GM Service Manual Online
For 1990-2009 cars only

Notice: Turn the ignition OFF when installing or removing the ECM connectors and disconnecting or reconnecting the power to the ECM (battery cable, ECM pigtail, ECM fuse, jumper cables, etc.) in order to prevent internal ECM damage.

When the ECM sets a DTC, the malfunction indicator lamp (MIL) will be turned on only for a type A, B, and E but a DTC will be stored in the ECMs memory for all types of DTCs. If the the problem is intemittent, the MIL will go out after 10 seconds if the fault is no longer present. DTCs with type X do no exist for that version.

DTCs should be cleared after repairs have been completed. Some diagnostic tables will tell you to clear the codes before using the chart. This allows the engine control module (ECM) to set the DTC while going through the chart, which will help to find the cause of the problem more quickly.
