Reason For Update
Original publication.
Customer states MIL-ON with P0456 found in the Engine/Motor Control Module -J623-.
Technical background
The following fault code must be stored in the Engine/Motor Control Module -J623- (ECM) Fault Memory:
DTC
Description
P0456
EVAP Emission Contr. Sys. (very small leak) Leak Detected
NOTICE
DO NOT diagnose or replace components before performing the procedure below.
Production change
Updated Engine/Motor Control Module -J623- software introduced in production.
Measure
MY-2022-23: PROCEED TO STEP 1
MY-2024 ONLY: PROCEED DIRECTLY TO STEP 3
STEP 1: Check currently installed software part # and version against table below.
If necessary, perform update found in Step 2. If vehicle software is already up to date, proceed to Step 3.
STEP 2: Update-Programming Procedure:
WARNING
Critical Warning: The Midtronics battery charger must be connected to the vehicle battery for the duration of the
programming, to ensure the battery state of charge remains above 12.5 volts during the update process. If the battery
drops below 12.5 volts, the programming could fail which may result in damage to the control module. Control modules
damaged by inadequate voltage will not be covered under the warranty policy. The technician should verify the vehicle
voltage prior to starting the update process, and should monitor the voltage for the duration of the update.
– The pr may cancel itself if the hazard warning lights are not switched ON. The hazard warning lights prevent the system
from switching to bus sleep mode during the update procedure.
– ODIS-Service Service tester should be updated to the latest GFF technical version 25.0.2 or higher and SW version
2.53.1 or higher
CAUTION
Radiator Fan(s) may cycle ON high speed during the Update Process! There is a risk that personal injury may result if
contact is made with spinning fan blades.
– Keep hands and all objects away from Radiator Fan(s) during Update Process.
NOTICE
Prior to launching the ODIS Service diagnostic applications and starting control module update process, confirm tester
screen saver and power settings in accordance with Diagnostic Device Hardware & Windows® - VHW-20-02 Change Power
Options After Windows®10 Upgrade. Failure to do so may result in the tester entering power save mode during data
transfer, and subsequent control module failure. When using a VAS 6150/X or 6160/X tester in conjunction with a VAS 6154
wireless transmitter head for a flash procedure, connect a USB cable between the transmitter head and the tester. Failure
to do so may lead to errors during the flash procedure.
– VAS tools must only be used with their power adapters plugged in. Under no circumstances should they be used on
battery power alone during the programming procedure.
To Update- Programming using Software Version Management (SVM), review and follow instructions in Technical Bulletin
Instance 2014603 “Software Version Management”.
The SVM process must be completed in its entirety so the database receives the update confirmation response. A warranty
claim may not be reimbursed if there is no confirmation response to support the claim or action is carried out that is not
explicitly stated in the Technical Bulletin.
Update the Engine/Motor Control Module -J623- using the SVM Unit code as listed in the table below:
