Clearing Trouble Codes

After completion of service, clear memory of trouble codes, by removing fuse No. 4 in fuse box. See Figure . Make sure that only code 12 is displayed. Disconnect diagnostic terminals.

NOTE: Disconnecting the 13 pole connector from the ECU will also clear the memory. Removing fuse No. 4 will also stop clock and other electrical equipment. Reset clock.
