4. Set the main switch to “OFF”, then to “ON”

again, and then check that no fault code num-
ber is displayed.

TIP

If another fault code number is displayed, repeat
steps (1) to (4) until no fault code number is dis-
played.

5. Erase the malfunction history in the diagnos-

tic mode (code No.62). Refer to “SELF-DIAG-
