Discussion:
Error Codes 1 & 24

Hello,

we have a LE20-66MP forklift with error codes "Err:001" and "Err:024".
At the moment it is not possible to drive the forklift.

Does anybody know what these error codes mean?
Does anybody have an error code list or a service manual for this model?

Thanks in advance!

Cheers
Josef

Hi tr_doctor,

thank you for your answer.

With "digital display" you mean the LISA diagnosis device?

Or is it possible via the forklifts(built-in) LCD Display?

Do you have a manual for that procedure?

Thanks in advance!

Cheers,
Josef

in digital display it is possible but when you not have experience it is difficult. Otherwise you need diagnostoc laptop with service software.

Hi tr_doctor,

thank you for your reply.

How can i set the parameters back to factory settings or reload them?
Is there any special equipment needed to do that?

Thank you!
