Tip:
Do not end the diagnostic session during the process. Work through all steps in the same Diagnostic session so the
faults and test plans are not lost.
If the above concern has been confirmed with one or more of the above DTCs perform the following:
• Read all instructions in this Technical Bulletin before starting the repair procedure to understand the steps that
have to be performed.
• Start Guided Fault Finding diagnosis and allow the system to calculate the test plans according to the fault
entries.
• Proceed with the SVM update procedure as follows below.
Note:
Before this SVM update is started the High Voltage System must be De-energized according to the scan tool
directions.

SVM Update Instructions
1. Follow all instructions in TSB 2011732: 00 Software Version Management (SVM), operating instructions.
2. Update the Hybrid Battery Management (J840) using the SVM action code as listed in the table below, if
necessary:
