NOTE:
The communication between ECM, BCM and/or Intelligent Key unit uses the CAN communication sys-
tem.
ECM Re-Communicating FunctionBIS000YE
Performing following procedure can automatically perform re-communication of ECM and BCM or Intelligent
Key unit, but only when the ECM has been replaced with a new one (*1).
*1: New one means a virgin ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT-II is not necessary)
NOTE:
When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II
Operation Manual NATS.
If multiple keys are attached to the key holder, separate them before work.
Distinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Using a registered key (*2), turn ignition switch to “ON”.
*2: To perform this step, use the key that has been used before performing ECM replacement.
3. Maintain ignition switch in “ON” position for at least 5 seconds.
4. Turn ignition switch to “OFF”.
5. Start engine.
If engine can be started, procedure is completed.
If engine cannot be started, refer to CONSULT-II Operation Manual NATS and initialize control unit.

CONSULT-II.
2. Start engine and warm it up to the normal operating tempera-
ture.

FUEL INJECTORPFP:16600
Component DescriptionBBS005IG
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injec-
tor is energized. The energized coil pulls the ball valve back and
allows fuel to flow through the fuel injector into the intake manifold.
The amount of fuel injected depends upon the injection pulse dura-
tion. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

STARTING SYSTEM
STARTING SYSTEMPFP:23300
System Description BKS001ME
Power is supplied at all times:
through 40A fusible link (letter F , located in the fuse and fusible link block)
to ignition switch terminal 1,
through 15A fuse (No. 71, located in the IPDM E/R)
to CPU of IPDM E/R,
through 15A fuse (No. 78, located in the IPDM E/R)
to CPU of IPDM E/R.
With the ignition switch in the ON or START position, power is supplied:
[A/T models]
from ignition relay
through 10A fuse (No. 83, located in the IPDM E/R)
through IPDM E/R terminal 26
to park/neutral position switch terminal 1.
[CVT models]
through ignition relay ( within the IPDM E/R )
to CPU of IPDM E/R.
When the selector lever in the “P” or “N” position, power is supplied:
[A/T models]
through park/neutral position switch terminal 2
to IPDM E/R terminal 53.
[CVT models]
from TCM terminal 24
to IPDM E/R terminal 53.
Ground is supplied:
to IPDM E/R terminals 38, 50 and 60
from grounds E1 and E31.
Then starter relay is turn ON.
With the ignition switch in the START position, IPDM E/R is energized and power is supplied:
from ignition switch terminal 5
to IPDM E/R terminal 4 and
through IPDM E/R terminal 3
to starter motor terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.
