If the Banks Brake does not pass
the FuNCtIONaL tEstING or
ceases to function properly, re-check
all connections per the installation
instructions. the following diagnostic
procedures could be carried out to
identify and correct the problem.
to check for proper Banks CBC
connections, measure the voltages
at the 14-pin connector on the CBC
wiring harness. these voltages should
be the same as the values shown in
table 3. refer to Figure 26 for the
wire locations. use Pin #6 on the
connector for ground.
NOtE: assure the ignition key is
in the on position but engine is not
running. to check the gray wire,
follow “sImuLatE COLD ENGINE
CONDItION” procedure below.
to sImuLatE COLD ENGINE
CONDItION, unplug the coolant
temperature sensor connector (with
the Gray Banks wire still attached)
from the sensor. the Gray wire
should read 5V; and with the throttle
released, the green light should be on.
If it is not, turn the ignition key to the
off position and unplug the Gray
Banks wire from the sensor. turn the
key to the on position without the
engine running. Wait five (5) second
and key off. Plug the Gray Banks
wire back into the coolant temperature
sensor cable. re-measure the voltage
and confirm it is at 5V.
If voltages are not present
or different, re-check the
connections. reconnect the
temperature sensor connector.
If all voltages are present, repeat
FuNCtIONaL tEstING. the
GrEEN LED will be lighted
indicating the Brake will function
as described.
If the GrEEN LED is lighted,
but the compressor does not
run, re-check connection of the
GrEEN and BLaCk wires in
