Self Test Adapter
Basic Use of G-scan Module NO: A-02-006
The self-test functions are used to check the Main DLC cable (P/No:
G1PDDCA001) and specific related circuits. Not all G-scan circuits are
checked with the self-test functions.
Basic operation of the self-test function is the loop-back theory.
Loop-back theory is verification between sent data from the G-scan
module and returned data, which passed through the pins of all the
outside connectors during the self-test.
Some communication circuits such as high speed CAN, low speed CAN
and SAE-J1708, cannot be checked with loop-back tests.
There are 2 self-test steps included in the Self Test function on the
Configuration menu.
z Step A: Performs test functions by automatically changing circuit
Configurations at the inner end of DLC connector of the G-scan
module.
