Ensure the CAN bus system is terminated
at BOTH ENDS on the M2007 connector J6
and on the ATO board connector J9) with a
resistor equipped 6-pin connector. In early
units, it is possible that the resistor could
short. Disconnect power to the unit, unwrap
the resistor leads, and ensure they are not
touching.
Unplug and reseat all wiring harnesses in
CAN system. Check resistance between
pins 2 and 3 on the CAN network connec-
tors
. If checking with resistor at the end,
reading should be 120 ohms.
The locator pin in J2 of the AIF board is
either loose or in the incorrect position. See
the charts on pages 45-46 of this manual
for proper pin position.
