ISTA Test Plan Priority Error
MODEL
All
When diagnosing a vehicle using ISTA (Integrated Service Technical Application), fault code test plans are intended to be listed by "Priority". However, the priority given to test plans by ISTA may not be reliable. This may lead to unnecessary diagnosis being performed.
When ISTA was introduced, the entire diagnostics from DIS was migrated over to ISTA. Until all of the diagnostic data has been revised within ISTA, this type of error may occur.
Before starting diagnosis, the entire test schedule should be considered. Always use fault symptom diagnosis when available~ and use the customer complaint as the basis for determining which test plan to start first.
Note:
With each ISTA release, the priority given in the test schedule will become more reliable.
