CLEARING FAILURE CODES

Notice:To prevent Engine Control Module(ECM) damage, the key must be OFF when disconnecting or reconnecting
the power to the ECM (for example battery cable, ECM pigtail connector, ECM fuse, jumper cables, etc.)

Parameters listed in the table may not be exactly the same as your reading due to the type of instrument or other
factors. If a failure code is displayed during the “TROUBLE CODE” in scan tool check mode, check the circuit for
the code listed in the table below. For details of each code, turn to the page referred to under the “See Page” for
the re-spective “Failure Code” in the below table.

Failure codes should be cleared after repairs have been completed.

1F1-8 M162 ENGINE CONTROLS

This ignition system does not use a conventional
distributor and coil. It uses a crankshaft position
sensor input to the Engine Control Module (ECM). The
ECM then determines Electronic Spark Timing (EST)
and triggers the electronic ignition system ignition coil.

This type of distributorless ignition system uses a
‘‘waste spark” method of spark distribution. Each
cylinder is paired with the cylinder that is opposite it
(1-6 or 2-5 or 3-4). The spark occurs simultaneously in
the cylinder coming upon the compression stroke and
in the cylinder coming up on the exhaust stroke. The
cylinder on the exhaust stroke requires very little of
the available energy tofire the spark plug. The
remaining energy is available to the spark plug in the
cylinder on the compression stroke.

IGNITION SYSTEM

These systems use the EST signal from the ECM to
control the EST. The ECM uses the following
information:

•

Engine load (mass air flow sensor).

•

Engine temperature.

•

Intake air temperature.

•

Crankshaft position.

•

Engine speed (rpm).

IGNITION COIL

YAD1F090

The Electronic Ignition (EI) system ignition coil is located on the cylinder head cover. The double ended coils
receive the signal for the Engine Control Module (ECM) which controls the spark advance.

Each EI system ignition coil provides the high voltage to two spark plugs simultaneously;

T1/1: cylinder 2 and 5

T1/2: cylinder 3 and 4

T1/3: cylinder 1 and 6

The EI system ignition coil is not serviceable and must be replaced as an assembly.
