SITUATION
• Vehicle will not go into “eDrive”
• No pertinent electric drivetrain fault codes to assist with diagnosis
• “eDrive” may be greyed-out in the Central Information Display (CID) and is not selectable

CAUSE
• MSA deactivation
• 12 Volt battery failure
• Intelligent Battery Sensor (IBS) failure

CORRECTION
MSA Activation (brand new vehicles or vehicles with extremely low mileage).
In other cases, “eDrive” does not function because of a faulty 12 Volt battery or IBS, but the battery sensor
does not set any faults to indicate the problem. The procedure steps below (starting at Step 2) provide a
general diagnostic plan for these situations.

PROCEDURE
Important Warning: Only properly trained personnel, who have passed all applicable technical training
courses, should perform any maintenance or repairs on any Hybrid or Electric Vehicle. Work performed by
unqualified persons may result in severe injury, or damage to the vehicle. Additional information may be
found in REP 61 00… “Observe safety instructions when handling electric vehicles”.
Note: In extreme temperatures (both hot and cold) “Max eDrive” may not be available, and drive range may
be displayed as “---“. In these situations, bringing the battery to a more nominal temperature will resolve the
symptoms. This can be accomplished by pre-conditioning the battery or simply running the vehicle to allow it
to regulate the battery temperature itself. This is normal operating strategy.
1. Check MSA activation.
Is MSA activated on the vehicle?
YES - go to Step 2.
NO - follow one of the two methods below to activate MSA, depending on which is more appropriate.
MSA Activation - Service Module:
A. Select the service functions in ISTA NEXT.

Path:
- Drive
- Engine electrical system
- Automatic engine start-stop function
- Deactivating the MSA installation mode
B. Run the following test module:
ABL-DIT-AS1365_MSAMOM: Deactivate installation mode.
MSA Activation – Test Module:
A. Access the test module via the function structure and call up the perceived symptom in ISTA NEXT.
Path:
- Drive
- Hybrid vehicle
- Current fault patterns
- Electric driving not possible
B. Run the following test module:
ABL-DIT-AW1365_EDRV_MSA_DEAK – MSA or electric driving not possible.
2. Perform a Midtronic test on both 12 volt batteries and replace as indicated.
Note: Prior to replacing 12 Volt batteries, remember to perform the Energy Diagnosis test plan (See
SI B61 13 05) to diagnose and identify if there are any other underlining condition that also need to
be addressed on the vehicle.
3. Recheck eDrive.
Is “eDrive” functioning correctly?
YES - release the vehicle.
NO - go to next step.
4. Check the wiring, connections, pins etc. of the IBS on the main and auxiliary 12 Volt batteries.
Were any wiring problems found?
YES - repair any wiring issues found. Go to next step.
NO - replace the IBS on the auxiliary battery. Go to next step.
5. Recheck eDrive.
Is “eDrive” functioning correctly?
YES - release the vehicle.
NO - go to next step.
6. Replace the IBS on the main 12 Volt battery.
7. Recheck eDrive.
Is “eDrive” functioning correctly?
YES - release the vehicle.
NO - submit a PuMA case for further assistance.
