Autodata - Diagnostic Trouble Codes Fault locations and probable causes - 2004 edition
Erasing NOTE: Some models 1992 -+ may require diagnostic equipment to erase trouble codes. Switch ignition OFF. Disconnect battery earth lead for 60 seconds. WARNING: Disconnecting battery may erase memory from electronic units (e.g. radio, clock). Repeat checking procedure to ensure no data remains in ECM fault memory.
