Steering Error Flash Codes
Failure and errors detected by the self-diagnostics in the
steering ECU are presented to the operator as a series
of flashes of the Power LED.
There are 2 to 12 flashes, interrupted by a short pause.
Multiple errors are flashed in rotation, with a long pause
between each error code. A maximum of five error states
are reported in any single rotation.
Any of these errors causes the ECU to default the
hydraulic steering to “float”.
Certain Machine Damage:
Do not back up if ANY of these errors occurs.
Steering is disabled.
The wheels cannot fully caster and machine damage will
result. If the problem cannot be corrected in the field, drive
forward to remove the planter from the field.
