DTC

Description

P068A

ECM/PCM Power Relay De-Energized Performance
- Too Early

Technical Background
Current Engine/Motor Control Module (ECM) -J623- software incorrectly identifies main relay fault.

Production Solution
Improved Engine Control Module (ECM) software implemented.

Service
Update-Programming Procedure:
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.

WARNING:
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!

Note:
Prior to launching the ODIS Service diagnostic applications and starting control module update process,
confirm tester screen saver and power settings in accordance with Special Tools and Equipment - Service
Information Circular # VVT-12-02. 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 5054A 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.

Tip:
To Update the 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.
 Inspect the current Engine Control Module (ECM) Software Part No. and Version No., if the vehicle
does not have the latest Software Part No. and Version No., update the ECM using the SVM Unit code
as listed in the table below.
 If the Engine Control Module (ECM) Software Part No. and Version No. are at the latest level, this
bulletin does not apply. Further diagnosis is necessary.
