The PCM energizes the injectors in a sequential
order during all engine operating conditions except
start-up. For the first injector pulse width during
start-up, all injectors are energized at the same time.
Once the PCM determines crankshaft position, it
begins energizing the injectors in sequence.
IGNITION COIL—PCM OUTPUT
The coil assembly consists of independent coils
molded together (Fig. 29) or (Fig. 30). The coil assembly
is mounted on the intake manifold. High tension leads
route to each cylinder from the coil. The coil fires two
spark plugs every power stroke. One plug is the cylin-
der under compression, the other cylinder fires on the
exhaust stroke. The PCM determines which of the coils
to charge and fire at the correct time.
The Automatic Shutdown (ASD) relay provides bat-
tery voltage to the ignition coil. The PCM provides a
ground contact (circuit) for energizing the coil. When
the PCM breaks the contact, the energy in the coil pri-
mary transfers to the secondary causing the spark. The
PCM will de-energize the ASD relay if it does not
receive the crankshaft position sensor and camshaft
position sensor inputs. Refer to Automatic Shutdown
(ASD) Relay—PCM Output in this section for relay
operation.
MALFUNCTION INDICATOR (CHECK ENGINE)
LAMP—PCM OUTPUT
The PCM supplies the malfunction indicator (check
engine) lamp on/off signal to the instrument panel
through the CCD Bus. The CCD Bus is a communi-
cations port. Various modules use the CCD Bus to
exchange information.
The Check Engine lamp comes on each time the
ignition key is turned ON and stays on for 3 seconds
as a bulb test.
The Malfunction Indicator Lamp (MIL) stays on
continuously, when the PCM has entered a Limp-In
mode or identified a failed emission component. Dur-
ing Limp-in Mode, the PCM attempts to keep the
system operational. The MIL signals the need for
immediate service. In limp-in mode, the PCM com-
pensates for the failure of certain components that
send incorrect signals. The PCM substitutes for the
incorrect signals with inputs from other sensors.
If the PCM detects active engine misfire severe
enough to cause catalyst damage, it flashes the MIL.
At the same time the PCM also sets a Diagnostic
Trouble Code (DTC).
For signals that can trigger the MIL (Check
Engine Lamp) refer to Group 25, On-Board Dianos-
tics.
The MIL can also display diagnostic trouble codes.
Cycle the ignition switch on, off, on, off, on, within 5
seconds and any diagnostic trouble codes stored in
