Switches into the electrical center

The Volvo 9700 US/CAN bus is equipped
with additional "push button type" switches
into the electrical center.
This additional switches are:
Air conditioning test
Using this switch the driver can check if the
air condition is working.
MCM (Master Control Module) service switch
There is a switch in the electrical center
compartment (with a lock symbol) that needs
to be activated when the MCM is being
programmed. It is only intended to be used
when an update on MCM software is needed.
This switch was added because during
programming, MCM doesn't have control
over its output signals. In this case, the body
relay (K400) keeps opening and closing, not
allowing the MCM programming process. If
this switch is activated, the start is disable
and an indicator is displayed in the cluster (to
refer related with this symbol, see separate
operating instructions: "Driver information
display").
To refer about K400 power relay, see the
following section in this manual: "I-Start
system", page 131.
