Read Failure Record Parameters
The service Read Failure Record Data ($12) is used to obtain failure record information that was
captured due to a fault detected within the node.
CAT provides two already predefined setup levels of the Read Failure Record Data service:
- The Read Failure Record Identifiers (sub-function parameter = $01),
- The Read Failure Record Parameters (sub-function parameter = $02).
Read Failure Record Parameters (sub-function parameter = $02) allows CAT to retrieve the data
parameters in the failure record associated with the failure record identifier. Failure record data
parameters consist of ECU inputs, outputs, and calculated values, which provide information about the
operating conditions of the vehicle at the time the DTC, is logged.
To read out the parameters of the failure record the Failure Record Identifier has to be configured. The
Setup button in the Main Diagnostic Setup window could activate the dialog box shown below.
The Failure Record Identifier consists of 4 bytes, which include the Failure Record Number and the
DTC Identifier (2 byte DTC number + 1 byte DTC fault type).
Note: Valid failure record identifier data values are obtained by CAT from the Read Failure Record
Identifiers ($01) level of this service.
Input the desired Identifier and acknowledge the setup by OK.
