1. What does P303F mean?
For certain 2019–2021 Jaguar I-Pace vehicles in the US, P303F may be stored with a front Electric Drive Unit (EDU) parking-lock actuator wiring concern. The verified Jaguar/NHTSA communication identifies possible P303F-15 and P303F-29 variants.
2. Technical explanation
The supplied official manufacturer communication describes a lack of retention at the front EDU that can strain wiring leading to the EDU parking-lock actuator connector (C1YE113A). It lists P303F-15 and P303F-29 among possible stored DTCs. The diagnostic record title also references P303F, P303F-29, P07E6-00, and P272C-11, but the supplied evidence does not establish a standalone generic definition for P303F.
3. What system is affected?
Front Electric Drive Unit (EDU) parking-lock actuator wiring and connector C1YE113A.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- The official communication describes a ratcheting-type noise followed by an abrupt stop when vehicle speed has reduced to 5 km/h (3 mph).
- Possible stored DTCs include P303F-15 and P303F-29.
6. Possible causes
- The official communication identifies no retention to the front EDU, causing strain on wiring going to the EDU parking-lock actuator connector C1YE113A.
- The communication directs inspection of EDU parking-lock actuator connector pins for water ingress or corrosion.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
- Arrange qualified Jaguar service evaluation.
- Provide the exact stored DTC suffixes, such as P303F-15 or P303F-29, and report any ratcheting noise or abrupt stop at low speed.
- Do not attempt high-voltage or EDU wiring repairs yourself.
10. Step-by-step troubleshooting
- A qualified technician should inspect the front EDU parking-lock actuator connector C1YE113A and its pins for signs of water ingress or corrosion.
- The official communication states that required FRED submissions must be completed before installing a new front compartment wiring harness.
- Refer to Jaguar document JLRTB02012NAS5, “Gearbox Fault Detected” Displayed On The Instrument Panel Cluster, as cited by the official communication.
11. When to contact service
Contact an authorized Jaguar service provider. The supplied official communication applies to certain 2019–2021 Jaguar I-Pace vehicles in the US.
12. What the service center may check
- Check retention at the front EDU and assess whether wiring to the EDU parking-lock actuator connector has been strained.
- Inspect electrical connector pins at EDU parking-lock actuator connector C1YE113A for water ingress or corrosion.
- Confirm whether any required FRED submission is required before front compartment wiring-harness replacement.
13. Possible repair or resolution
- Not yet established by verified evidence. The official communication mentions possible installation of a new front compartment wiring harness, subject to completion of required FRED submissions, but does not establish that replacement is required in every case.
