TEST PROCEDURE 5 – Key Switch (Start Circuit)
See General Warnings on page 1-2.
NOTE: This is a voltage test.
The key switch provides power and KEY INPUT to the ECU.
1. If necessary, see Testing Basics on page 18-10.
2. Remove instrument panel to access the back of the key switch but do not disconnect wires. See Instrument
Panel Removal, Section 4, Page 4-7.
3. With the key switch in the OFF position:
– The red wire should show battery voltage coming to the switch.
– The blue wire should show zero (0) volts. If it shows battery voltage, the switch has failed CLOSED and
must be replaced.
4. With the key switch in the ON position:
– The blue wire should show battery voltage passing through the key switch to a sonic weld in the instrument
panel harness, the 9-pin connector, sonic weld_3, the 5-amp fuse, the solenoid, and the 4-pin connected car
plug. If it does not show battery voltage, the switch has failed OPEN and must be replaced.
TEST PROCEDURE 6 – Key Switch (Engine Kill Circuit)
See General Warnings on page 1-2.
NOTE: This is a continuity test.
1. If necessary, see Testing Basics on page 18-10.
2. Disconnect battery and spark plug wire(s).
See Disconnecting the Battery- Gasoline Vehicles on page 1-3.
3. Remove the instrument panel. See Instrument Panel Removal, Section 4, Page 4-7.
4. Disconnect wires from the (+M) and (–M) terminals of the key switch (Figure 18-3, Page 18-20) .
5. Place the red (+) probe on the (+M) terminal and the black (–) probe on the (–M) terminal. With the key switch
OFF, the reading should be continuity. With the key switch ON, the reading should be no continuity. If either
reading is incorrect, replace the key switch.
6. Connect wires to the key switch. Make sure wires are connected correctly and are tight. If they are not, rewire
or tighten as necessary.
7. Install dash panel in reverse order of removal.
