1. What does U0287-00 mean?

For certain 2021–2022 Jeep Wrangler vehicles in the US, U0287-00 has been documented with a “Service Hybrid Electric Vehicle System” message. The referenced manufacturer communication identifies U0287-00 as lost communication with the transmission fluid pump set in the TCM.

2. Technical explanation

The verified manufacturer communication states that U0287-00 may be present along with B273C-00. It identifies possible damage to the PIM-to-P2 high-voltage wiring harness, or inductive noise transferred from a damaged high-voltage harness to a low-voltage harness. The communication also describes possible electrical noise on circuit R414; the supplied evidence is truncated after that point.

3. What system is affected?

Hybrid electric vehicle system; transmission control module communication with the transmission fluid pump set.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • “Service Hybrid Electric Vehicle System” message displayed in the instrument panel cluster.
  • Vehicle shakes during a cold start.
  • Noise may be heard near the P2 motor.
  • U0287-00 may be stored in the TCM.
  • B273C-00 may also be present in the HCP.

6. Possible causes
