To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.
(1)
Connect scan tool MB991958 to the data link connector.
(2)
Turn the ignition switch to the "ON" position.
(3)
Carry out the test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 24 P.
13Ab-8.
(4)
Check the diagnosis trouble code (DTC).
Q:Is DTC P02253 set?
YES:
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.
NO:
It can be assumed that this malfunction is
intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.
DTC P2423: HC adsorber (HC trap catalyst) efficiency below threshold
M11310100396USA0000010000
TECHNICAL DESCRIPTION
After the fuel cut-off during the deceleration, the rich
control is performed. Depending on the point of time
when the catalyst releases Oxygen which is
temporarily absorbed by the lean control, the HC
adsorber (HC trap catalyst) within center exhaust pipe
is judged on its deterioration in performance.
DESCRIPTIONS OF MONITOR METHODS
When the difference in the s witching time into the rich
control is below the specified time between the heated
(rear) oxygen sensor and the center exhaust pipe
heated oxygen sensor, it is judged that a malfunction
exists.
MONITOR EXECUTION
Once per driving cycle

DIAGNOSTIC TROUBLE CODE PROCEDURES
⦆
The fuel shut-off mode continues for 3 seconds or
more.
⦆
After the fuel shut-off mode is terminated, the output
voltage of the center exhaust pipe heated oxygen
sensor is0.2 V or less for 5 seconds.
Judgment Criterion
⦆
After the output voltage of the rear heated oxygen
sensor reaches 0.6 V, the output voltage of the
center exhaust pipe heated oxygen sensor reaches
0.6 V within 1.5 seconds.
