The body controller area network (B-CAN) and the fast controller area network (F-CAN) share information between
multiple electronic control units (ECUs). B-CAN communication moves at a slower speed (33.33 kbps) for convenience
related items and for other functions. F-CAN information moves at a faster speed (500 kbps) for ‘‘real time’’ functions
such as fuel and emissions data. To allow both systems to share information, the gauge control module translates
information from B-CAN to F-CAN and from F-CAN to B-CAN.
 The single wire method is used between the units not requiring the communication to move at a fast speed.
 Using a single wire method reduces the number of the wires used on the body controller area network.

3: TYPE S and ’08 Premium and ’09 models
At the initial stage of the self-diagnostic function, the beep sounds intermittently, the beeper sounds continuously
when any of the following switch inputs are switched from OFF to ON:
Cruise control main, dash lights brightness controller volume ( ), ( ) button, mph km/h switch, parking brake switch,
SEL/RESET switch, SET, RESUME, CANCEL switches, and VSA OFF switch . : ’07 TYPE S and ’08-09 models
When entering the self-diagnostic mode, the beeper sounds five times.
When entering the self-diagnostic mode, all the segments blink five times.
When entering the self-diagnostic mode, the tachometer needle sweeps from the minimum position to maximum
position, then returns to the minimum position.
NOTE:
After the beeper stops sounding and the gauge needle returns to the minimum position, pushing the SEL/RESET
switch starts the Beeper Drive Circuit Check (one beep) and the Gauge Drive Circuit Check again.
The check cannot be started again until the gauge needle returns to the minimum position.
If the needle fails to sweep, or the beeper does not sound, replace the gauge control module (tach).

System Description
Mechanical key
(Including transponder) Immobilizer key
MICU
(Imoes circuit) Mechanical key
Steering lock assembly Immobilizer-keyless
control unit
ECM/PCMTransmitter
(Including
transponder)
The vehicle is equipped with a type VI immobilizer system that will disable the vehicle unless a programmed ignition
key is used.
This system consists of a transponder combined with a keyless transmitter, immob
ilizer-keyless control unit, the MICU
(has built-in imoes unit), immobilizer indicator, and the ECM/PCM.
When the immobilizer key (programmed by the HDS) is inserted into the ignition switch and turned to ON (II), the
immobilizer-keyless control unit sends power to the trans ponder in the ignition key. The transponder then sends a
coded signal back to the immobilizer-keyless control unit which then sends a coded signal to the ECM/PCM and the
MICU (imoes unit). The ECM/PCM and MICU (imoes unit) identify this code signal, then fuel power is supplied.
NOTE: The transmitter is automatically programmed to the vehicle when a transponder is programmed by the HDS.
If the wrong key has been used or the code was not received or recognized by the unit, the indicator will come on for
about 2 seconds, then it will blink until the ignition switch is turned to LOCK (0). When the ignition switch is turned to
LOCK (0), the indicator will blink ten times to signal that the unit has reset correctly, then the indicator will go off.
