Vacuum/Boost setup.
If a Vacuum/Boost sensor is connected to one of the channels, there is an additional step to correct for
atmospheric pressure offsets due to elevation. After the BIM unit and sensor are connected and working, turn on the
ignition key without starting the engine and wait for 30 seconds. This will zero out the Vacuum/Boost sensor.
Troubleshooting quick tips:
While the BIM is operating normally, the status light will flash green.
A steady green indicates it is powered up but not receiving any bus activity.
A flashing yellow-red (steady red with a flashing green) indicates an open or shorted temperature sensor connection.
A green flash-red flash indicates the BIM is currently selected in the gauge setup menu.
A green-red-red flash indicates an ID conflict with another connected BIM.
Troubleshooting guide.
Problem
Sensor does not show on
gauge readout.
BIM will not light up at all.
Sensor does not show on
gauge readout.
BIM has a steady green
light.
Sensor does not show on
gauge readout.
BIM light is flashing
green-red-red
Gauge lights up, but does
not read correctly.
Gauge lights up, but displays SND terminal is shorted to ground.
"---".
Gauge lights up, but displays Sender is not connected to gauge.
"EEE".
Sensor voltage tests:
red wire: 4.5 – 5.0 V
white wire: 0.4 – 4.5V
black wire: 0 volts
With the SEN-09-6 vacuum/boost sensor the 0 psi gauge value will be approximately 1.0 – 1.2V depending on the
barometric pressure and altitude.
Possible cause
PWR wire does not have power.
GND wire does not have a good
ground.
Power/data harness is damaged.
Module is damaged.
Interface cable is not connected.
Interface cable is loose.
Another BIM is set with the same
channel ID.
On VHX systems, the BIM display
for this channel is disabled.
Another BIM is set with the same
channel ID.
Loose connection on sensor wires.
Connector not seated on sensor.
Channel sensor label setup is incorrect. Change label by entering BIM setup through gauge system.
Voltage or wiring problem in the
vehicle wiring harness.
Vacuum/Boost sensor is not zeroed.
Sender is damaged.
Wire between gauge and sender is
broken.
Sender is damaged.
Module is damaged.
(test with BIM powered and sensor connected.)
(0.4 – 0.6V with 0 psi)
Solution
Connect to a location that has power.
Connect to a different ground location.
Inspect harness. Repair or replace any damaged areas.
Return for service. (see instructions)
Connect the supplied 3.5mm data cable between the module and
the gauge control box.
Make sure both ends of the cable are seated in securely.
Test module works when connected to control box alone. Change ID
on one of the modules so each module uses a unique ID.
Follow instructions in VHX manual to enable the BIM display screen.
Test module works when connected to control box alone. Change ID
on one of the modules so each module uses a unique ID.
Inspect and reconnect wires.
Reattach the sensor plug, making sure the locking tab clicks in place.
Check wiring harness for loose or damaged wires.
Turn on the ignition key without starting the engine and wait for 30 seconds.
Check wire for damaged insulation. Replace if necessary.
Replace sender.
Connect SND terminal on gauge to sender terminal.
Test and replace wire.
Replace sender.
Return module for service. (see instructions)
