The CAT service information report guide is a one-page section of Caterpillar manual SENR5582-06 that explains how to document a completed repair on the 3176B, C-10, C-12 and 3406E truck engines. After the correct repair has been verified, the manual says it is critical to record concise, detailed information that helps Caterpillar and the customer understand what was wrong and what was done.
What the report should contain — CAT service information
The CAT service information report is organised into three parts, each with specific guidance on the level of detail expected, so the record is genuinely useful to the next person who reads it.
Customer’s complaint manual information — CAT service information
Provide a copy of the PA-10 driver questionnaire and note whether the check-engine lamp was on continuously or intermittently, and whether symptoms such as low power were present at the time.
Failure cause manual information — CAT service information
State the number of diagnostic codes logged and whether a code was active. Identify the source of the problem and how it was found — for example, following procedure PC-31, a visual inspection showing wire abrasion on the engine harness, or dynamometer testing showing power below specification at 1700 rpm due to the loss of a cylinder injector.
How you repaired it
Describe the actual repair, such as repairing the wiring harness or changing the FLS/FTS per factory instructions, and be specific about parts and steps.
Why it matters
A well-written CAT service information report feeds accurate failure data back to Caterpillar, gives the customer a clear record of the work, and speeds any follow-up if the same symptom returns. It also protects the workshop by showing that the diagnosis followed the factory procedures rather than guesswork. Because the report ties the complaint, the failure cause and the repair together in one place, it becomes part of the engine’s service history and makes any warranty or goodwill review far quicker to settle.
