HOW TO PERFORM FOR SYSTEM INSPECTION
This inspection procedure is a simple troubleshooting which should be carried out on the vehicle during
system operation and is based on the assumption of system component trouble
Always inspect the trouble taking the following items into consideration:

Ground point fault

Open or short circuit of the wire harness

Connector or terminal connection fault

Fuse or fusible link fault
NOTICE:

This is an on±vehicle inspection during system operation.
Therefore, inspect the trouble with due regard for safety.

If connecting the battery directly, be careful not to cause a short circuit, and select the applicable
voltage.
1. Voltage Check
(a)Establish conditions in which voltage is present at the
check point.
Example:
[A] ± Ignition SW on
[B] ± Ignition SW and SW 1 on
[C] ± Ignition SW, SW 1 and Relay on (SW 2 off)
(b)Using a voltmeter, connect the negative (±) lead to a
good ground point or negative (±) battery terminal
and the positive (+) lead to the connector or
component terminal. This check can be done with a
test bulb instead of a voltmeter.
2. Continuity and Resistance Check
(a)Disconnect the battery terminal or wire so there is no
voltage between the check points.
(b)Contact the two leads of an ohmmeter to each of the
check points.

Wire Harness Repair Manual (RM1022E)
If the circuit has diodes, reverse the two leads and check
again.
When touching the negative (±) lead to the diode positive
(+) side and the positive (+) lead to the negative (±) side,
there should be continuity. When touching the two leads in
reverse, there should be no continuity.
HINT: Specifications may vary depending on the type of
tester, so refer to the tester's instruction manual before
performing the inspection.
Check LED (Light Emitting Diode) in the same manner as
that for diodes.
HINT:

Use a tester with a power source of 3V or greater to
overcome the circuit resistance.

If a suitable tester is not available, apply battery
voltage and check that the LED lights up.
(c)Use a volt/ohmmeter with high impedance (10kW/V
minimum) for troubleshooting of the electrical circuit.
3. Bulb Check
(a)Remove the bulb.
(b)There should be continuity between the respective
terminals of the bulb together with a certain amount
of resistance.
(c)Apply the two leads of the ohmmeter to each of the
terminals.
(d)Apply battery voltage and check that the bulb light up.

Wire Harness Repair Manual (RM1022E)
CIRCUIT PROTECTION
All electrical circuits are protected against excessive loads which might occur because of shorts or
overloads in the wiring system. Such protection is provided by a fuse, circuit breaker, or fusible link, A
short circuit may cause a fuse to blow or a circuit breaker to open.
RESET CIRCUIT BREAKER
1. Remove Circuit Breaker
(a)Disconnect the negative (±) cable from the battery.
(b)Remove the circuit breaker.
2. Reset Circuit Breaker
(a)Insert the needle into the reset hole and push it.
(b)Using an ohmmeter, check that there is continuity
between both terminals of the circuit breaker.
If continuity is not as specified, replace the circuit breaker.
HINT: If replacing the circuit breaker, be sure to replace
it with a breaker with an equal amperage rating.
3. Install Circuit Breaker
(a)Install the circuit breaker.
(b)Connect the negative (±) cable to the battery.
HINT: If a circuit breaker continues to cut out, a short
circuit is indicated. Have the system checked by a qualified
technician.

4. As some tachometers are not compatible with this igni-
tion system, we recommend that you confirm the
compatibility of your unit before use.
5. NEVER allow the tachometer test probe to touch ground
as this could damage the igniter and/or ignition coil.
6. Do not disconnect the battery when the engine is run-
ning.
7. Check that the igniter is properly grounded to the body.
PRECAUTIONS
1. Do not leave the ignition switch on for more than 10
minutes if the engine will not start.
2. (3S±FE)
When a tachometer is connected to the system, con-
nect the test probe of the tachometer to service con-
nector of the distributor.
3. (2VZ±FE)
When a tachometer is connected to the system, con-
nect the test probe of the tachometer to terminal IG E)

SPARK TEST
CHECK THAT SPARK OCCURS
(a) Disconnect the high±tension cords from the spark plugs.
(b) Remove the spark plugs.
(c) Install the spark plugs to each high±tension cord.
(d) Ground the spark plug.
(e) Check if spark occurs while engine is being cranked.
HINT: To prevent gasoline from being injected from injectors
during this test, crank the engine for no more than 1
± 2 seconds at a time.
If the spark does not occurs, perform the test as follows:
