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.

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.

ASSEMBLY
Apply high-temperature grease to lubricate the bearing, gears and frictional surface when assembling the
starter.
Carefully observe the following instructions.
Pinion Protrusion Length Adjustment
CLEARANCE (VQ23DE AND VQ35DE MODELS)

With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance “L” between the front
edge of the pinion and the pinion stopper.

Not in the specified value... Adjust by adjusting plate.
MOVEMENT (QR20DE MODELS)

Compare movement “L” in height of pinion when it is pushed out
with magnetic switch energized and when it is pulled out by
hand until it touches stopper.

Not in the specified value... Adjust by adjusting plate.Clearance “L” : Refer to SDS. SC-38, "
Starter" .
