EI System High Data Rate: Notes

NOTE: Start all diagnostics with QUICK TEST. See appropriate TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section. These tests are dependent on results and service 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 -9 when using pinpoint test procedures.
