SIMPLE WORKFLOW

Three rules keep diagnosis clean

1
Identify

Decode the VIN, read every module, and save the exact code and freeze frame before clearing anything.

2
Test

Follow the ordered checks. Inspect first, measure second, and replace a part only after the fault is proven.

3
Verify

Repeat the original conditions, confirm the symptom is gone, and make sure the code or warning does not return.
