Customer passwords must meet the following criteria:
- Alphanumeric
- Eight characters in length
The software for the Electronic Control Module (ECM) does not require the use of customer passwords. As an option, the customer can use one customer password to protect the parameters that have been programmed into the ECM, or to use two customer passwords for this protection.
If customer passwords have been entered, then the customer passwords are required to change any parameter that is customer programmable. Parameters that are customer programmable are those parameters that affect the engine speed limits, the power rating within an engine family and the PTO operation. Refer to Troubleshooting, "System Configuration Parameters" for more detail on parameters that are customer programmable.
Use the Caterpillar Electronic Technician (ET) to change parameters that are customer programmable. To obtain customer passwords, contact the owner of the engine. If the owner has lost the owner's passwords, customer passwords may be read by using Cat ET.
Note: Factory passwords are required in order to read customer passwords.
Use the following procedure in order to read customer passwords with Cat ET:
- Connect Cat ET to the service tool connector. Access the "Utilities menu". Then access "View Passwords" under the "Utilities menu".
- When the "Factory Password" screen appears, record the information that is listed on the "Factory Passwords Worksheet". Refer to Troubleshooting, "Factory Passwords Worksheet" for additional information.
- Obtain the factory passwords. The information that is recorded on the "Factory Passwords Worksheet" must be provided. When you obtain the factory passwords, a permanent record of your access is generated at Caterpillar.
- From the "Factory Password" screen, enter the factory passwords.
- When the "Read Customer Passwords" screen appears, record the customer passwords. The customer passwords may then be used to change parameters that are customer programmable.
