Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Isolate The Problem: Notes
To isolate the problem is " to place apart from others".
The object here is to zoom in on the problem area. It is easy to be overwhelmed by a problem, just reaching for an ETM can add to the confusion. The DISplus provides automatic tests in test modules to aid in the determination of the exact area or cause of the problem.
The elimination of components from the diagnostic trail, shortens the path. The first question asked should be:
- Is the problem Hydraulic, Mechanical or Electrical?
Save time by NOT testing components that could not create the problem.
