Autodata - Diagnostic Trouble Codes Fault locations and probable causes - 2004 edition

Erasing Method 2
Ensure ignition switched OFF.
Method 1
Disconnect battery earth lead for 10 seconds.
Switch ignition ON.
WARNING: Disconnecting the battery may erase memory from
Connect LED test lamp between data link connector (DLC)
electronic units (e.g. radio, clock).
terminal 2 and battery positive 0.
Bridge data link connector (DLC) terminal 2 and earth with a
switched lead - contacts normally open 0.
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.
