Vehicles 2000 onwards are fitted with a 16-pin diagnostic behind the centre console on the passenger side. The codes can be read by bridging the two pins in the service connector and reading the MIL on the instrument cluster (all models). for 92-95 models it is gray, 96-00 models its blue. By default it is inserted into a green rubber housing. The service check connector (2-pin) is located under the dashboard, above the passenger side kick panel. In order to retrieve any stored DTC's, either a fault code reader must be connected to the vehicle's data link connector (located above the Service Check Connector), or read from the MIL in the instrument cluster. Should an engine management component fail, the incorrect (or implausible) signal is recognised by the PCM, which stores a Diagnostic Trouble Code (DTC), and where appropriate, illuminates the Malfunction Indicator Light (MIL)/Check Engine Light (CEL) in the instrument cluster. This facility is built into the PCM, and is designed to alert the driver to a system component fault which may result in a higher than normal emissions of harmful exhaust/fuel vapour gases and speed up the engine management troubleshooting procedure.
