EI System High Data Rate: Notes

WARNING: This page is about a different car, the 1995 Ford Explorer and 1995 Ford Aerostar. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Start all diagnostics with QUICK TEST. See TESTS W/CODES - EEC-IV (4.0L) article. These tests are dependent on results and diagnostic trouble codes received during QUICK TEST.

NOTE: EI Diagnostic Cable (Rotunda 007-00059) should be used to diagnose this system. This cable is equipped with additional circuits and components used to enhance and modify signals for testing purposes. If an aftermarket test cable is used or diagnosis is being performed using only a DVOM, become familiar with system wiring diagram and system operation.

NOTE: Refer to Figs. Figure -8 when using pinpoint test procedures.
