The CAT customer parameter worksheet is a three-page form from Caterpillar troubleshooting manual SENR5582-06 for the 3176B, C-10, C-12 and 3406E truck engines. It is not a procedure but a structured worksheet used to write down the customer programmable parameters for an engine before any service work begins.
What this document is — CAT customer parameter
The worksheet gives a technician a fixed place to record every customer programmable parameter before and after service work. Because the pages are a blank recording form, the value of the CAT customer parameter worksheet lies in capturing the truck’s settings so that nothing is lost when an ECM or personality module is changed. It is a simple document, but on an electronic 3406E truck engine it prevents an expensive mistake.
When to use the worksheet — CAT customer parameter
The manual pairs this form with the programming procedures, and it is filled in at several points in a job:
- Before replacing an ECM, so parameters can be reprogrammed identically
- Before flash programming or changing a personality module
- Whenever a rating or configuration change is planned
- As a service record handed back with the completed job
Why it matters
Customer programmable parameters control how a truck behaves — road-speed limits, PTO settings and similar values that the owner relies on and that may be protected by customer passwords. If they are lost during a repair, the truck may run differently than the owner expects, and a return visit becomes likely. Filling in the CAT customer parameter worksheet first means the exact configuration can be restored after the ECM or personality module work, so the truck leaves the shop behaving exactly as it did before the repair.
