Self-Diagnostic System: Notes
WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2000 Plymouth Neon, 2000 Plymouth Breeze, 2000 Dodge Stratus, 2000 Dodge Neon, and 2000 Dodge Intrepid. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.
If a problem is sensed in a monitored circuit, a Diagnostic Trouble Code (DTC) will be stored in PCM and Malfunction Indicator Light (MIL) will illuminate, provided specific criteria are met. PCM will then enter limp-in mode, substituting information from other sources to compensate for component failure. Vehicle is operational in limp-in mode, but driveability may not be optimal.
A specific DTC results from a particular system failure. DTC only indicates problem circuit. It does not identify specific component failure in the circuit.
If problem is repaired or ceases to exist, PCM automatically clears DTC after 50 ignition on-off cycles. DTCs can also be cleared using scan tool. See CLEARING DTCS .
