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.

WITH TRANSMITTER ACTIVATION TOOL
1. With the transmitter activation tool (J-45295) pushed against the
front-left transmitter, press the button then keep 5 seconds.
When ignition switch ON, then warning lamp is blinks as fol-
low diagram transmitter must be waken up.
2. Register the IDs in order from FR LH, FR RH, RR RH or RR LH. When wake up of each wheel has been
completed, a hazard warning lamp 2 time flashing.
3. After completing wake up of all transmitters, make sure tire pressure warning lamp go out.

Self-DiagnosisAES000NX
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit of this system
has pressure judgement and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground the self-
diagnostic (check) terminal. The malfunction location is indicated by the warning lamp flashing and the buzzer
sounds.
CONSULT-II
CONSULT-II Main Function
In a diagnosis function (main function), there are “WORK SUPPORT”, “SELF-DIAGNOSTIC RESULTS”,
“DATA MONITOR”, “CAN DIAG SUPPORT MNTR”.

How to Perform Trouble Diagnosis for Quick and Accurate RepairAES000NY
INTRODUCTION
Before troubleshooting, verify customer complaints.
If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
functioning. Hold and shake these parts to make sure they are securely connected.
When using a circuit tester to measure voltage or resistance of each circuit, be careful not to expand con-
nector terminals.
