Jaguar I-Pace Diagnostic Report

Initially, the Jaguar I-PACE displayed a high voltage system warning on the instrument panel and was completely unable to charge. We then confirmed the issue by attempting to charge the vehicle and observing no activity from the charge port. Subsequently, we carried out a comprehensive diagnostic check across all control units. During this process, we found that the on-board charger assembly was not communicating. Further investigation then revealed a blown supply fuse, which indicated a potential internal short circuit. To isolate the fault, we then carried out short circuit testing. As a result, the testing confirmed that the fault was internal to the on-board charger assembly, meaning the unit required replacement.

Jaguar I-Pace Repairs

First, the faulty on-board charger assembly was removed from the vehicle following manufacturer-specified procedures.

Next, a replacement on-board charger assembly was sourced and installed. All electrical connections were secured and verified for correct installation.

Finally, all required post-repair procedures were carried out as per the workshop manual, including system verification and safety checks.

  • Removed faulty on-board charger assembly with internal short circuit
  • Installed replacement on-board charger assembly
  • Completed manufacturer-specified post-repair procedures and safety verification

Resolution

A full functionality check was carried out following the repair. We confirmed successful communication with the on-board charger control unit and verified the vehicle was accepting an external charge correctly.

Following the repair:

  • Vehicle successfully repaired and returned to full operational status
  • Communication with on-board charger assembly restored
  • High voltage system warning cleared
  • Vehicle accepting external charge normally
  • Full functionality verified through comprehensive testing
  • Vehicle tested and cleared for customer collection
