1. INSPECT IGNITION COIL AND SPARK TEST
(a) Check the DTCs.
NOTICE:
If a DTC is present, perform troubleshooting in accordance with a procedure for that DTC.
(b) Check that a spark occurs.
(1) Remove the 6 ignition coils (see page 18-7).
(2) Using a spark plug wrench 16 mm, remove the 6 spark plugs.
Torque: 25 NVm (250 kgfVcm, 18 ftVlbf)
(3) Install the spark plugs to each ignition coil, then connect the ignition coil connectors.
(4) Disconnect the 6 fuel injector connectors.
(5) Ground the spark plugs.
(6) Check that the spark plug occurs at each spark plug while the engine is being cranked.
NOTICE:

Be sure to ground the spark plugs when checking.

Replace the ignition coil if physical impact is felt.

Do not crank the engine for more than 2 seconds.
If a spark does not occur, perform the following test.
1 SPARK TEST
