Table 1: Troubleshooting Tips
No.
Potential Cause
What to Check
5. The EXM monitor is
not communicating to
the Stow Module,
7095, over the J1939
CAN bus.
Verify that the 7095’s internal red “Error” LED is NOT lit when the
STOWLAMP / STOWSIGNAL is not working.
o
Open the Stow Module, 7095, according to the “Configuration
Issues” section in this troubleshooting guide.
o
While the cover’s removed, carefully plug in the 12-pin Deutsch
connector.
o
Apply power to the system.
o
Verify that the red “Error” LED is NOT lit.
Refer to Table 2: Stow Module Internal LED States and
Figure 1: Stow Module LED internal location in this
troubleshooting guide.
If the 7095’s internal red “Error” LED is lit, then the Stow Module (7095) is
not communicating with the EXM monitor.
o
Verify that the J1939 CAN bus is properly terminated.
There should be two, and only two, termination points at
each end of the J1939 CAN bus. EXM devices on the
J1939 bus can be configured to be terminated or not
terminated. Refer to the “Configuration Issues” section in
this troubleshooting guide.
o
Verify that the J1939 CAN bus and branch (stub) lengths (and
other J1939 CAN bus physical properties) are in accordance with
SAE J1939-11.
o
Verify that the SW1 setting on the 7095 circuit board is set to the
number that corresponds to the EXM monitor’s Group number
according to the “Configuration Issues” section in this guide.
If the monitor’s group number is not known, turn the switch
to each of the four positions and see if the red “Error” LED
turns off after one minute of operation at each switch
setting.
If changing the switch setting does not work, record a
diagnostic file for the EXM system according to step “M.
Write Diagnostic File”* of the EXM monitor’s Installation,
Operating, and Maintenance Instruction manual. Contact
Elkhart Brass to make arrangements to have the diagnostic
file reviewed.
If the 7095’s internal red “Error” LED is NOT lit, then the Stow Module,
7095, is receiving at least some CAN messages from the EXM monitor.
o
Verify that after the EXM monitor stow operation completes, the
blue “Status” LED turns on.
o
Verify that when the EXM monitor is moved out of the stow
position, the blue “Status” LED turns off.
o
If the blue “Status” LED responds in accordance with the previous
two conditions, then the EXM monitor is correctly communicating to
the Stow Module, 7095. Investigate other Potential Causes.
6. The Stow Module,
7095, is damaged.
Inspect the outside of the Stow Module, 7095, for damage.
Open the Stow Module, 7095, according to the “Configuration Issues”
section in this troubleshooting guide.
Inspect the circuit board for damaged areas or components.
If any suspected damage is found, contact Elkhart Brass (800-346-0250)
