1.INSPECT IGNITION COIL (WITH IGNITER) AND SPARK TEST
(a)Check for DTCs.
NOTICE:
If DTC is present, perform a troubleshooting in accordance with a proced\
ure for that DTC.
(b)Check that spark occurs. (1)Remove the cylinder head cover No. 2. (See page 14±6)
(2) Remove the ignition coils (with igniter).
(3) Using a 16mm (0.63 in) plug wrench, remove the spark plugs.
(4) Install the spark plugs to each ignition coil (with igniter) and connect the \
ignition coil connectors.
(5) Disconnect the 4 injector connectors.
(6) Ground the spark plugs.
(7) Check if spark occurs at each spark plug while engine is being cranked.
NOTICE:
Be sure to ground the spark plug when checking.
Replace the ignition coil it is given physical impact.
Do not crank the engine for more than 2 seconds.
If the sparks do not occur, do the following test:

.
(b) Start the engine and check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the charge warn\
ing light circuit. 8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) According to the following procedure, connect an amme-
ter and voltmeter as shown in the illustration.
(1) Disconnect the wire from terminal B of the generatorand connect it to the negative (±) lead of the amme-
ter.
(2) Connect the positive (+) lead of the ammeter to ter- minal B of the generator
(3) Connect the positive (+) lead of the voltmeter to ter- minal B of the generator.
(4) Ground the negative (±) lead of the voltmeter.
(b) Check the charging circuit. (1) Keep the engine speed at 2,000 rpm, check thereading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 12.9 to 14.9 V
HINT:
If the voltmeter reading is more than standard voltage, re-
place the voltage regulator.
If the voltmeter reading is less than the standard voltage,
check the voltage regulator and generator as follows:
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) Keep the engine speed at 2,000 rpm, turn on the high beam headlights and\
turn the heater blower switch to the ºHIº position.
(b) Check the reading on the ammeter. Standard amperage: 30 A or more
HINT:
If the ammeter reading is less than standard amperage, repair the genera\
tor.
If the battery is fully charged, the indication will sometimes be less t\
han standard amperage.
