malfunction in CAN communication system. GO TO LAN-4, "Precautions When Using CONSULT-
II" .
NO >> GO TO 2.
2. CHECK DISPLAY CONTROL UNIT
Perform display control unit self-diagnosis. Refer to AV- 1 3 1 , "Self-Diagnosis Mode (DCU)" .
OK or NG
OK >> Replace low tire pressure warning control unit.
NG >> Repair or replace malfunctioning parts.
Inspection 6: ID Registration Cannot Be Completed.AES000OA
DIAGNOSTIC PROCEDURE
1. ID REGISTRATION (ALL)
Carry out ID registration of all transmitters.
Can ID registration of all transmitters be completed?
YES or NO
YES >> INSPECTION END.
NO >> GO TO WT-22, "

REMOVAL
1. Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.
2. Gently bounce tire so that transmitter falls to bottom of tire.
Place on tire changing machine and break both tire beads
ensuring that the transmitter remains at the bottom of the tire.
3. Turn tire so that valve hole is at bottom and bounce so that
transmitter is near valve hole. Carefully lift tire onto turntable and
position valve hole (and transmitter) 270 degree from mounting/
dismounting head.
4. Lubricate tire well and remove first side of the tire. Reach inside
the tire and remove the transmitter. Remove second side of tire.
