1. What does U0064 mean?
U0064-87 has been reported in the Battery Energy Control Module (BECM) on certain Land Rover MHEV vehicles with “Stop Safely” and “Electric Charging fault” warnings. Land Rover documentation directs retailer diagnosis using the TOPIx workshop manual and collection of PMZ logs/TA evidence where applicable.
2. Technical explanation
Verified Land Rover manufacturer communications identify U0064-87 as a DTC that may be stored in the BECM. It is documented alongside U0120-00 and P0DA8-62 in reports of “Stop Safely” and “Electric Charging fault” messages. One communication concerning HV battery charging reports U0064-87 in the BECM and states the possible cause as software or electrical wiring continuity. Another communication for 2023-model-year-onward MHEV vehicles states that the cause of the warning-message condition was unknown and under investigation.
3. What system is affected?
Battery Energy Control Module (BECM). Manufacturer communications also reference the high-voltage battery charging system, High Voltage Junction Boxes (HVJBs), and the Belt Integrated Starter Generator (BISG) in different diagnostic guidance.
4. How serious is this code?
Not yet established by verified evidence. The documented warning messages include “Stop Safely” and “Electric Charging fault,” so prompt professional diagnosis is appropriate.
5. Symptoms you may notice
- “Stop Safely” warning message displayed on the Instrument Panel Cluster.
- “Electric Charging fault” warning message displayed on the Instrument Panel Cluster.
- High-voltage battery may not charge when the charging cable is connected to the vehicle.
6. Possible causes
- Software or electrical wiring continuity, according to SSM76039 for the no-charge condition with U0064-87 in the BECM.
- For the 2023-model-year-onward MHEV warning-message condition, the cause was documented as unknown and under investigation.
- Not yet established by verified evidence whether any one cause applies to an individual vehicle.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
A verified manufacturer communication reports that the high-voltage battery may not charge when the charging cable is connected. Whether a particular vehicle can charge is not established by the supplied evidence.
9. What you can safely do
- Arrange diagnosis by an authorized Land Rover retailer or qualified service facility using the applicable TOPIx workshop-manual procedures.
- Record the warning messages and whether charging fails, if this can be done without attempting repairs.
- Do not perform high-voltage component or wiring repairs yourself.
10. Step-by-step troubleshooting
- Continue diagnosis using the TOPIx workshop manual and applicable Helptext, as directed in Land Rover communications.
- For the HVJB-related no-charge condition, inspect and repair damaged wiring harnesses as necessary before renewing the HVJB, following the relevant workshop-manual procedures.
- For the MHEV warning-message condition, Land Rover directed collection of PMZ logs with original parts if the fault can be reproduced and addition of those logs to a Technical Assistance (TA) case.
- Where TA recommends it, renew the BISG. If the fault persists after BISG replacement, collect logs with the new part and share them on the TA, referencing the SSM and Engineering PTS_100 for further guidance.
11. When to contact service
Contact an authorized Land Rover retailer promptly, particularly if “Stop Safely” or “Electric Charging fault” is displayed, or if the vehicle will not charge. Ask the retailer to check BECM DTC U0064-87 and apply the applicable TOPIx and Land Rover SSM guidance.
12. What the service center may check
- Read stored BECM DTCs, including U0064-87 and the accompanying codes identified in the communication.
- Follow relevant TOPIx Workshop Manual Diagnosis and Testing/Helptext guidance.
- Assess wiring-harness condition where directed by the applicable no-charge diagnostic process.
- Collect PMZ logs and create or update a TA case where the applicable MHEV SSM process calls for it.
- Avoid HVJB replacement until the manufacturer-directed diagnostic steps have been completed.
13. Possible repair or resolution
- Repair damaged wiring harnesses as necessary when confirmed through the applicable diagnostic procedure.
- Renew the HVJB only after the specified diagnostic steps have been completed when applicable.
- Renew the BISG only if recommended through the TA process for the applicable warning-message condition.
- If the fault continues after BISG replacement, collect new logs and obtain further TA/Engineering guidance.
