BCM for setting the status suitable for required operation, input/output sig-
nals are received from the BCM and received date is displayed.
DATA MONITOR Displays BCM input/output data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to
them.
SELF-DIAG RESULTS Displays BC M self-diagnosis results.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be
read.
ECU PART NUMBER BCM part number can be read.
CONFIGURATION Performs BCM configuration read/write functions.

- BCM
- Mechanical key
• NATS trouble diagnoses, system initialization and additional registration of other NATS mechanical key IDs
must be carried out using CONSULT-III hardware and CO NSULT-III NATS software. When NATS initializa-
tion has been completed, the ID of the inserted mechanical key can be displayed.
Regarding the procedures of NATS initialization and mec hanical key ID registration, refer to CONSULT-III
operation manual NATS.
SECURITY INDICATOR • Forewarns that the vehicle is equipped with NATS.
• Security indicator will not blink while the ignition knob is in ON or START state. NOTE:
Because security indicator is highly efficient, the battery is barely affected.
Condition of Secu rity Indicator
• When operating the ignition switch with Intelligent Key, se curity indicator lamp will turn off at once if ignition
switch is pressed and blinks when ignition switch is released.
• When operating the ignition switch with mechanical key security indicator will turn off at once if mechanical key is inserted into key cylinder and blinks when mechanical key is removed.
(Once the mechanical key is inserted into key cylinder, BCM will only perform the key ID verification with
mechanical key)
System Composition INFOID:0000000004305137
The function of the NATS consists of the following:
• Mechanical key
• NATS antenna amp. located in the ignition key cylinder
• BCM
• ECM (Engine control module)
• Security indicator
• Intelligent Key unit (if equipped)
NOTE:
The communication between ECM, BCM and/or Intelligent K ey unit uses the CAN communication sys-
tem.
ECM Re-communicating Function INFOID:0000000004305138
Performing the following procedure can automatically perform re-communication of ECM and BCM or Intelli-
gent Key unit, but only when the ECM has been replaced with a new one which has never been energized on-
board.
(In this step, initialization procedur e by CONSULT-III is not necessary)
NOTE:
• When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-III
Operation Manual NATS.

• If ABS actuator and electric unit (control unit) connec
tion is loose, tighten the piping to the specified
torque and recheck for leaks.
• If there is damage to the connection flare nut or A BS actuator and electric unit (control unit) threads,
replace the damaged part and recheck for leaks.
• When there is fluid leaking or seeping from a fluid connection, use a clean cloth to wipe off the fluid and recheck for leaks. If fluid is still seeping out, repl ace the damaged part. If the fluid is leaking at the ABS
actuator and electric unit (control unit), replace the ABS actuator and electric unit (control unit) assem-
bly.
CAUTION:
The ABS actuator and electric unit (control un it) cannot be disassembled and must be replaced
as an assembly.
3. Check the brake pads for excessive wear.
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION Make sure the battery positive cable, negative cabl e and ground connection are not loose. In addition, make
sure the battery is sufficiently charged.
ABS WARNING LAMP INSPECTION 1. Make sure ABS warning lamp turns on for approximately 2 seconds when the ignition switch is turned ON. If it does not, check CAN communications. If ther e are no errors with the CAN communication system,
replace the combination meter. Refer to IP-12, " Removal and Installation " .
2. Make sure the lamp turns off approximately 2 seconds after the ignition switch is turned ON. If the lamp does not turn off, conduct self-diagnosis of ABS act uator and electric unit (control unit). If no malfunctions
are detected in self-diagnosis, replace combination meter. Refer to IP-12, " Removal and Installation " .
3. After conducting the self-diagnosis, be sure to erase the error memory. Refer to BRC-18, " CONSULT-III
Function (ABS) " .
