WARNING: Disconnecting the battery may erase memory from Connect LED test lamp between data link connector (DLC) electronic units (e.g. radio, clock). terminal C3 and battery positive O. Bridge data link connector (DLC) terminal C2 and earth with a switched lead - contacts normally open O. Operate switch for 2,5-5 seconds. LED or MIL will now flash trouble code 12. Repeat switch operation until code 11 is displayed. Operate switch for 10-20 seconds. Switch ignition OFF.
