Reading Codes


Reading the control module memory is one of the first steps in OBD II system diagnostics. This step should be initially performed to determine the general nature of the fault. Subsequent readings will determine if the fault has been cleared.

Reading codes can be performed by any of the methods below:

Read the control module memory with the Generic Scan Tool (GST)
Read the control module memory with the Vag 1550 tester

To read the fault codes, connect the scan tool or tester according to the manufacturer's instructions. Follow the manufacturer's specified procedure for reading the codes.
