EIS Diagnostics

WARNING: This page is about a different car, the 2008 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.

Most problems with the Starting System can be identified with basic conventional diagnostic methods. However, electrical or CAN-C bus faults related to the EIS, PCM or ECM will require a scan tool to access the On-Board Diagnostics (OBD) functions of the PCM (or ECM, if equipped with a diesel engine). The EIS is monitored by the PCM or ECM (or ECM, if equipped with a diesel engine) via the CAN-C bus, and may produce a Diagnostic Trouble Code (DTC) depending on the type of fault present. Refer to the appropriate diagnostic procedures for EIS or PCM Drive Authorization System (DAS) related DTCs.
