- Check the console cable
connections.
- Verify the console cable is not
pinched or damaged. Perform a
voltage check on the console
cable.
Press the up or down arrow to adjust
resistance. Meanwhile, observe the
black wheel on the ECB motor: does
it turn at all (with or without the
tension wire attached)?
- If the wheel turns without the
wire, but not with the wire, the
ECB motor is damaged.
- If the wheel doesn't turn at all,
confirm Demo Mode is off. If the
issue remains, the ECB motor
may be burned out.
- Perform a voltage check on the
ECB motor.
- Check the tension wire. If it is
routed incorrectly, try to fix the
routing issue.
- Press the up or down arrow to
adjust resistance. Meanwhile,
observe the black wheel on the
ECB motor: does the wheel
start to rotate and then bounce
back to its original position
("skip")?
Troubleshoot the MCB; reference the
unit's service manual for more
information.
- Verify if the wrong quick key
connection cable was used
(A30/E30).
- Perform a resistance check.
--
- Reseat any loose
connectors.
- Replace the
console cable.
Replace the ECB
motor.
If the tension wire
routing issue
reoccurs after it is
fixed, or if you
observe the wheel
skipping, replace the
ECB motor.
Reference the unit's
service manual for
more information.
Replace the quick
key connection
cable.
Troubleshoot the
console.
