Clearing Codes Using CodeMate Tester
NOTE: When clearing codes without the use of a scan tool, the battery must be fully
charged. The ability to clear codes is directly dependent on the battery being fully charged
and able to start the engine with adequate cranking rpm.

A poorly charged battery or engine cranking problem may result in an ECM “reset” and may
not allow stored trouble codes to be cleared from EEPROM memory. If this condition exists,
BE SURE the battery is fully charged.
NOTE: If a low battery condition does exists the audio warning buzzer will come on for 2
seconds (as a result of an ECM reset) after engine start-up.

nostic Tool or the Rinda Scan Tool.
