Fault Code Extraction

Fault Code Extraction can be carried out with a Compatible Scan Tool or manually.

Manual Extraction:

1. Switch ignition ON.
2. Confirm the Check Engine Lamp illuminates.
(The system will be in Diagnostic Test Mode I.)
3. Bridge Diagnostic Connector terminals 1 and 8.
Confirm the Check Engine Lamp extinguishes.
4. Wait at least two seconds.
5. Disconnect the bridge between Diagnostic Connector terminals 1 and 8.
(The system will be in Diagnostic Test Mode II.)
6. Read Fault Codes as flashes of the Check Engine Lamp.

Do not switch ignition off during this procedure or the system returns to Diagnostic Test Mode I.

Fault Code Erasure

Fault Code Erasure can be carried out with a Compatible Scan Tool or manually.

Manual Erasure:

1. Carry out Fault Code Extraction.
2. While the Fault Codes are being displayed, bridge Diagnostic Connector terminals 1 and 8.
3. Wait at least two seconds.
4. Disconnect the bridge between Diagnostic Connector terminals 1 and 8.
(This will erase the Fault Codes from ECM memory)

Should the above procedure fail to erase the Fault Codes;

Disconnect the battery negative cable or remove power to the ECM for 24 hours.

Ensure that other memory codes are known prior to performing this procedure.
