Corrective Action
Check that the red trailer switch
is in the neutral position when
no one is pushing or pulling the
switch.
If the switch is not in the neutral
position, determine if the switch
is stuck in another position
due to impeded movement
(e.g. pinched by a portion of
the dash). Remove any dash
or other components that may
be hindering the motion of the
switch. Verify the switch returns
to the neutral position.
If the switch does not return to
the neutral position automatically,
attempt to manually move the
switch to the neutral position.
If the DTC does not resolve once
the switch returns to the neutral
position, replace the DECU.
The DTC should resolve once
the switch returns to the neutral
position.
Verify there are no open wires or
shorts on the 2 CAN inputs,
Pins 13/15 on J1 and Pins 6/8 on
J2 connector.
Verify the 2 CAN inputs have
terminating resistors at the DECU
side and at the backbone.
Verify all ECUs on the CAN bus
communicate at the same baud
rate; OEM for assistance may be
necessary.
Verify the data from each CAN
input to the DECU has the same
data; OEM for assistance may be
necessary.
This DTC should resolve once
the cause is addressed.
