Data Link Connector (DLC)
WARNING: This page is about a different car, the 2000 Dodge Ram Wagon and 2000 Dodge Ram Van. However, it is still accessible from the selected car via links, so may be relevant.
Diagnostic Trouble Codes (DTC) are accessed through a 16-pin DLC using Chrysler's Diagnostic Readout Box (DRBIII®) scan tool or a generic scan tool. DLC provides an input signal to Powertrain Control Module (PCM) via the Serial Communications Interface (SCI) transmit circuit when using scan tool to retrieve DTCs from PCM via the SCI receive circuit. DLC input signal is also used by PCM when performing various tests on electronic control system. DLC communicates with other modules via the CCD bus circuit. See CCD BUS CIRCUIT .
Modules connected to the DLC via the CCD bus circuit are as follows.
- Air Bag Control Module (ACM)
- Anti-Lock Brake System (ABS) Controller Anti-Lock Brake (CAB) Module
- Central Timer Module (CTM)
- Mechanical Instrument Cluster (MIC) Module
- Powertrain Control Module (PCM)
