| SAFETY NOTICE | SN682 |
DATE: 3/30/20
REVISED:
TO: Owners, Users, Dealers, and Installers
MODELS AFFECTED: Digger Derricks
SUBJECT: International
Diamond Logic Programming
Issue:
Terex has become aware of some International
vehicles, using the Diamond Logic computer system, may disable auxiliary engine control. If the hood switch indicates open or a hood switch failure occurs, the logic in the Diamond Logic computer may disable the auxiliary engine control for engine stop/start. If the Diamond Logic computer system does not detect the hood switch signal, an emergency remote engine stop may not be possible.
Action:
What the Owner Must Do:
- Verify you are the owner of the unit serial numbers listed on the owner letter addressed to you.
- Complete the owner information form enclosed with the owner letter and return the form to [email protected] or fax to 1-605-882-5579. It will be important to include the unit serial number, vehicle VIN, unit location and contact information for arranging repair.
- If you are no longer the owner of an affected unit, send the unit serial number and buyer contact information to [email protected] or fax to 1-605-882-5579.
- Terex recommends the completion of this bulletin to take place within 60 days. If you have not been contacted to arrange a time for repair within 60 days of receipt of this bulletin and owner letter, contact Terex Utilities Warranty at 1-844-837-3948 or email [email protected].
Continued Use:
All machine users and operators must be notified of the following requirements for continued use of affected machines:
- Ensure the hood is closed at all times the digger derrick
is in use. - Be aware that if the hood switch fails or indicates the hood is open, the auxiliary engine control for engine stop/start may not work.
What Terex will Do:
Terex Utilities will facilitate arrangements with International
to make the appropriate repairs. The Diamond Logic computer program will be updated to only allow the vehicle hood switch to prevent a remote engine start.
Dealers and Installers: A letter is being sent to owners of affected units. If an owner contacts you about this bulletin; contact TEREX Utilities Warranty, at 1-844-837-3948, for further instructions.
