SYSTEM READINESS TEST STATUS

PURPOSE
The Readiness function (also referred to as I/M
Readiness or I/M Flags) indicates if a full diagnostic
check has been "Completed" (is "Ready") for each
non-continuous monitor. Enhanced I/M State
Emission Programs will use the Readiness status
(Codes) to see if the vehicle is ready for OBD-II
testing. "Incomplete" (Not Ready) codes will be one of
the triggers for I/M failure.

MULTIPORT INJECTION SYSTEM (MFI) <DIAGNOSIS>

DIAGNOSTIC FUNCTION

OVERVIEW
The ECM monitors the following main diagnosis items
and records whether the evaluation was completed or
is incomplete. The Readiness Codes are established
for the I/M programs, thereby confirming that the
vehicles have not been tampered with by erasing the
diagnostic trouble code(s) (DTCs) before I/M testing.
The Readiness Codes and DTCs can be reset by
disconnecting the battery or by erasing the codes with
a scan tool MB991958 (M.U.T.-III sub assembly). For
this reason, all the Readiness Codes must be
displayed "Complete" before I/M testing.
When the monitors run and complete, the scan tool
MB991958 (M.U.T.-III sub assembly) will display the
Readiness Codes as "Complete" (General Scan
Tools display as "Ready"). When the vehicle is
operating normally and the OBD-II Drive Cycle is
carried out, the Readiness Codes will be set as
"Complete" on the first drive cycle. For DTCs requiring
two drive cycles to detect a fault, the second drive
cycle is required to set the Readiness Codes as

"Complete" if a fault is detected during the first drive
cycle. If the fault is still there after the second drive
cycle, a DTC will be set.

EGR system: P0401

After all the Readiness Codes are displayed as
"Complete", the technician is assured that any DTCs
related to the monitor will be displayed if the system
has a problem. That is why some State's I/M programs
require the Readiness Code as "Complete" before
they check for DTCs.

NOTE:

After a repair is made for a DTC, the

technician should drive the OBD-II Drive Cycle
checking that the scan tool MB991958 (M.U.T.-III
Sub Assembly) displays all the Readiness Codes as
"Complete".

When the main sensor malfunctions are detected by
the diagnostic test mode, the vehicle is controlled by
means of the following defaults.

MALFUNCTION ITEM

CONTROL CONTENTS DURING MALFUNCTION

Mass airflow sensor

｠

Uses the throttle position sensor signal and engine speed signal (crankshaft
position sensor signal) for basic injector drive time and basic ignition timing
from the pre-set mapping.

Intake air temperature
sensor

Controls as if the intake air temperature is 25°C (77°F).

Engine

coolant

temperature sensor

Controls as if the engine coolant temperature is 80°C (176°F). (This control will
be continued until the ignition switch is turned to "LOCK" (OFF) position even
though the sensor signal returns to normal.)

Camshaft position sensor Injects fuel simultaneously into all cylinders. (After the ignition switch is turned

to "ON" position, the No.1 cylinder top dead center is not detected at all.)

Barometric

pressure

sensor

Controls as if the barometric pressure is 101 kPa (30 in.Hg).

Knock sensor

Switches the ignition timing from ignition timing for high octane to ignition timing
for standard octane fuel.

Heated oxygen sensor
front

Air/fuel ratio closed loop control is not performed.

Heated oxygen sensor
rear

Performs the closed loop control of the air/fuel ratio by using only the signal of
the heated oxygen sensor (front) installed on the front side of the catalytic
converter.
