CUSTOMER
SYMPTOM:

Customers may experience one or more of the following:
● The vehicle does not operate in electric mode.
● Reverse gear is not available.

CAUSE:

Various

GENERAL INFORMATION:
If on the vehicle scan report the error code P08F2 and/or P08F3 are active in the gearbox control unit, proceed
as described below.
NOTE: ● When DTC P08F3 is stored, the system activate the standby mode for the electric motor
(integrated in the dual-clutch transmission).
● This condition does not represent a mechanical failure condition for the gearbox, but
indicates that the electric motor inside the gearbox cannot be activated by the inverter;
consequently the TCM inhibits its use for safety reasons.
● The customer effect is a lack of traction or the possibility of moving the vehicle only
forwards, using only the odd gears. Even gears are not available because they are disabled
by the gearbox control unit, while reverse gear can be difficult to engage and the car may
not run smoothly.
● Based on that, the lack of traction is not related to an internal hardware problem of the
gearbox; therefore, it is not necessary to drain the oil or check for debris.
1. Check for other DTCs in:
• PCM (e.g. U0402-00: implausible data received from TCM).
• BPCM (e.g. P0C78: Hybrid/EV battery system pre-charge time "A" too long).
• HCP (e.g. P0A7D: low hybrid battery pack state of charge and/or P0AF8: hybrid/EV battery system voltage).
• APM (e.g. P2930: Hybrid/EV battery system pre-charge current "B" too high).
NOTE: The mentioned DTC errors ARE NOT NECESSARILY PRESENT AT THE SAME TIME.
2. Check the charge status of the 12V and 48V battery.
3. Check the wiring/connections by following the 12V and 48V circuit checklist at the end of this document.

4. If there is a DTC error after the wiring check, run the specific procedure of that DTC to resolve before
moving on to diagnosing for DTC P08F3:
4.1 if the error P0C0E-00 (Drive Motor B Inverter Power Supply Circuit/Open) is present in the HCP control
unit in the Active state, try to delete the errors and retest the vehicle. If the DTC is still present, replace the
inverter ONLY and check if the DTC is still present. If yes, replace the gearbox.
4.2. If DTC P0DA3-00 (Drive Motor "B" Inverter Voltage Sensor "A" Circuit) error is present in the HCP control
unit, proceed to replace ONLY the inverter and check if the DTC is still present. If yes, replace the gearbox.
4.3 In case DTC P0AF8 is present on HCP and DTC P08F2 is present on TCM, follow the related procedure
below.
4.4 In the event that DTC P0A7D is present on HCP and DTC P0C78 is present on BPCM and DTC P2930 is
present on APM, follow the related procedure below.
4.5 In the event that DTC P0AF8 is present on HCP and DTC P0C78 is present on BPCM, follow the related
procedure below.
4.6 For any other DTCs not mentioned, follow the specific diagnosis procedure.
5. If there is no DTC error, complete the P08F3 diagnosis procedure.
● DTC P0AF8 on HCP – P08F2 on TCM

Check the wiring between the 48V battery and the electric motor. The 330A fuse found on the wiring in a blue
box has two nuts. Check the tightness of the nuts.

There is no continuity, open circuit detected. The fuse has a darker side.

Check the connection between the wiring harness and the 48V battery. The connector nut on the positive
terminal of the 48V must be tightened.
