With Scan Tool

The diagnostic trouble codes in the EBCM memory are erased in one of three ways: diagnostic request line procedure, TECH 1 "CLEAR CODES" selection or ignition cycle default.

Whichever method is used, ensure to verify proper system operation and absence of diagnostic trouble codes when clearing procedure is completed.

The EBCM will not allow diagnostic trouble codes to be cleared until all diagnostic trouble codes have been displayed. Diagnostic trouble codes cannot be cleared by unplugging the EBCM, disconnecting the battery cables, or turning off the ignition.
