Switch Monitor Test: Notes

WARNING: This page is about a different car, the 1992 Mercury Tracer, 1992 Ford Probe, and 1992 Ford Escort. However, it is still accessible from the selected car via links, so may be relevant.

Perform this test if no code is present after performing KOEO and KOER self-tests. Switch monitor tests determine if electrical signals to the ECA from input devices are correct. In this procedure, each device is tested individually. Perform test with SUPER STAR II tester or Analog Volt-Ohmmeter (VOM).
