<Applicable

model>

During  forced  rich  control,
time difference is monitored
between  two  points:  from
when heated oxygen sensor
(rear) is switched to "rich" to
when  center  exhaust  pipe
heated  oxygen  sensor  is
switched to "rich".

× 1 msec

NOTE:

*1: Minimum value: The test fails if test value is

less than this value.

NOTE:

*2: Maximum value: The test fails if test value is

greater than this value.

NOTE:

When not finishing the monitor of the driving cycle

for the request of On-Board Monitoring Test Request, the ECM
outputs the stored latest monitor test result.

NOTE:

When the monitored test results are erased by the

battery disconnection and so on, the ECM outputs the values
in hexadecimal of "0000" or "FFFF", otherwise it outputs
abnormal values and so on. In case of this, the ECU outputs
are handled as invalid-values. When the first monitor
(Readiness Status) is completed after this, the ECM outputs
the valid-values.

NOTE:

"Test Limit Type & Component ID byte" output from the

ECM is given in hexadecimal of "00" or "80". "00" means the
maximum value and "80" means the minimum value.

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

NOTE:

When mode II is selected with MB991958, the

Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check
Engine Lamp) will light when the engine control module (ECM)
first detects the trouble (Note that this is only for
emission-related trouble). At the same time, the relevant
diagnostic trouble codes will be registered. In respect to
the comprehensive component electrical faults (opens/
shorts), the time for the diagnostic trouble code to be
registered after the fault occurrence is four seconds → one
second. Therefore, the confirmation of the trouble symptom
and the confirmation after completing repairs can be
reduced. To return to the normal mode I after mode II has
been selected once, the ignition switch must be turned "OFF"
once or mode I must be reselected with the scan tool
MB991958. The diagnostic trouble code, system readiness
test status and freeze frame data, etc., will be erased when
mode I is returned to, so record these before returning to
mode I.

Connect scan tool MB991958 to the data link connector.

Turn the ignition switch to the "ON" position.

Change the diagnostic test mode of the powertrain control
module to DIAGNOSTIC TEST MODE II (INCREASED
SENSITIVITY).

Road test the vehicle.

Read the diagnostic trouble code and repair the
malfunctioning part.

Turn the ignition switch to the "LOCK" (OFF) position.

Disconnect scan tool MB991958 from the data link connector.

ON-BOARD DIAGNOSTICS

The engine control module (ECM) monitors the input/
output signals (some signals all the time and others
under  specified  conditions)  of  the  ECM.  When  a
malfunction continues for a specified time or longer
after the irregular signal is initially monitored, the ECM
judges that a malfunction has occurred. After the ECM
first detects a malfunction, a diagnostic trouble code
is recorded when the engine is restarted and the same
malfunction  is  re-detected.  However,  for  items
marked  with  a  "*",  a  diagnostic  trouble  code  is
recorded  on  the  first  detection  of  the  malfunction.
There are 164 diagnostic items. The diagnostic results
can be read out with a scan tool. Since memorization
of the diagnostic trouble codes is backed up directly
by the battery, the diagnostic results are memorized
even if the ignition key is turned off. The diagnostic
trouble  codes  will,  however,  be  erased  when  the
battery  terminal  or  the  ECM  connector  is

disconnected. In addition, the diagnostic trouble code
can also be erased by turning the ignition switch to ON
and sending the diagnostic trouble code erase signal
from scan tool MB991958 to the ECM.

NOTE:

If the sensor connector is disconnected

with the ignition switch turned on, the diagnostic
trouble code is memorized. In this case, send the
diagnostic trouble code erase signal to the ECM in
order to erase the diagnostic memory. The 164
diagnostic items are all indicated sequentially
from the smallest code number. The ECM records the
engine operating condition when the diagnostic
trouble code is set. This data is called "Freeze-
frame" data. This data can be read by using the
scan tool, and can then be used in simulation
tests for troubleshooting. Data items are as
follows:

NOTE:

If the ECM detects multiple malfunctions,

the ECM stores the "Freeze-frame" data for only

DIAGNOSTIC FUNCTION

the first item that was detected. However, if the
ECM detects a misfire or a fuel system
malfunction, the ECM stores the data by giving
priority to the misfire or fuel system

malfunction, regardless of the order in which the
malfunction was detects

NOTE:

As for Diagnostic trouble code P1603,

"Freeze-frame" data is not memorized.
