Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 4.

NO:

The inspection is complete.

STEP 4. Test the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 20 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0506 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.

DTC P0507: Idle Control Sytem RPM Higher Than Expected

M11310100239USA0000010000

TECHNICAL DESCRIPTION

｠

The amount of air taken in during idling is regulated
by the opening and closing of the throttle valve.

engine speed and the target engine speed.

DESCRIPTIONS OF MONITOR METHODS
Difference between actual and target idle speed is
over the specified value.

Judgement Criterion

｠

Actual idle speed has continued to be higher than
the target idle speed by 200 r/min (300 r/min*) or
more for 12 seconds.

*: Specs in parentheses are applicable if the
maximum air temperature during the previous
operation was more than 45°C (113°F).

DTC P0513: Immobilizer Malfunction

M11310100240USA0000010000

TECHNICAL DESCRIPTION

｠

ECM  monitors  the  communication  condition  with
the  immobilizer-ECU.  When  an  abnormality  in
communication  is  found,  ECM  prevents  engine
start.

DTC SET CONDITIONS

Check Condition

｠

Ignition switch: ON

Judgment Criterion

｠

When the communication error between ECM and
the immobilizer-ECU continues for 2 seconds or
more.

｠

When it was different in the encrypted code sent
from immobilizer-ECU and operation result by
ECM.

TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)

｠

Malfunction of CAN system.

｠

Malfunction of immobilizer system.

｠

ECM failed.
