EWS II

DIAGNOSIS

The DIS is used to diagnose and troubleshoot problems with the EWS II system operation. The EWS II system must be considered whenever There is a problem that relates to the starting of the vehicle.

Always follow the procedures found in the "FAULT SYMPTOM TROUBLESHOOTING PROCEDURES" section of the DIS specific to the fault symptom.

The following points must also be considered:
- Power and grounds to the EWS II and Transmitter/Receiver modules.
- Has the DME control module been replaced and has the ISN number been transferred to the EWS II control module?
- Is There a circuit problem between the EWS II control module and the starter?
- Is There a circuit problem between the EWS II and DME control modules?
- Is the key being used to start the vehicle recognized as a valid key by the EWS II?

The MoDiC and the latest programming software are the only method of synchronizing a new DME with an existing EWS II. The information on MoDiC software will be provided through the IDC Bulletins as the software is developed.
