Without Scan Tool

CLEARING TROUBLE CODES
NOTE: Clearing codes without a scan tool requires that you disconnect the negative battery terminal for ten seconds or longer to erase the diagnostic memory. This will also erase the memory from the clock and radio.

Erase the diagnostic trouble code using the following procedure:

1. Turn the ignition switch to OFF.
2. Disconnect the negative battery cable from the battery terminal for 10 seconds or more and then reconnect it.
3. Turn the ignition switch to ON and take a reading of the diagnostic output to check that a normal code is output.
