Without Diagnostic Scan Tool

PROCEDURE
To clear BCM trouble codes, enter diagnostics. After the segment check and the codes are displayed, push the "LO" button to select the BCM system level, when "BCM?" is displayed, press the "HI" button, then press the "LO" button to select the "CLEAR CODES?" test type. When "CLEAR CODES?" is displayed then push the "HI" button. After 3 seconds the display will return to the next available test type for the selected system and the BCM codes will be cleared.

NOTES:
^ If PCM/ECM codes are cleared at any time, snapshot code information will be lost.
^ After a code has been cleared, a complete ignition cycle and test drive should be done. Then recheck for the code to ensure the code does not reset.
