MAN #650506C
Quick tips:
•
While the BIM is operating, the status light will flash green.
•
A steady green indicates it is powered up but not receiving any bus activity.
•
The display will flash green-yellow-green-yellow-red-red (rapid red flash with slow green flash) until it has been
calibrated in your vehicle. It cannot begin reading correctly until after this is completed.
•
A flashing yellow-red (steady red with a flashing green) indicates an open or shorted temperature sensor
connection.
Troubleshooting guide:
Problem
Possible cause
Solution
- No BIM data on instrument
readout
- BIM will not light up
- Power/data harness is not connected or
is damaged
- Module is damaged
- Inspect power/data harness and reseat
- Return for service. (See page [10])
- No BIM data on instrument
readout
- BIM has a steady-lit green
LED
- Interface cable is not connected
- On VHX systems, the BIM data is not
assigned to an LCD
- Interface cable is loose, or green data
wire is loose
- Connect the power/data cable to the BIM unit and the
instrument system control box
- Follow VHX instructions for Display / Locations to
enable the BIM display screen.
- Ensure both ends of the cable are properly seated
- BIM LED is flashing green-
red-red
- No BIM data on instrument
readout
- Another BIM is set with the same
channel ID
- Disconnect any other BIM and test alone
- Change ID of BIM following steps on page [4]
- Compass shows
interference (direction is
flashing or inverted color)
- Compass is not calibrated correctly
- Unit is picking up interference from
nearby steel in vehicle or roadway
- Follow Compass calibration instructions on pages 5-7
- Move BIM unit to location away from steel and higher
in vehicle
- Compass reads incorrectly
- Compass is not calibrated correctly
True North offset is incorrect
- Follow Compass calibration instructions on pages 5-7.
- Change the North offset (pages 5-7)
- Temperature does not read
correctly
- Loose connection on sensor wires
- Air temperature sensor is not getting
proper air flow
- Voltage or wiring problem in the vehicle
wiring harness
- Inspect and reconnect wires.
- Move the air temperature sensor to get clean air flow
and avoid engine heat
- Check wiring harness for loose or damaged wires
- Temperature reading
displays “---”
- SND terminal is shorted to ground
- Sender is damaged
- Check wire for damaged insulation. Repair/replace as
necessary.
- Replace sender
- Temperature reading
displays “EEE” / status LED
blinking yellow-red
- Sender is not connected to BIM-17-2
- Wire between BIM and sender is broken
- Sender is damaged
- Module is damaged
- Connect sensor to SND terminal.
- Test and replace wire.
- Replace sender.
- Return module for service. (see instructions)
- Temperature is always
“-40F” or “-40C”
- The temp sender is not connected
- Sender is damaged
- Check wire connections to the temperature sender
- Replace sender
