4.11 LOWER PRIORITY MODULES FOR
BREAKDOWN SERVICE
Modules A43 (IO-A) and A44 (IO-B) affect lower
priority functions. These modules can therefore
be used as spare parts for breakdown service
while on the road.
Functions lost if A43 is removed and used as
spare part:
o
High beams,
o
Ability to turn on the parking lights only,
o
“Watch your step” sign,
o
Driver's area lighting,
o
Tag axle activation,
o
Courtesy lights.
Functions lost if A44 is removed and used as
spare part:
o
Fresh air damper mix trap control,
o
Driver's area and entrance overhead light,
o
Front clearance lights.
4.12 MULTIPLEX MODULES
4.12.1 MCM
The MCM plays the role of interface between the
engine ECM, the transmission TCM, the telltale
panel module and other IO-A, IO-B modules.
When a multiplex module is being replaced, the
MCM will inform the new module of its role and
function accordingly to the vehicle options. It
keeps the specific back-up program of the
vehicle.
4.12.2 IO-A
IO-A modules receive inputs and control
outputs. IO-A's are used for all outputs of 1 amp
or less.
4.12.3 IO-B
IO-B modules receive inputs and control
outputs. IO-B's are used for outputs up to 30
amps.
4.13 MULTIPLEX MODULES REPLACEMENT
IO-A, IO-B multiplex modules can be replaced
and reprogrammed without having to connect a
computer to the vehicle. The MCM module must
however be reprogrammed using a laptop
computer equipped with VPG software.

4.13.1 Replacing IO-A Or IO-B Modules
o
Set the ignition switch to the ON position and
leave it in that position at all time while
performing this procedure.
o
On rear electrical junction panel, trip circuit
breaker CB6.
o
Replace the module (for IO-B modules,
disconnect the green connector first, then the
grey one and finish with the black connector.
To disconnect the black connector, slide
downwards the red latch. Remove the lower
screw that holds the cable attachment rod
onto the floor portion of the panel and flip the
rod up, this will relieve the IO-B module, (see
Fig. 21).
o
Reset circuit breaker CB6. This engages the
i/o autoprogramming.
o
The DID indicates "MUX
AUTOPROGRAMMING I/O MODULE
PLEASE WAIT" until the reprogramming is
complete unless a higher priority message
