GM Service Manual Online
For 1990-2009 cars only

A DTC is cleared in only one of following three ways:

    • The IPC clearing DTC feature.
    • A scan tool
    • The ESC module will automatically clear the DTC if the malfunction has not occurred within 100 ignition cycles.

Disconnecting the battery or the ESC module connectors does not clear a DTC. Clear any history DTC after correcting a system fault in order to prevent future misdiagnosis.
