Alignment of DME-EWS 

For vehicles equipped with DME control modules after 1/95 production, the ISN of a replacement control module must be aligned with the EWS control module.

This procedure copies the ISN from the new DME control module and installs it into the EWS control module. If this procedure is not carried out the engine will crank, but will not start.

Interrogate the DME fault memory and clear any faults stored during the programming process.
