STATUS CODE
DESCRIPTION OF STATUS
CAUSE OF STATUS INDICATION
-69
The power steering coil current is too
high during the run mode.
This status code will be displayed when the current in the
power steering driver circuit exceeds current limit during the
run mode. The control is reset by recycling the key switch.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
•
=
Shorted power steering control coil
•
=
Short between wires connecting to the
power steering coil (wire # 10 and 60)
