Customer Passwords
Customer Password #1
Customer Password #2
Description:
To protect the engine against unauthorized
reprogramming once the parameters are set, the
customer can specify either one or two passwords
to control access to the parameters stored in the
electronic control module (ECM). However, the use of
passwords is not required for Cat electronic engines to
operate. Both passwords can be up to 10 alphanumeric
characters in length.
Once these passwords are programmed, they are
required to gain access to the customer specifi ed
parameters. No one can change the pre-programmed
Cruise Control parameter for instance, even if they
were to have access to a service tool, without also
knowing the correct password(s). If both passwords
are programmed, then both will be needed in order to
change a customer specifi ed parameter.
If the password is misplaced or forgotten the customer
will have to contact either his Caterpillar dealer or
authorized truck dealer to view the passwords. This
requires a higher level of security called a factory
password.
Available:
All Electronically Controlled Engines
Range:
Range Cat Default

Advantages:
Programming in a password or words help make the
customer’s electronics specifi cations more secure and
resistant to tampering.
Disadvantages:
If the password(s) is(are) forgotten, arrangements must
be made with an authorized dealer to obtain a factory
password.
Recommendations:
✔ Caterpillar recommends that electronic engines be
protected by passwords and that those passwords
be kept secure.
