Clearing Diagnostic Memory

CLEARING DIAGNOSTIC MEMORY







To clear the diagnostic memory, short circuit the memory reset switch at the behind the electrical unit board.

Procedure for Clearing
1. Release the diagnostic switch.
2. Turn the ignition key switch ON.
3. Check that the Overheat warning light is displaying the Diagnosis Display Code.
4. Connect the harness or memory clear connector (24004 00Z09) to the memory reset switch terminal, and short circuit the switch.

NOTE: When connecting the harness, the battery voltage is applied to the Y/R cord side, so be careful not to short circuit any other part.

5. Check that the Overheat warning light and buzzer display shows the normal Diagnosis Display Code (0-1). The memory will be erased in about ten seconds.
6. Remove the special connector or harness from the memory reset switch terminal.
7. Connect the diagnostic switch.
