2) WAITING DATA
CAN Bus Code = 237
- Cause: This warning occurs only if CAN BUS is PRESENT. At key-on the
eps-ac0 asks to the traction controller to send a list of parameters
via CAN Bus. From the request until the parameters are correctly
relieved, this warning occurs. The steer is not activated yet, and
the safety relays remain open when this warning is present.
3) WAITING FOR TRAC
CAN Bus Code = 239
- Cause: This warning occurs only if CAN BUS is PRESENT. At key-on the
eps-ac0 needs an assent from the traction controller to close the
safety contacts and to turn onto operational mode. Until this assent
is not relieved, this warning occurs. The steer is not activated yet
and the safety relays remain open when this warning is present.
4) EPS NOT ALIGNED
CAN Bus Code = 238
- Cause: This is a real alarm that cut off the traction. It occurs when the
system tries to perform an automatic centering at key on but no
straight ahead edge is detected within 6 secs.
- Remedy: Check the straight ahead switch (SW1 to CNA#3) is right working.
