The intelligent tester can display pending dtcs and current dtcs. Some dtcs are not stored unless a malfunction is detected in consecutive driving cycles. When a malfunction is detected in only one driving cycle, it is stored as a pending dtc.
Then connect the can vim to the dlc3.
Notice:
When simulating a symptom with the scan tool to check for dtcs, use normal mode.
For codes on the diagnostic trouble code chart subject to "2 trip detection logic", perform the following actions.
Turn the ignition switch off after the symptom is simulated once. Then repeat the simulation process again. When the symptom has been simulated twice, the mil illuminates and the dtcs are recorded in the ecm.
Then connect the can vim to the dlc3.
Hint:
When operating the tester to erase the codes, the dtcs and freeze frame data will be erased.
