DIAGNOSTIC TROUBLE CODE
A Diagnostic Trouble Code (DTC) indicates the PCM or TCM has recognized an abnormal condition in the system.

Remember that DTC's are the results of a system or circuit failure, but do not directly identify the failed component or components.

NOTE: For a list of DTC's, refer to the charts in this section.

Bulb Check
Key ON: Bulb illuminated until vehicle starts, as long as all once per trip (readiness) monitors completed. If monitors have not been completed, then: Key ON: bulb check for about 8 seconds, lamp then flashes if once per trip (readiness) monitors have not been completed until vehicle is started, then MIL is extinguished.

Obtaining DTC'S Using DRB Scan Tool
1. Connect the DRB scan tool to the data link (diagnostic) connector. This connector is located in the passenger compartment; at the lower edge of instrument panel; near the steering column.
2. Turn the ignition switch on and access the "Read Fault" screen.
3. Record all the DTC's and "freeze frame" information shown on the DRB scan tool.
4. To erase DTC's, use the "Erase Trouble Code" data screen on the DRB scan tool. Do not erase any DTC's until problems have been investigated and repairs have been performed.

Obtaining DTC'S Using Ignition Key
1. Cycle the ignition key ON - OFF - ON - OFF - ON within 5 seconds.
2. The Odometer will show the P-code for the DTC code number. Refer to the Emission section for the DTC chart for a detailed explanation of the DTC codes.
3. If no DTC's are present, the cluster will display one of two texts: "P1684" and "done" or only "done".
- P1684 is only a status and indicates that the PCM memory has been cleared within the last 50 ignition cycles and does not indicate a problem.
- done indicates that NO DTCs are present and the procedure is complete.
