System Tests: Notes
CAUTION:
DO NOT replace PASSLOCK(R) module unless there are no VCM DTCs and a current PASSLOCK(R) module DTC exists after system check and DTC test has been completed. DO NOT replace PASSLOCK(R) module based on history codes.
NOTE:
System tests are written specifically for General Motors' Tech 2 scan tool. A generic scan tool may not be capable of performing all necessary test functions.
