GASOLINE VEHICLE - TROUBLESHOOTING
AND ELECTRICAL SYSTEM Test Procedures

TEST PROCEDURE 3 – Ground Cables
See General Warnings on page 1-2.
NOTE: This is a continuity test for the main ground wire of the vehicle. An additional ground wire is located on top
of the fuel tank.
1. If necessary, see Testing Basics.
2. Disconnect battery and spark plug wire.
3. Check the following wires and cables for clean, tight connections and continuity:
– Check the starter/generator ground cable (black wire) from A1 terminal to chassis or engine.
– Check the engine ground cable from engine block to negative (-) main harness lead disconnected from battery.
– Check the ground cable from main harness to negative (-) main harness lead disconnected from battery.
– Disconnect voltage regulator from main harness. Check from black wire in 3-pin connector to negative (-)
main harness lead disconnected from battery. This will test sonic weld _18 and sonic weld _1 in the main
wire harness.
4. The reading should be continuity. If the reading is incorrect, clean and tighten cable connections. If the
connections are good and the reading is incorrect, repair or replace the wire or cable.
TEST PROCEDURE 4 – 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.
2. Remove the instrument panel. Do not disconnect the wires.
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. If it does not show battery voltage, the switch has failed OPEN
and must be replaced.
TEST PROCEDURE 5 – Key Switch (Engine Kill Circuit)
NOTE: This is a continuity test.
1. If necessary, see Testing Basics.
2. Disconnect battery and spark plug wire.
3. Remove the instrument panel. See Instrument Panel Removal.
4. Disconnect the wires from the (+M) and (–M) terminals of the key switch.
5. Set the multimeter to 200 Ohm (1) (Figure 18-3, Page 18-12) .
