B273C on Jeep
Digital crash input fault stored in the hybrid control processor (Jeep 4xe)
Severity: Inspect soon
FCA's bulletins pair B273C with the Service Hybrid Electric Vehicle System warning and say the vehicle may no longer enter Electric or Hybrid modes; the code involves the high-voltage system, so repair is dealer work.
It gets more serious if:
- Stop: The vehicle loses power or will not drive normally while the warning is on
