Control Unit Input/Output Signal StandardAES000NU
Standards using a circuit tester and oscilloscope.
( ): Wire color
ID Registration ProcedureAES000NV
ID REGISTRATION WITH TRANSMITTER ACTIVATION TOOL
This procedure must do after replace transmitter or low tire pressure warning control unit.
1. Turn ignition switch “OFF”.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector.
3. Touch “AIR PRESSURE MONITOR”, “WORK SUPPORT” and “ID REGIST”.
NOTE:
If “AIR PRESSURE MONITOR” is not indicated, go to GI-40, "
CONSULT-II Data Link Connector (DLC)
Circuit" .
4. With the transmitter activation tool (J-45295) pushed against the
front-left transmitter position of the tire air valve, press the button
then keep 5 seconds.
5. Register the IDs in order from FR LH, FR RH, RR RH or RR LH. When ID registration of each wheel has
been completed, a buzzer sounds and hazard warning lamp blinks.
6. After completing all ID registrations, press “END” to complete the procedure.
NOTE:
Be sure to register the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results dis-
play will not function properly.

connector terminal and ground while front wiper (HI, LO) is oper-
ating.
Without CONSULT-ll
1. Connect IPDM E/R connector and front wiper motor connector.
2. Start up auto active test, and check voltage between IPDM E/R
harness connector terminal and ground while front wiper (HI,
LO) is operating.
OK or NG
OK >> Replace front wiper motor.
NG >> Replace IPDM E/R.
6. CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM
With CONSULT-ll
Select “BCM” on CONSULT-II. With “WIPER” on “DATA MONITOR”,
confirm that “FRONT WIPER INT”, “FRONT WIPER LOW”, and
“FRONT WIPER HI” turn ON-OFF according to wiper switch opera-
tion.
Without CONSULT-ll
Refer to LT- 11 3 , "
Combination Switch Inspection" .
OK or NG
OK >> GO TO 7.
NG >> Check wiper Switch. Refer to LT- 11 3 , "
Combination
Switch Inspection" .
7. CHECK CIRCUIT BETWEEN IPDM E/R AND BCM
Select “BCM” on CONSULT-II, and perform self-diagnosis for
“BCM”.
Displayed self
-diagnosis results
NO DTC>>Replace BCM. Refer to BCS-15, "Removal and Installa-
tion of BCM" .
