CAUSE
JBE (Junction Box Electronics) software error
PROCEDURE
Do not replace any parts.
1. Perform a vehicle test using the latest ISTA (Integrated Service Technical Application) diagnostic software.
Note: When the ISTA system message displays:
"Battery voltage only "XX.XX" V. Please connect charger."
Please note the displayed battery voltage reading in the repair order comments section.
2. If ISTA is able to communicate with the vehicle, complete all relevant test plans related to the fault symptoms.
3. If ISTA will not communicate with the vehicle and the battery is accessible, perform a battery reset for approximately 30 minutes.
4. If ISTA will not communicate with the vehicle and the battery is not accessible in the trunk or cargo area, disconnect the JBE for approximately 30 minutes.
Refer to ISTA Repair Instructions "Removing and installing or replacing junction box electronics".
5. After the battery reset (Step 3) or the JBE remove and reinstall procedure (Step 4), check the operation of all functions that were inoperable and repeat Steps 1 and 2 as necessary.
6. [NEW] Program the vehicle using ISTA/P (Integrated Service Technical Application, programming) 2.47.2 or later.
[NEW] Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the latest software.
[NEW] For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal / Service / Workshop Technology / Vehicle Programming.
