Technical Background Diagnostic Trouble Code/s (DTC’s) stored in the Battery Energy Control Module 2 (Super capacitor) The following DTC’s relating to Hybrid EV Battery Temp Sensor system faults can be logged either individually or combined - P0A1F00 - P0A9E00 – P0AC800 - P0ECA00 The Super capacitor part number must be checked, should the part numbers be as shown below and the symptoms/DTC’s are as previously described please carry out the instructions within the Measure section of this TPI Should the part number be different from the numbers shown below and the symptoms and/or the DTC’s are not as previously described – Please raise a DISS query • 4M0.915.169.C • 4M0.915.169.D • 4M0.915.169.E Following a successful update, the part number will change to 4M0.915.169.F with Software version 114 Production Solution All VIN’s post SJAAF14V6JC021273 have the latest specification Super capacitor fitted Service 1. Ensure a suitable battery charger is correctly connected to the vehicle electrical system for the duration of this procedure Figure 1 2. Ensure the ignition key is located in the remote control key reader and switch on the ignition (see Figure 1) 3. Connect the Bentley approved diagnostic tool to the vehicle On Board Diagnostic (OBD) socket. NOTE: The process is Initiated via Bentley diagnostic tool (VAS 6150C or similar) using a hard wire connection to the vehicle OBD socket, Bluetooth connections should not be used Your Bentley diagnostic tester must be loaded with Bentley Brand Diagnostic Data Version 2.24.7 or higher 4. From the diagnostic tool main desktop select Off board Diagnostic Information System 5. Select – Start diagnosis 6. Select – Model / Engine 7. Select guided fault finding to check and clear the vehicle of any fault codes. NOTE: At this stage when requested to make a Target/Actual comparison do not perform this action select NO Figure 2 8. Referring to Figure 2, Select Special functions (1), Select SVM – Problem related Hardware/Software Update (2), Select Perform test (3) Figure 3 9. Referring to Figure 3, at the SVM screen (1) enter the specific SVM code 4V021TPIUPDATE02 and then select Adopt (2) 10. Referring to Figure 4, Check you have entered the correct SVM code (1) and select Yes (2) 11. When prompted enter your global user ID and password 12. Follow the on screen prompts to continue through the procedure, identification data will be transferred 13. Once software that requires changing is detected select Done/Continue - Follow all onscreen prompts, the online connection will deliver the required software to the tester Figure 4 14. Select Yes at Update programming 21 to update 21 – Battery Energy Control Module 2 (see Figure 4 point 1) 15. During update a progress bar will be displayed 16. Once the battery energy control module 2 is updated an automatic SVM will take place Figure 5 17. Select Done/Continue at successfully complete to finalise the update (see Figure 5) 18.
