Dual Electronic Automatic Temperature Control (DATC) Module Diagnostic Trouble Codes - DTCs
WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
If using the scan tool or front panel diagnostics to check for DATC DTCs:
- Check continuous DTCs.
- Run DATC self-test. Refer to FRONT PANEL DATC MODULE SELF-TEST (ON-DEMAND DIAGNOSTIC TROUBLE CODES - DTCS) .
General Information:
- If the DTC is continuous only and does not appear in the self-test, this indicates an intermittent fault condition, such as a poor wiring connection or a loose terminal. If the DATC does not appear after running the self-test it may also indicate that the DTC may no longer exist.
- If the DTC is continuous and appears in the self-test, this indicates a hard fault. A hard fault suggests a permanent wiring failure, disconnected connector or component failure.
