Testing for Continuity in a Switch

continuity function detects opens or shorts as fast as 1
millisecond. This can be a valuable trouble-shooting aid
when looking for intermittents associated with cables,
connections, switches, and relays.
1. Insert test leads in the input terminals shown in Figure
19.
Turn rotary switch to N.
2.
Press the E button.

4. Connect probes to stoplight switch.
5. Press brake pedal and listen for tone. If tone sounds,
stoplight switch is good.
