Troubleshooting, Its Overview And Procedures: Notes

WARNING: This page is about a different car, the 2002 Isuzu Axiom. However, it is still accessible from the selected car via links, so may be relevant.

The automatic air conditioner is equipped with the "Self-Diagnosis Function" to check its major components.

This function makes access to the sensors, actuators and blower fan motor system easier when checking them up and, when a failed part is located, this function restores its original performance.

When implementing the troubleshooting, this self-diagnosis function narrows the range to be searched at the first step, then check relevant parts one by one according to the "Checking Procedures by Failed Location". As for a location this function is unappreciable, the system accurately determines characteristics of a given trouble and checks relevant parts according to the "Checking Procedures by Failed Location".

The following illustrates basic troubleshooting flow.
