Fault Codes cont. - Section 5-BThe Display Freeze Frame Data checkbox adds Freeze Frame data for Fault Codes on control modules using the KWP-2000 / CAN / UDS protocols. Note: Not all control modules fully support this. As a rule of thumb, cars which were re-designed after 2003 will likely have some control modules that support it, and older designs will not. There's no harm in leaving this enabled in any case. However, un-checking it can make the results less cluttered in a scan which contains many fault codes. In vehicles that do not support Freeze Frame, that checkbox will not be present. One component of Freeze Frame data is the Fault Priority number as described below: Number 0 1 2 3 Meaning Undefined by the manufacturer. The fault has a strong influence on drivability, immediate stop is required. The fault requires an immediate service appointment. The fault doesn't require an immediate service appointment, but it should be corrected with the next service appointment. The fault recommends an action to be taken, otherwise drivability might be affected. The fault has no influence on drivability. The fault has a long term influence on drivability. The fault has an influence on the comfort functions, but doesn't influence the car’s drivability. General Note45 6 78Fault Frequency shows how many times the conditions that caused the fault have recurred, during all driving cycles. So, if you have a fault with a Frequency of 11, then conditions sufficient to trigger the fault have happened 11 times since the fault was stored. The counter can have values from 0 to 254. It is incremented with each occurrence of the fault (during all driving cycles). The Reset counter is a number that has been pre-assigned to each fault, with the number of problem-free driving cycles before the fault presumably clears itself. Each time a driving cycle occurs, and the conditions sufficient to trigger the fault do NOT occur, then the reset counter should go down by one. So if you have a fault with a Reset Counter of 40, if the controller goes through a problem-free driving cycle then that number should go down to 39.
