How to Erase DTC ( With GST)
NGEC0552S0602
NOTE:
If the DTC is not for A/T related items (see EC-597), skip step 2.
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
2. Perform “SELF-DIAGNOSTIC PROCEDURE (Without CONSULT-II)” in AT section titled “TROUBLE
DIAGNOSIS”, “Self-diagnosis”. (The engine warm-up step can be skipped when performing the diagnosis
only to erase the DTC.)
3. Select Mode 4 with GST (Generic Scan Tool).
The emission related diagnostic information in the ECM can be erased by selecting Mode 4 with GST.
쐌 If the battery is disconnected, the emission-related diagnostic information will be lost after approx.
24 hours.

quicker than switching the mode selector on the ECM.
